monitoring postfix performance
 
assuming I send a bunch of emails from my server and each mail is assuming 1 kb, how can I monitor the max outgoing mails my server can handle?
im using ispconfig 3 with centos5 and postfix.
thanks in advance.

you can e.g. write a secript that sends a few thousand emails where you put the exact timestamp in the subject and about 1k of text in the body. Then you can check on the receiving server when the last email arrived (file timestamp of the email file in maildir vs. timestamp in the subject). Before you test that, sync the time of both servers with ntp.

not a bad idea. i assume your talking about a php script. If i don't find another solution that's what i might do, however i was looking for an easier way to find out if postfix monitors this information. I've heard postfix comes with test tools such as smtpsink and stree but I've never used them, nor do i know how to use them. I was hoping ispconfig 3 has something like this already in the web interface. i think the test script would be less accurate because if I'm sending mail to a live mailing list, so each recipient will have a different route to from my server to their final destination. thanks for your idea. is there anything else you can possibly suggest?
