Re: [Mimedefang] Re: Problem on attachment name
I've sent a bug report to Apple but I don't know if they respond quickly and certainly it can pass a lot of time before all Apple Mail users upgrade. Before this every mimedefang/f-secure server that receives AppleMail mail with spaces on attachment name will fail... Apple confirmed the bug and says they are working on it. Now I really need a temporary workaround. Any hint ? Thank you -- Ing.

Re: [Mimedefang] Problems with outgoing bounce messages, unkownuser, plus to many bad files in sendmail queue
I've changed my sendmail.cf Timeout option to these values and notice that only a couple of bounce emails get generated (vs hundreds before) I am not sure if the otpion "O Timeout.queuewarn.dsn=0s" is the one that stops sendmail from sending out those non deliverable messages Do you know if any of these options may cause any unwanted behavior? I realize that this is a sendmail fqa but imagine if someone knows the answer out of the head that will be great help for me. I still see more files in sendmail queue than reported in mailq command. Is there any mimedefang filter code to block these extra files from writing into the queue? Thanks!

This will cut down substantially, on "stale" messages in the queue, that are destined for unresponsive or non-existant servers. Sendmail's default for confTO_QUEUERETURN is an absurd 5 days (actually, it's 5 days, 23 hours, 59 minutes). That's 6 days of garbage in your queue. Try setting that to 2 days. You'll see a lot less garbage in your queue, and your users wont have to wait close to a week to find out a valid (but stalled) mail they sent didn't go through.

Yes, CanIt uses MIMEDefang as it's core, wrapped with a web GUI and a database backend for clustering. I'm using CanIt Pro to filter email for 71 school districts in Western NY with great success. I have had very few problems, and Roaring Penguin provides great support. I did set up a MIMEDefang box before investigating CanIt Pro and liked the way it works (see previous messages about milter operation). CanIt Pro has also proved to be very cost effective for our organization in addition to doing a great job filtering mail. Disclaimer: This has been an unsolicited testimonial from a satisfied user.

If they are command-line virus-scanners, performance will be terrible. If you have as a requirement the need to run multiple command-line virus-scanners on large quantities of e-mail, then MIMEDefang is the wrong choice.

[Mimedefang] Re: compare mimedefang to mailscanner
But can you run multiple virus scanners with mimedefang? How will that add to the startup costs of more than one virus scanner? Some virus scanners don't have a socket interface that you can pipe into, and some that do won't let you pipe between them. Multiple virus scanners help quite substantially on many new viruses, as the time lag between detection and signature update can be different between them. I am currently running mimedefang for check_against_smtp_server and mailscanner with spamassassin for virus scanning and spam. If I add a supported virus scanner in mailscanner, I just have to add its name to the config file and reload. How much code do I have to write in mimedefang to do the same? I wanted to do a trial of f-prot. Just installed the rpm for f-prot, added its name to the config file, and now my system is scanning with 4 virus scanners. Took 5 minutes of my valuable time. It took several hours getting mimedefang going on just the smtp checks. Sure, mimedefang is like a swiss army knife. In the right hands, it can do almost everything. ...but I am no McGyver, so I can't save the world with just a swiss army knife! I need more tools in my tool chest! So to end this rant, use the tools you are comfortable with. Both work very well, and you can do much with either one. The only one that can tell you which is better is you, and your usage, skill level, and time available. ___ NOTE: If there is a disclaimer or other legal boilerplate in the above message, it is NULL AND VOID.

MIMEDefang just sends the command: SCAN /path/to/filename and clamd reads the file or files to scan itself. General comments: 1) Disk I/O: MIMEDefang will use less disk I/O than Mailscanner because you're not queueing every mail message twice. In fact, if you have a modern version of Sendmail with SuperSafe set to PostMilter and MIMEDefang rejects or tempfails a message, that queue file won't be sync'd to disk. 2) CPU: MIMEDefang and Mailscanner probably use similar amounts of CPU time. SpamAssassin and virus-scanners are pigs, no matter how you look at it. :-) 3) Overload: If you are CPU-bound, Mailscanner will handle overload better than MIMEDefang, because there are no "hard" constraints on how long it's allowed to take. During temporary overloads, Mailscanner will just let your queues grow, while MIMEDefang will tempfail mail (and make things worse because of all the retries.) If you are I/O bound, then Mailscanner will probably be worse than MIMEDefang because of the extra queue I/O.

Tried Postfix+MailScanner+clamscan in another computer and it's very slow, because Mailscanner doesn't work as a deamon, and doesn't use Clam as a deamon either, but relies on running clamscan for every email. The overall result is extremely slow. I forgot to respond to this part: This is entirely what I was talking about with "economy of scale". With MailScanner, if you're scanning messages in such small batches, and so infrequently, that you're spending more time with the clamscan start-up/initialization overhead, then it will seem like MailScanner is slow. On the otherhand, if you're scanning 100's of messages per minute, in 100 message batches, then the start-up overhead of clamscan or sweep is so insignificant compared to the actual scanning cost, that you get a HUGE benefit from this economy of scale. This actually far outweighs the IO bottleneck of clamd's socket. MailScanner doesn't have any support for clamd exactly because clamd would slow down MailScanner in a BIG way. (a few years back I tried to do a comparison between MailScanner+clamav_perl_module and MIMEDefang+clamd to see if either could be improved by the other ... and I couldn't -- each of them is going in such a different IO model that you can't really imply something about one's model based on your experiences with the other model... the only answer is: MailScanner is fastest with the perl ClamAV module, and 2nd fastest with clamscan ... but clamd is a significant liability with MailScanner; meanwhile, MIMEDefang is _exactly_ the opposite -- using clamscan with MIMEDefang causes a significant slowdown because you pay the start-up overhead of clamscan with every message ; using the experience of one to try to speed up the other will just lead you to headaches) ___ NOTE: If there is a disclaimer or other legal boilerplate in the above message, it is NULL AND VOID.

