Hi Rick,
Thank you.
I installed qmailmrtg7.
I don´t running SA and Clam when my server is slow.
[EMAIL PROTECTED] cat /var/qmail/control/simcontrol
:clam=no,spam=no,spam_passthru=no,attach=.vbs:.lnk:.scr:.wsh:.hta:.pif
Also, are you running the update_tmprsadh nightly (if your not it has to
generate a new key for every encrypted connection).
How can I know if my qmail is to generate a new key for every encrypted
connection?
Is this?
01 01 * * * root /var/qmail/bin/dh_key 2>&1 > /dev/null
You may also want to look at decreasing your timeoutsmtpd, put 180 or
something similar in /var/qmail/control/timeoutsmtpd to change the default
of 7200 (this will stop the spam zombie who hang around just using up a
connection slot).
I use timeoutsmtpd with 60.
Regards,
Joao

Hi Tren,
Sorry. My english is not good :).
My server is dual xeon 2.4 with 2 Gb RAM and HD SCSI 73 Gb.
I have problems with delivery delay when my server is with many
connections POP3 and SMTP.
I use isoqlog to analyze my email traffic, but I don´t have stats of POP3
and connections with my SMTP (RBL, no delivery, ...). Exists any software
to analyze POP3 and SMTP log?
qmailmrtg7 is a graphing tool for qmail/pop3/dnscache etc. You can find
it at http://www.inter7.com
When my server is slow, I have:
SMTP concurrent: 40 - 50
POP3 concurrent: 20 - 30
Load Average: 30 - 40
Are you running SA and Clam on the same machine ?
Also, are you running the update_tmprsadh nightly (if your not it has to
generate a new key for every encrypted connection).
I have many SMTP connections with "not existing recipient".
If that message is in the smtpd log, that's fine.

My server was very good. Between last monday and last friday it is very
slow.
How can I identify a possible attack?
Hope the above helps.

Rick
