I can't seem to integrate postfix to my mail client (thunderbird). Webmail is working but how come i can't use it externally???
I tried telnet my.do.main.ip 25 but I can't connect through it.
I'm using CentOS 5.2 Webmin / Virtualmin.
here's my main.cf
queue_directory = /var/spool/postfix command_directory = /usr/sbin daemon_directory = /usr/libexec/postfix mail_owner = postfix inet_interfaces = all unknown_local_recipient_reject_code = 550 alias_maps = hash:/etc/postfix/aliases debugger_command = PATH=/bin:/usr/bin:/usr/local/bin:/usr/X11R6/bin xxgdb $daemon_directory/$process_name $process_id & sleep 5
sendmail_path = /usr/sbin/sendmail.postfix newaliases_path = /usr/bin/newaliases.postfix mailq_path = /usr/bin/mailq.postfix setgid_group = postdrop html_directory = no manpage_directory = /usr/share/man sample_directory = /usr/share/doc/postfix-2.3.3/samples smtpd_sasl_local_domain = smtpd_sasl_auth_enable = yes broken_sasl_auth_clients = yes smtpd_recipient_restrictions = permit_sasl_authenticated permit_mynetworks reject_unauth_destination smtpd_tls_auth_only = no smtp_use_tls = yes smtpd_use_tls = yes smtp_tls_note_starttls_offer = yes smtpd_tls_key_file = /etc/postfix/ssl/smtpd.key smtpd_tls_cert_file = /etc/postfix/ssl/smtpd.crt smtpd_tls_CAfile = /etc/postfix/ssl/cacert.pem smtpd_tls_loglevel = 1 smtpd_tls_received_header = yes smtpd_tls_session_cache_timeout = 3600s tls_random_source = dev:/dev/urandom mail_spool_directory = /var/spool/mail virtual_alias_maps = hash:/etc/postfix/virtual sender_canonical_maps = hash:/etc/postfix/sender_canonical
Any ideas? Please help...
I suspect your setup is working well, and that your ISP may be blocking outgoing port 25 (which is common these days).
One way to solve that would be to use your ISP's port 25 for outgoing email, and connect to your own server for IMAP.
The other possibility would be to enable one of the alternative ports within Postfix -- for example, you could enable SMTPS (465) or Submission (587) and configure Thunderbird to use those instead of the authentication you're using now.
To enable those, log into Virtualmin, click "Webmin" on the top-left, go into Services, then Postfix Mail Server, In there you'll see Server Processes, where you can enable SMTPS or Submission.
Of course, if you have a firewall on your server, you'll have to open up those ports there too.