My experience is exactly the opposite. In an environment with .25M to 1M emails per day, MailScanner did just fine on little SunBlade 150 workstations (four of them, load balanced). Sure, the latency (between accepting a message, and then handing it to the back-line POP/IMAP/Webmail server) could be up to 10-15 minutes, but it didn't get any worse than that. In contrast, trying to run MIMEDefang on those same systems was pointless. In order to run enough child processes to keep up with 1-2 messages per second, the load would shoot so high that it the systems would stop accepting email. One of the reasons why it took 2 years to move from MailScanner to MIMEDefang, at work, was a) the fallout from trying to do it on that hardware, b) the upgrade cycle for moving to Sunfire v220's so that the systems were fast enough to do the checks during the SMTP session. ___ NOTE: If there is a disclaimer or other legal boilerplate in the above message, it is NULL AND VOID.

Re: [Mimedefang] compare mimedefang to mailscanner
Mike Campbell wrote: I have been using mimedefang for a couple of years now and just today ran across the mailscanner program. On first glance it appears that the 2 do about the same thing. Have some of the experts here tried both of these and have a comparison as to how they differ? Is it worth my while to spend time trying to configure mailscanner? For what it is worth my mail server currently processes around 500-600 messages a day on a P3 500 mhz machine with 128 meg of memory. The big differences are: 1) MIMEDefang happens during the SMTP session, so you have the option to do things like tempfails (SMTP 4xx return code), which allows you to do Greylisting, or rejections (SMTP 5xx return code). MailScanner needs 2 mail queues (one for pre-scanned mail, one for post-scanned mail), and does not happen during the SMTP session (so your only options are deliver, clean, silently delete (bad), send back a bounce report (bad)). So, MIMEDefang lets you _reject_/refuse-to-accept a virus, a bad attachment, or a high-scoring spam message. MailScanner does not. (this also means that MailScanner has a sometimes significant latency between when it accepts a message, and when that message finally gets to the local recipient; in large environments this latency can be noticeable, and cause complaints from your users) 2) MailScanner gets an economy of scale out of doing HUGE volumes of anti-virus scans in one pass. For example, MailScanner's 2 fastest virus scanners are the command-line sophos sweep, and the command-line clamscan (not clamdscan; clamd significantly slows things down for MailScanner). In contrast, these are very SLOW mechanisms for MIMEDefang, because MIMEDefang doesn't get that economy of scale (with MIMEDefang you really DO want to use clamd). For your 500-600 messages per day, you probably wont really see that economy of scale with MailScanner. 3) MIMEDefang lets you specify the order of checks. With MailScanner, you HAVE to do SpamAssassin first, and Virus Scanning last. That means you're running the very CPU expensive SpamAssassin checks on viruses. With MIMEDefang, you can set the order just by re-arranging code in your mimedefang-filter. 4) MIMEDefang also lets you do other kinds of checks: checks on the relay, checks on the sender, checks on each recipient, all before you do any other spam/virus checks. This lets you do anything from blocking suspicious content, to doing the equivalent of "milter-ahead" to verify that a destination host has the recipient's address (with MailScanner you have to either use milter-ahead, or keep an up-to-date aliases file, or something like that). That said, you CAN use them together. You could use MIMEDefang for fast checks and during-SMTP-session checks (relay checks, helo checks, sender checks, recipient checks, attachment filename checks, maybe clamd anti-virus checks), and then use MailScanner for bulk checks and checks that would slow down your SMTP sessions (other virus scanners, SpamAssassin). This reduces the amount of messages you're submitting to MailScanner (and thus SpamAssassin), and if you do clamd with MIMEDefang you're not going to be spamscanning most of your virus traffic nor bad-attachment traffic. Personally, I stopped using MailScanner at home 2 years ago, and stopped using MailScanner at work 2 months ago. I greatly prefer MIMEDefang. But, it does require a bit more CPU (so that you can do all of those checks on a per-message basis, and during the SMTP session before it times out). But your traffic levels shouldn't be a big burden to most machines. MailScanner is a great package. I just prefer to have the option to reject content instead of cleaning/marking it and then delivering it. (and, to be fair, I will probably stop using MIMEDefang at home, in the not so distant future; I am switching MTA's from Sendmail to CommuniGate Pro; CGP doesn't use the milter interface, but uses a plugin interface of a different kind ... so I'm in the process of building up the infrastructure for those plugins; it's nothing against MIMEDefang -- if CGP had a means of using milters, I would keep using MIMEDefang with CGP) ___ NOTE: If there is a disclaimer or other legal boilerplate in the above message, it is NULL AND VOID.

The biggest difference between the two is that MIMEDefang, being a milter, can act on a message DURING the original SMTP conversation thus allowing rejections, grey/black/whitelisting, and other actions to be taken before the entire message is even accepted. If you REJECT a connection while it is in progress, there's no need to generate a separate bounce notification after the fact, which will likely just clog up your outbound mail queue. You just send a rejection to the connecting server, and drop the connection, effectively slamming the door on the spammer. With mail scanner, you've already received the message in full (and said "thank you very much" to the spammer), before you even begin looking at what you've just received.

Re: [Mimedefang] filtering words from the subject line

See the list archive, why this is a bad idea. If you insist in using it: Add this conditional into the filter_begin() function: if($Subject =~ m// ) { return action_bounce("bad subject"); } Put your regex between the slashes of m//.
