Newaliases is part of Postfix's Sendmail compatibility interface. If you had both installed simultaneously, I can see how that might cause Postfix's versions of newaliases / sendmail / mailq to not be present. You almost certainly want them, as other applications tend to rely on their presence.

You might want to first try running system-switch-mail (if not present, just do yum install system-switch-mail) to choose Postfix as your system's MTA. That might be enough to get all the pieces in place. Otherwise, I'd suggest removing both Sendmail and Postfix and then re-installing Postfix only, followed by system-switch-mail.

Hi

Thank you for the response.

It seems to be working if I have sendmail installed but not running.

Hi All

I'm posting here because I use this setup. I'm having trouble setting up the mail.

My mail seems to be eaten up...

In the maillog file I get:

I guess the MailScanner doesn't copy the email to where it should be, just delete it...?

Your mail is in the postfix local delivery queue. postfix is reporting an error:

Aug  7 09:49:23 li73-31 postfix/error[9972]: 65A0F27283: to=<andre@paranoidandroid.co.za>, relay=none, delay=4.9, delays=4.8/0/0/0.05, dsn=4.3.0, status=deferred (mail transport unavailable)

because the specified local delivery transport is unavailable:

Thank you for the response.

The week was long and I'm a bit slow.

Is private/dovecot a directory or the bin file? I've created a directory in /var/spool/postfix/private/dovecot (just after I posted the previous post). Now I get a

Connection refused

error

Did you install Dovecot yet?

Yes this is my setting:
