Swicth from Postfix and Postfix admin to Qmail and ?

[xmichielx]

Hi,

Is there a way I can switch from postfixadmin mysql virtual users to Qmail with virtual users (vpopmail or such) ?
I use the maildir support and use ASSP as spam filter.
Btw, why is qmail-scanner (perl) being used and not the more faster and lighter simscan (C) ?

Thanks for any answer

Kind Regards,

Michiel

I looked at simscan and didn't like it for some reason. I don't remember why

[xmichielx]

It can most of the stuff that qmail-scanner can do but runs in C which, imho, is faster at high loads (when well programmed) then perl.
It is more lightweight and does not offer the same support but it does the job very well.
More can be found on http://www.google.nl/search?sourceid=ch ... il-scanner

But my main question is : what is needed to move from Postfix with Postfixadmin to QMail and a virtual user system with maildir?

[scott]

Simscan probably didn't support Archiving, per user and/or SQL settings, or some of the other AV scanners. Like I said, I dont really remember what the issues were exactly, it was quite a while ago that I looked at it last.

I couldn't tell you about the postfix to qmail migration outside of the context of a Plesk environment. For that it uses a middleware local delivery layer (called mail handlers) that abstracts that away from either MTA. Regardless of the MTA, the user mail box is maildir based and lives in /var/qmail/mailnames/DOMAINNAME/USERNAME/

Archiving is something clamd is doing not the milter..
It support al those features: http://www.qmailwiki.org/index.php/Simscan/README and I really recommend to use it in favor of performance for high load mail servers.
I will look into the qmail package and perhaps provide some wiki material for users who aren't using plesk but want a straight qmail setup

[scott]

Dunno about that, we've got some PG boxes out there doing over a million messages a day. Im talking about archiving for the purposes of litigation support, or compliance (SOX, GLBA, etc). Another feature was adding disclaimers to messages (again, for compliance support), and of course qmail-scanner supports more AV scanners than simscan.

[xmichielx]

Well it is your decision
I know simscan can add disclaimers and per user, domain and ip scanning and is really secure (less is more!).
It supports 2 virusscanners, it would be nice for users to choose between the two.

But I got another question about the Qmail package:

I was wondering if the qmail package is providing TLS and SMTP-AUTH?
A telnet does not show the TLS or STARTTLS command:

220 mailserver op je oog ESMTP
ehlo piet.nl
250-mailserver op je oog
250-PIPELINING
250 8BITMIME

A stated in :
/usr/share/doc/qmail-1.03/README.patches
* qmail-spp-smtpauth-tls-20060105.diff
-- adds in support for TLS, and SMTP_AUTH

Do I have to do anything to use the patch and enable TLS and SMTP-AUTH?
And how do I enable the qmail-scanner?
DO I have to use the QMAILQUEUE='' option somewhere?

Thanks for any help (really wanting to revert back to Qmail from Postfix).

Kind regards,

Michiel

I dont know that the patch used in qmail-1.03-24 is the latest and greatest, my guess is that its probably not. The original package was done in 2003, when I picked it up from Bruce Guenter. Aside from a minor update to it earlier this year, nothing was done to it between 2003 and 2009. This is one of those things that really needs a new maintainer Seriously, if you're interested in taking it over, the package needs it. I'd be happy to help out on the packaging side here, someone needs to just get into the integration parts and make sure the features are working correctly.

Looking at the .spec file is the TLS piece is from the SMTP AUTH code (Referenced as: http://members.elysium.pl/brush/qmail-s ... .30.tar.gz). I will bet that its totally out of date, which might be where the problem is.
