I have a dovecote postfix setup and locally I can telnet port 25 send and recieve mail. When I try it from an external machine it just hangs there waiting.

postconf -n gives me...

alias_database = hash:/etc/aliases
alias_maps = hash:/etc/aliases
append_dot_mydomain = no
biff = no
config_directory = /etc/postfix
luser_relay = corcoraj
mailbox_size_limit = 0
mydestination = jcorcoran.net, li33-170.members.linode.com, localhost.members.linode.com, localhost
myhostname = mail.jcorcoran.net
mynetworks_style = host
myorigin = /etc/mailname
readme_directory = no
recipient_delimiter = +
smtp_tls_session_cache_database = btree:${data_directory}/smtp_scache
smtpd_banner = $myhostname ESMTP $mail_name (Ubuntu)
smtpd_recipient_restrictions = permit_mynetworks permit_sasl_authenticated reject_unauth_destination
smtpd_tls_cert_file = /etc/ssl/certs/ssl-cert-snakeoil.pem
smtpd_tls_key_file = /etc/ssl/private/ssl-cert-snakeoil.key
smtpd_tls_session_cache_database = btree:${data_directory}/smtpd_scache
smtpd_use_tls = yes
virtual_alias_maps = hash:/etc/postfix/virtual


I have tried this from different machines so I do not think it is a firewall issue.

Any pointers?

Thanks,
Jason.

I can connect to it on port 25. Perhaps the host you are checking from has port 25 outgoing blocked?

Thanks,

Seems the 2 different networks I checked from where blocking port 25. Went to an internet cafe and all is good.


Thanks again.

Jason
