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?
When my server is slow, I have:
SMTP concurrent: 40 - 50
POP3 concurrent: 20 - 30
Load Average: 30 - 40
I have many SMTP connections with "not existing recipient".
My server was very good. Between last monday and last friday it is very
slow.
How can I identify a possible attack?
Thank you
Joao

Hello,
I am working with qmail toaster by http://www.shupp.org/toaster/.
Is it the better performance instalation?
My server is very slowly :(
You'll need to give something specific here. Bill Shupps Toaster is widely
popular. I use it myself and have no issues with performance. What are the
specifications of the hardware you've implemented it on. What specifically
is performing slow? Is there anything else on this server? Approximately
how many mailboxes are housed on this server? How many deliveries per
second/minute/hour/day (whatever is easiest to convey) and do you have any
idea what your peak concurrent deliveries are? You need to provide as much
information as possible before asking such a general question.
Regards,
Tren
