[Mimedefang] Delaying "use" of MIME modules

[Jonas Eckerman]

Hi

The new scheduler makes it possible to save memory by delaying the compilation of modules 
until they are actually needed and I'm experimenting with this. I've done that with the 
modules used by my filter and those mimedefang.pl handles in "%Features".

The MIMEDefang children have gone from over 60MB each (with the old scheduler) 
to about 15MB for those children that never sees a MIME entity.

The only "big" modules that are still loaded for every child are the MIME tools 
modules.
Would it be feasible to move those modules into %Features as well? Or are they 
used in too many places in the code for this to be a quick simple change?
It might be worth it for some systems.

Of course, with my huge filter it might actually make a bigger difference to split the 
filter into parts that are "required" when needed. :-)

Regards
/Jonas

[Mimedefang] info cuestions

[juanlopezz]

In this order i have the next info:

filter_sender (From) - ($sender, $ip, $hostname, $helo)

filter_recipient (To) - ($recipient, $sender, $ip, $hostname, $first,
$helo, $rcpt_mailer, $rcpt_host, $rcpt_addr)

Filger_begin - subject and other ($recipient, $sender)

I need to know subject, sender, recipient in filter_sender ¿I can obtain
this data?

Also i need know the size of a message (i use sendmail/milter) Sendmail
have this data but i do not know how i can get this data. I try with
read_commands_file();  $SendmailMacros{} but no have the size and no have
info about recipient and sender than i can use in filter_sender.
$SendmailMacros in this point (filter_sender) i use authen for authid.

Thanks.

No, because that information hasn't been received yet.

The only reliable way is to measure the size of the file ./INPUTMSG
from filter_begin

David.

RE: [Mimedefang] mimedefang.sock unsafe

[Josh Graham]

One thing I did was put a sleep 3 in my sendmail startup script to give
mimedefang 3 seconds before sendmail starts. That got rid of the sock
error.

Subject: [Mimedefang] mimedefang.sock unsafe

I looked on the mailing list archives for the past problems that have
this error and I was wondering if anybody had more details on how to fix
this problem without restarting the actual machine.

I have 2 servers running RH ES3, running Mimedefang 2.57 and
sendmail-8.12.11-4.RHEL3.4. Under normal circumstances, they share the
load pretty well. Today I noticed that my mail01 server was loaded
(35+) while my mail02 server had no load at all. I checked the logs for
mail02 and I saw the following:

Milter (mimedefang): local socket name
/var/spool/MIMEDefang/mimedefang.sock unsafe

Permissions are fine, as MD starts up normally after a reboot/restart
(unless I see this error). If I do a "service sendmail restart", the
mimedefang.sock file never gets created, and so the MD service fails as
well. Doing a restart on the server fixes the problem and mail processes
normally once again. What information would be needed to try and
determine how to go about fixing this problem without a restart?

Thanks.

Thanks Josh,  did you put sleep in any particular spot of the startup script?

[Mimedefang] LZW, Gifs, and fingerprinting stock spams

[Philip Prindeville]

I'm trying to do some stochastic analysis of stock spams and
figure out if there's a common fingerprint that can be used to
identify them...

But first, I'm bumping up against some Perl issues.

Seems that there aren't many modules out there that help
deconstruct Gif formats.  I'm using Image::Info::GIF, but
need to decompress the compressed data portion.  I tried
to take the data and pass it to Compress::LZW directly,
but most GIF's (at least for stocks, which don't use many
colors) use 4, 6, or 8 bit codesizes.

Unfortunately, Compress::LZW only handles 12 or 16
bits...  Anyone familiar enough with either GIF formats
or how to decompress the data to offer a leg up?

Thanks,

-Philip
