Hi, Please understand I am an absolute beginner at terminal unix command line and everything to do with setting up an unmanaged VPS. However I have done everything on my own from reading in forums and tutorials. I've got as far as installing everything for my drupal site which is up and running EXCEPT for mail which is proving very hard to learn. I have been following this tutorial : http://library.linode.com/email/postfix/dovecot-mysql-centos-5#sph_set-the-hostname postfix has no errors on restart and neither does dovecot but running command: telnet localhost 25 it just gets connection closed by foreign host. Also I have to force seeing log by: cat /var/log/maillog and get the following last line: postfix/error: 8CA3B10D38: to=<[email protected]>, relay=none, delay=163519, delays=163519/0.02/0/0, dsn=4.4.1, status=deferred (delivery temporarily suspended: connect to alt2.gmail-smtp-in.l.google.com[2607:f8b0:4002:c05::1b]:25: Network is unreachable) Please any help would be greatly appreciated. Been working on this for two days.
