Re: Runaway processes
I've been fighting a problem which may turn out to be similar. my spamassassin just starts falling behind and runaway threads could be the cause. I'm going to try adjusting --max connections per child (check docs for exact syntax). the default is 200. maybe someone else will jump in with a recommended number but I'm thinking the default may be way too high. a lower number will cause each child to shut down sooner. when the max number is reached the thread is stopped and a new one is created.

so you are running 30 per child and 6 children? 180 total. how many messages a day are you handling. I upped my children from 5 to 15 thinking that would help but it hasn't.

Sorry, no, that didn't come out right. There's only six children running at any time. Each will process 30 messages, then restart.

Forwarding mail address
Hi all, I do understand that this can sound as a very newbie question, however i have a doubt that i cant find an answer. We are using Spamassassin with procmail/sendmail. It is working fine, however, spam mail is being forwarded for a mail account, which is no longer valid. Ive been looking where this address is in the configuration, in order to forward those mails to another account, but no luck. Any suggestion? Best regards, Alexandre Cruzx

Re: Runaway processes
so you are running 30 per child and 6 children? 180 total. how many messages a day are you handling. I upped my children from 5 to 15 thinking that would help but it hasn't. I was thinking of taken connections down to 5 or 6 on 15 children. maybe I have it backwards? I don't have anything else running on this computer at all so I was thinking I wanted to use up all the memory with children. is that off? 30 connections on 6 children is a reasonable number for many smaller sites, the type that average probably less than 10K mails/day, at a guess. It should work reasonably well on the typical system with at least 500MB of memory and a 500MHz or faster processor. With a slower processor, or certainly with less memory, you might want to take the number of children down, and possibly the number of connections. Simple description on how this stuff works: spamd fires off some number of children determined by -m, with the default of 5. Each child takes some amount of memory. This is typically 30-60MB *per child* depending on the number of rules files you have. It will start a bit smaller than that, and will typically grow over the first dozen or so mails. If you have a lot of rules so your spamd children are taking 60MB each, 5 * 60 = 300MB. You better have a 512MB system or larger or you will be in heap big trouble. Even at 30MB, 30 * 5 = 150MB. This would probably work in a 256M system, but maybe not. You might want -m 3 or so in this case. Each child will process --max-conn-per-child messages before it dies and a new child is created in its place. If all mail was pretty much the same, and if the children did nothing but process mail, this really shouldn't matter. But the real fact is that all mail isn't the same. Some are very large. They should be limited to 250K or so, but some programs like qmail don't necessarily limit the mail size in the standard configuration. It is NOT a direct relation from mail size to spamd child size! A 250KB mail might easily crank a child up to 250MB! Once the child gets big, it just stays that way. If you feed large mails to SA, you cen get some really fat children. 5 children at 250MB each aren't going to fit well in a 512MB system. If you only let each child process a few messages before dying, if it happens to process one large message and gets big, it will only stay big for a few messages before going away. Chances are relatively small that all the children will manage to get fat at the same time, so you will probably survive just fine. With a large value of max con per child (like the default) it is pretty easy to get all the children fat at once. Spamd children also do other things than just process mail. Like doing database expiration runs. These tend to get the children very fat, especially have you have a database that has somehow gotten out of control. Again, this causes Bad Things(tm) if it happens to a lot of the children at once. Loren

Re: Runaway processes
is it better to run five children with 20 connections each, or 20 children with five connections each? Pretty much answered in my following mail. In general each child might us 30-60mb under NORMAL circumstances, so the amount of memory on your machine will determine the upper limit for number of children. In most cases you shouldn't really need less than about 20 connections (mails processed before dying) per child. If you do it may be a sign of other configuration problems in the system, such as not limiting the size of large mails going through SA.

Re: Forwarding mail address
From: Alexandre Cruz [EMAIL PROTECTED]
Hi all,
I do understand that this can sound as a very newbie question, however i
have a doubt that i can't find an answer. We are using Spamassassin with
procmail/sendmail. It is working fine, however, spam mail is being
forwarded for a mail account, which is no longer valid. I've been
looking where this address is in the configuration, in order to forward
those mails to another account, but no luck. Any suggestion?
Is fetchmail involved? If so then you might have to change contents
of either /etc/fetchmailrc or that person's account's .fetchmailrc
file.
For the /etc/fetchmailrc case all you need to do is redirect that
person's email by changing the local address stanza. If a fetchmail
is running for each account then you would need to disable that
account's fetchmail startup, where ever that happens. Then add
lines to some other account's .fetchmailrc to poll for and
receive the mail instead.
If you are not using fetchmail you need to punt a little. The sendmail
(or substitute) files might need an alias on that account. Others can
suggest tactics for this case.

