This issue has now been resolved. As Jeroen said, I needed to check on what
Dovecot was doing. As it turns out, specifically file paths in
/etc/dovecot.conf compared to /etc/postfix/main.cf :
/etc/dovecot.conf:
client {
path = /var/spool/postfix/private/auth
mode = 0660
user = postfix
group = postfix
}
/etc/postfix/main.cf:
smtpd_sasl_path = /var/spool/postfix/private/auth
As soon as both paths matched, Dovecot and Postfix were restarted to give
the following output :
[r...@caprica etc]# telnet localhost 25
Trying 127.0.0.1...
Connected to localhost.localdomain (127.0.0.1).
Escape character is '^]'.

Thanks very much to Jeroen and John for the tips.

Pete.
