    I need assistance about this topic.If you are an expert on this topic and realized a project about it please mail me: murattas6@gmail.com

    hi richiefrich,

    What is the capacity (# of users and connection rate) of your system?

    How many servers did you use to utilize it?

    Thanks for your reply..

    If it were me, I'd do a test install and config of both qmail and postfix. Sendmail does have some security issues that you probably dont want to bring to your network.

    They should both be fully capable of dealing with heavy load, so it's really a matter of which you find easiest to configure. Like I said, try them both.

    Linux Weekly News recently had a comparison of four mail transfer agents. It's a two-part story. See part 1 here and part 2 here.

    traffic generating script

    ok I will try both..

    But to simulate the real environment I need a script generating mail traffic via smtp,pop3 etc.It should send mails with attachment.

    Do you know any script doing these?