If you do not already have a large amount of memory then adding
memory is one of the sovereign cures for slow SpamAssassin. As soon
as it goes to swap you're dead.
More processor also helps.
Fewer rule sets leads to poorer filtering and faster operation.
You are already processing much faster than my 1GHz Athlon which has
a gigabyte of ram. With all the rules I run it takes on the order of
a second and a half to scan for single messages. With multiple messages
at once there is some net advantage to the multiprocessing that happens.
It may be time to split the server into two machines.

RE: Load balancing spamd
We have 4 front end servers running postfix. These servers call and AV process on two additional AV servers behind the wall. Then these servers call spamd on two additional servers behind the wall. Those two servers have a simple MySQL cluster (running Linux-HA and DRBD). In all we have 8 boxes that handle all of our email for our clients. We are generating about 170k emails per day coming into the network. We recently upgrade all of the hardware to Dell Dimension 4700's with 1.5gb ram each. Budget was $5200. Machines are idle. Something new we have been looking at as well. We are looking at setting up simple relays that will run RBL on the front end and then just hand them off to our 4 backend servers.

I've been very happy with DNS load balancing. The frontend mxer runs tinydns on a local zone blah.local.domain.com, and an instance of dnscache with the round-robin patch is pointed to in resolv.conf. While I thought that the load balancing would be a little rough, looking at the stats I sent 17011 messages through #1, 17025 through #2, and 17016 through #3 yesterday. I can also weight this by having multiple records, ie: spamd1 gets three identical entries in tinydns spamd2 gets three identical entries in tinydns spamd3 gets three identical entries in tinydns spamd4 gets one entry O, some good bits! We have always been plenty satisfied with Bind, but maybe this is the straw that broke the camel's back unless anyone knows if Bind will behave the same way if we have multiple entries for one host?? that will leave spamd4 seeing about 1/3 the load of the other boxes. It's not clustering, but when using the -d flag: -d host Connect to spamd server on given host. If host resolves to multi- ple addresses, then spamc will fail-over to the other addresses, if the first one cannot be connected to. it should hit another box if one goes down. Or some easy scripting could remove the appropriate entries from tinydns if one machine stops responding. Speaking of low budget, we have three SA boxes, each of which has a 2GHz AMD processor, 1GB RAM. The first two cost about $550, the last one about $425. They are pretty crappy boxes with no RAID, etc., but it's cheaper for me to keep one more box than needed in the equation than to build out a few uber spamd boxes. They are in mini-atx cases, so they barely take up more room than an equivalent number of 1U boxes. I spawn 30 spamd children on each. I have been very happy with the performance so far. I'm surprised there's not a lot of folks out there who have done this before? Maybe they're all cheap like me. :) Awesome! Thanks for the advice!!! __ Do You Yahoo!? Tired of spam? Yahoo!

RE: Load balancing spamd
--- Gary W. Smith [EMAIL PROTECTED] wrote: We have 4 front end servers running postfix. These servers call and AV process on two additional AV servers behind the wall. Then these servers these being the AV server calls spamd or it goes back to the MTA first? How do you (make and) balance the calls to the AV servers? How do you (make and) balance the calls to the spamd machines? I am very interested in these details! call spamd on two additional servers behind the wall. Those two servers have a simple MySQL cluster (running Linux-HA and DRBD). In all we have 8 boxes that handle all of our email for our clients. We are generating about 170k emails per day coming into the network. We are edging up to 95K a day now on only two machines. You can imagine we are anxious to start using the other boxes we have rarin' to go! We recently upgrade all of the hardware to Dell Dimension 4700's with 1.5gb ram each. Budget was $5200. Machines are idle. Sweet. ;) Something new we have been looking at as well. We are looking at setting up simple relays that will run RBL on the front end and then just hand them off to our 4 backend servers. But since it works right now we're not going to fix it. Why? Because your DNS costs to query your RBL list in Postfix is very heavy/slowing you down? Are you going to mirror just one chosen RBL out there or a combination of several?? Do you run DCC in your SA environment? If so, you are over their recommended limit for hosting a DCC server (we are nearing it - 100K a day I think). Do you run a DCC server for yourself? Any issues to be aware of? Thanks a TON!! -Original Message- From: email builder [mailto:[EMAIL PROTECTED] Sent: Tuesday, August 02, 2005 5:19 PM To: Jason Frisvold Cc: Gary W.

