[SLUG] sendmail replacement

[<donohueb@xxxxxxxxxxxx>]

hi slugs,
i want to get rid of sendmail and put in an easier to configure
equivelant. i also want to transfer the current emails that are read
through sendmail.

so, can anyone suggest an easy to configure, secure, imap, email server
other than sendmail?

also, will this new email server read my current emails that are stored on
the mail server?

i hope i'm making sense with this.
thanks
ben
