HELO! I've tried to configure postfix to relay mail from the hosts on the local network to the outside world. In my case the server host is 192.168.50.9 and the host that originates the mail is 192.168.50.14
When I try to send a message from a Mac OS X client using Apple Mail with 192.168.50.9 as SMTP server setting, I get this in the maillog: Nov 10 14:14:41 rh2 postfix/smtpd[6981]: connect from unknown[192.168.50.14] Nov 10 14:14:41 rh2 postfix/smtpd[6981]: lost connection after EHLO from unknown[192.168.50.14] Nov 10 14:14:41 rh2 postfix/smtpd[6981]: disconnect from unknown[192.168.50.14] Nov 10 14:14:41 rh2 postfix/smtpd[6981]: connect from unknown[192.168.50.14] , at which point mail client continues its attempts to send the message, which, according to log (no new entries), is silently ignored by postfix. According to the comments in the main.conf, I have to specify this to allow relay from my local network: mynetworks = 192.168.50.0/24 I do not know yet how to teach my Mac to say EHLO properly (is it necessary?), so I have also added an explicit (although it is a default.): smtpd_helo_required = no Output of postconf -n alias_maps = hash:/etc/aliases command_directory = /usr/sbin config_directory = /etc/postfix daemon_directory = /usr/libexec/postfix inet_interfaces = all mail_owner = postfix mydestination = $myhostname, localhost.$mydomain, localhost mydomain = $myhostname myhostname = rh2.tere.com mynetworks = 192.168.50.0/24 myorigin = $mydomain queue_directory = /var/spool/postfix smtpd_helo_required = no virtual_alias_maps = hash:/etc/postfix/valias virtual_gid_maps = static:5000 virtual_mailbox_base = /var/spool/vmail virtual_mailbox_domains = /etc/postfix/vhosts virtual_mailbox_maps = hash:/etc/postfix/vmaps virtual_uid_maps = static:5000 Mail is sent without issues from the localhost. What am I missing? Thank you.