I'm pretty sure this is a LVS question more than a spamc/d question, since I've no problems with the latter -- I am only asking here to see if anyone else does SA weighted load balancing. I kinda went the other way around.. I have multiple mail machines, each with their own instance of spamd. I use a Cisco 7206 VXR to do the load balancing. Works like a charm. Wow, a bit out of our price range here. :) We have also considered just continuing to build out MTA boxes each with an Amavis/Clamd and SA on them to share our increasing load (just use LVS to balance the incoming SMTP traffic and there is little reason to worry about balancing SA or Amavis/Clam), but our first choice is to split the layers -- have a couple separate machines that just do MTA-ish things, and a separate set of boxes that serve as a SA (and Clam-av) farm. The thing that's better about doing it that way is the redundancy that you don't get if you aren't sharing spamd instances across all your MTA machines. Technically, this should be feasible with just plain DNS load balancing, but in our current medium/low budget scenario, we don't have the rackspace to have numerous boxes that are dedicated ONLY to SA/clam, thus our desire is to figure out a way to *WEIGHT* our spamd balancing. I'm surprised there's not a lot of folks out there who have done this before? Thanks again! Start your day with Yahoo! - make it your home page http://www.yahoo.com/r/hs __ Yahoo!

Re: Bayes: not enough usable tokens found
Hum. I can see some messages are being caught via the Bayes test, but I would think Bayes would find many more as I have close to 5000 SPAM in the Bayes system. I get at most 15 messages a day flagged as SPAM while I receive approx. 100 messages a day as non-SPAM but should be flagged as SPAM. I have started to include the Spamassassin footer on all messages to get a handle on what passes in the "non-Spam" messages. Any thoughts on how to improve this would be helpful.

OT: RBL for dynamic no reverse DNS lookups
OT: RBL for dynamic no reverse DNS lookups I'm trying to find an RBL which will return a standard RBL return code (like 127.0.0.2) if/when the IP passed to the RBL doesn't have a reverse DNS entry. (1) I know that SA doesn't have a need for this as another function is already available in SA for this. But I need this for a **different** utility, not SA (which is why I said, OT). (2) This other utility doesn't have the option to check for no reverse DNS, but CAN do whatever general RBL lookups I tell it to do. Also, I don't have access to this utility's source code. However, if I can find this kind of RBL I mentioned, then I can use this utility's RBL lookups against that kind of RBL to accomplish checking a message's sending server for no reverse DNS. But, again, doing lookups on (reversedIP).in-addr.arpa is NOT an option in this utility because it **only** works with the traditional RBL responses, which are always numeric, unlike reverse DNS lookups. (3) I know that some aggressive RBLs factor in no reverse DNS... but, instead, I'm looking for an RBL which would do a DYNAMIC lookup to see if there is no reverse DNS, even if that RBL hasn't checked that IP before or hasn't previously added that IP to it's no reverse DNS nameserver database. (4) And, of course, I understand that it is NOT a good idea to block **solely** due to a sending server's IP not having a reverse DNS lookup. Rather, I'm using this for auditing, testing, and other things. Thanks, Rob McEwen PowerView Systems

Re: Bayes: not enough usable tokens found
Hum. I'm a little confused by that SA score stuff on the bottom of the message. If it refers to a message that should be spam you have two serious problems. If it referred to a message from this list you may have a serious problem and a less serious problem. pts rule name description -- -- -3.3 ALL_TRUSTEDDid not pass through any untrusted hosts 0.0 HTML_30_40 BODY: Message is 30% to 40% HTML 0.0 HTML_MESSAGE BODY: HTML included in message 0.0 HTML_TITLE_EMPTY BODY: HTML title contains no text -2.6 BAYES_00 BODY: Bayesian spam probability is 0 to 1% In general ALL_TRUSTED shouldn't be firing for messages coming from an external source. This makes me wonder if you have trusted_hosts and trusted_networks set correctly. In general SA (and especially Bayes) shouldn't be seeing this list, since it has a lot of real spam floating through it, and other spammy tokens. It is far better to use postfix or whatever your router is to bypass this list around SA. If that header referred to a spam, BAYES_00 says that Bayes thought it was guaranteed ham. That would be a sign that you have a corrupted bayes database. Loren
