Ok, this turned out to be SELinux.
If I turn off SELinux then I can start Dovecot using init.d.
So now I tried to send a test mail using telnet:
# telnet localhost smtp Trying 127.0.0.1... Connected to localhost. Escape character is '^]'. 220 grp-01-50-90.localdomain ESMTP Postfix ehlo example.com 250-grp-01-50-90.localdomain 250-PIPELINING 250-SIZE 10240000 250-VRFY 250-ETRN 250-ENHANCEDSTATUSCODES 250-8BITMIME 250 DSN mail from:steve@example.com 250 2.1.0 Ok rcpt to:john@example.com 250 2.1.5 Ok data 354 End data with <CR><LF>.<CR><LF> Hi John,

And the log: # tail -50 /var/log/maillog Dec 30 10:45:31 grp-01-50-90 dovecot: Dovecot v1.0.7 starting up Dec 30 10:45:31 grp-01-50-90 dovecot: auth-worker(default): mysql: Connected to 127.0.0.1 (mailserver) Dec 30 11:03:02 grp-01-50-90 postfix/smtpd[6942]: connect from localdomain.localhost[127.0.0.1] Dec 30 11:04:21 grp-01-50-90 postfix/smtpd[6942]: 4F1D2D8055A: client=localdomain.localhost[127.0.0.1] Dec 30 11:05:06 grp-01-50-90 postfix/cleanup[6967]: 4F1D2D8055A: message-id=20071230160421.4F1D2D8055A@grp-01-50-90.localdomain Dec 30 11:05:06 grp-01-50-90 postfix/qmgr[2123]: 4F1D2D8055A: from=steve@example.com, size=408, nrcpt=2 (queue active) Dec 30 11:05:06 grp-01-50-90 pipe[6982]: fatal: pipe_command: execvp /usr/lib/dovecot/deliver: No such file or directory Dec 30 11:05:06 grp-01-50-90 postfix/pipe[6980]: 4F1D2D8055A: to=john@example.com, relay=dovecot, delay=67, delays=67/0.19/0/0.1, dsn=4.3.0, status=deferred (temporary failure.

So I checked and 'deliver' is not in /usr/lib/dovecot. It is in /usr/libexec/dovecot. So how do I fix this? Here is what is in postfix master.cf: dovecot unix - n n - - pipe flags=DRhu user=vmail:vmail argv=/usr/libexec/dovecot/deliver -d ${recipient}
So why is it referencing /usr/lib/dovecot/deliver ????
Thanks, Gerry
