Re: QMAILQUEUE patch - how to apply?
Hi, after sending my last message something happend and qmail stopped delivering local mail: Oct 25 02:02:33 be-01 qmail: 972439353.047394 starting delivery 258: msg 134477 to local [EMAIL PROTECTED] Oct 25 02:02:33 be-01 qmail: 972439353.047854 status: local 1/10 remote 0/20 Oct 25 02:02:33 be-01 qmail: 972439353.072365 delivery 258: deferral: Unable_to_ find_alias_user!/ Oct 25 02:02:33 be-01 qmail: 972439353.072849 status: local 0/10 remote 0/20 I rebuilt the whole system, now it works fine. I copied the deferred messages, fixed the queue, but they still do not deliver. I'm very confised - how can some messages get delivered and other not? and why they are not going to the postmaster? Postmaster is "catch all" user. And has this somethig with the patch? Milen

Sending mail to WWW
Hi, I have installed qmail and everything seems OK except for sending mail out to the WWW. If I remove/rename the rcpthosts file I can then send mail out to any domain, but I presume this is not the correct way to solve this. I have our servers full domin and domain name listed in the local and rcpthosts file and have no problem with sending and receiving local mail or receiving mail from the WWW. Thanks in advance.

Is there a bug in the pop3 server?
Hi, me again... :) My qmail setup otherwise works just fine, but I think I may have stumpled over a bug in the code... Like I have stated before, a friend of mine was writing a pop3 retrieval component (thanks to all who sent messages to his mailbox...) and cam upon an interesting thing: When connected to the qmail server, he tried a test run of his component... And it worked... So I tried the following: Opened two separate sessions (telnet ... pop3) and listed the messages in both. Great... The same. Now I deleted a message in one session and quited the session (quit :) When trying to read the message in the other session, it failed! Ok, I said... It fails... Nothing to worry about, I mean, you get an error message, but nothing bad happens. But still... Lets see, what RFC 1939 says about this: = Once the POP3 server has determined through the use of any authentication command that the client should be given access to the appropriate maildrop, the POP3 server then acquires an exclusive- access lock on the maildrop, as necessary to prevent messages from being modified or removed before the session enters the UPDATE state. = Is this actually the behaviour I described? :) Dont get me wrong here... I dont mind this "error", but wanted to let all you know (in case someone didn't know about it... Goran P.S.: If someone wonders... I'm using the qmail-pop3d program with Maildir's... Otherwise there are no problems (if you take this as a problem)

I have no idea on how this was introduced into your RPM, since the original patch at http://qmail.mirrors.Space.Net/local-bind doesn't seem to have that problem. Crap. I just released a new version of it yesterday. Hmmm. That must mean you're the only person using this feature. Shows how really useful it is. I'll apply the fix to the next release. So, could you tell me why you need it? Please followup to the mailing list. Well, it is a way to bind all outgoing SMTP sessions to a certain IP. Having multiple services on a single host means that I can give proper names that resolve properly in the reverse DNS. So I can have me/helohost actually matching its reverse DNS name. So that people trying to read headers don't start crying "forgery" if the host names do not match (especially since primary IP of that server may happen to be from a different domain) There are several patches on www.qmail.org trying to do this, the one you have in the RPM is the most flexible one, so it has my vote. Side note: Could you please stick a README into the RPM detailing which patches are applied and what they do, ie. how your RPM differs from the "pristine" QMail ?

Re: Sending mail to WWW
Hi Daniel, first: the Internet is not the WWW although many people see them as the same. They are not. I have installed qmail and everything seems OK except for sending mail out to the WWW. If I remove/rename the rcpthosts file I can then send mail out to any domain, but I presume this is not the correct way to solve this. Do you use ucspi-tcp (tcpserver)? If not, you should do so and set the RELAYCLIENT environment variable for your internal network. This is explained in Dans FAQ, see http://cr.yp.to/qmail/faq/servers.html#tcpserver-smtpd and http://cr.yp.to/qmail/faq/servers.html#authorized-relay Regards, Frank

