A long time ago, in a galaxy far, far way, someone said...
More imput wanted!
does exim have the security reputation (in the real world) that qmail
qmail's reputation in the real world is:
* No maintenance - there are a couple bugs in the base qmail-1.03 package
that need to be patched before it can be used, and that's still not
counting the SQL, LDAP, SMTP AUTH and SSL patches *that all conflict
with each other* and add security problems at the same time.
* Very high security, as long as you don't add too many patches
* Very high speed
Exim's reputation isn't nearly that of qmail, but I'll take the occasional
Exim security bug in exchange for the power and flexibility (and feature
set!) any day of the week.
