I'm a bit dumbfounded by how to configure the plesk mailserver. I've read it uses qmail, but running qmail in the console gives me a command not found. sendmail on the other hand does seem to react, but trying to use the commandline to send an email doesn't deliver my mail (although I get no exception either).
Anyway, what I'm trying to do is send mails from within PHP (with SMTP to localhost). What I do not want however (and what plesk tries to do apparently) is host the mailing for my domain. Instead, the real mailserver for my domain is on another server, but to still retain mails when that would go down, I'd like a local relaying smtp server.
Any idea how to get this done, or is this impossible with plesk's built in version?