POP3 on tcpserver
Hi all, can someone xplain me how to modify the current pop3 service from inetd to tcpserver ? Currently inetd.conf shows: pop-3 stream tcp nowait root/usr/sbin/tcpd /var/qmail/bin/qmail-popup ourhost.nl /bin/checkpassword /var/qmail/bin/qmail-pop3d ./Maildir/ But I'd like to run it with tcpserver so I can get rid of the DNS lookup's since that slows the pop3 service down enormously; Also, I noticed some postings about SSL on POP3, how does this work ? And how do you configure Outlook to use SSL on POP3 (didn't check if this is supported standard yet) BTW, Maildir is definitly easier then I expected, I used mailbox before which didn't cause problems, but Maildir's are clearer in use :) Now I'm currently using fastforward to be able to use /etc/aliases.cdb, but is this slower than qmail's native aliases ? If so, how does it work exactly ? The manual is very cryptic about this... All I know is that you have to create a .qmail file in the alias directory, but I don't understand how this file should be named and what it's contents are supposed to be. Thanks a lot for some help on these questions :) Regards, Jeroen ten Berge

Switching to unlocked POP servers gave them free time. Dont get me wrong here... I dont mind this "error", but wanted to let all you know (in case someone didn't know about it...

My first ideia was to use ezmlm with suport to sql database, but how ezmlm cant connect to a SQL-Server, I decided to use a perl script (and perl module FreeTDS), to make queries to the sql database, insert into my local mysql database and then let ezmlm do the hard work for us. First, is there a better aproach? (I cant find). I would like to use ezmlm, because I think it will deliver the emails the most quickly possible.

SMTP auth patch on firewall?
Can some one help me wrap my brain around something? I've got a mailserver behind a firewall using qmail with the LDAP patches. The firewall is running the same qmail executable (the LDAP part is fully enabled and as I type this it suddenly occurs to me that this may be a security issue, although maybe it would solve the problem I'm trying to solve right now). I'd like to patch my smtpd to allow SMTP AUTH on the firewall. What do I need to do? I'm thinking that since I have access to the LDAP server from the firewall, I can validate the users against that. Will it "just work" if I have both the LDAP patches and the SMTP AUTH patch installed? Is it a mistake to have an LDAP patched qmail on my firewall?

What to do about these barelinefeeds?
Well first off, can someone explain to me the reasoning behind the bare linefeed restriction? I hope it is an actual standard that this restriction is trying to make other MTA's adhere to. So anyway, 2 questions: 1) Does anyone have a list of commonly used mail servers that violate this? Personally, I've seen a few instances of mail servers going crazy hitting me once per second trying to deliver mail and just getting status 256 over and over, I'm thinking it's probably the bare linefeed thing causing this behavior and if they're on a bigger pipe than my qmail server, it really hurts my connection. I'd really like to know which servers might exhibit this behavior. Most recently, I tried to sign up for an eval version of Legato's backup software and all I see in my mail logs is a connection from augusta2.legato.com every four hours with a status of 256, nice huh? 2) The important question now is, what kind of error does the user get when their mail server finally gives up? Does it look like the mail was just undeliverable? I know qmail issues the error code that causes the mail server to try again. After that time on the remote server expires, I'm worried that users who may be mailing someone at a domain I host will be getting an error message that makes it look like a problem with my mail server, pissing my customers off at me. Thanks all, Dave

RE: What to do about these barelinefeeds?
Thanks, I hadn't seen that link before. I'm sorry, I meant that the 256 was the status code I see in my smtpd log. But, in searching the archives, I saw reference to people saying the bare LF generates a 451 and not a 553.

Kernel Panic in regards to tcpserver
OK. So everything has been going along fine until this morning. All of a sudden I noticed that our new qmail server stopped responding. I went to the qmail server and noticed that there was a kernel panic message on the screen and then something about tcpserver. Since the first time it seems that the machine will only stay up and running about 10-15 minutes. So I'm starting to get in a bind on this one. I'm hoping someone can help me out with this since I've never seen anything like it before. Below is the logs from syslog relative the lockup. Any help would be greatly appreciated.

Re: Kernel Panic in regards to tcpserver
You have a kernel or hardware problem. If qmail is mostly what you are running then it is likely that it will trigger the kernel bug or hardware problem. (If you were mainly running sendmail on that box, then it's likely that it would trigger that kernel bug or hardware problem.) You'll need to investigate the state of your hardware and your kernel with a view to changing of fixing one or both of them. If you haven't changed kernels in a long time then it's likely to be a hardware fault: motherboard gone bad, faulty memory, who knows... Does your hardware provide good self-diagnosis? Regards.

If the crashes continue, consult a support group for your OS. They might be able to help you narrow down the cause of the problem. The problem is *not* qmail, vpopmail, or qmailadmin. Applications *cannot* cause kernel panics. -Dave
