postfix? sendmail? where does the problem come from? The following message appears in the SquirrelMail interface, when trying to send a message: Server replied: 78 Can't execute command '/usr/sbin/sendmail -i -t [email protected]'. ISPConfig 3.0.2.2 installed on CentOS 5.4 using this perfect server guide. Additionally, when doing a ehlo localhost from port 25, it gives: Code: ?Invalid command The sendmail service is stopped, and the postfix is started. Output of postconf -n is: Code: alias_database = hash:/etc/aliases alias_maps = hash:/etc/aliases command_directory = /usr/sbin config_directory = /etc/postfix daemon_directory = /usr/libexec/postfix debug_peer_level = 2 html_directory = no inet_interfaces = all mail_owner = postfix mailq_path = /usr/bin/mailq.postfix manpage_directory = /usr/share/man mydestination = $myhostname, localhost.$mydomain, localhost newaliases_path = /usr/bin/newaliases.postfix queue_directory = /var/spool/postfix readme_directory = /usr/share/doc/postfix-2.3.3/README_FILES sample_directory = /usr/share/doc/postfix-2.3.3/samples sendmail_path = /usr/sbin/sendmail.postfix setgid_group = postdrop unknown_local_recipient_reject_code = 550 I didn't touch any of the initial definitions, and did only what the guide ordered. Any clue? Thanks! Dotan
That's the 1st thing I do after installing a CentOS system Thanks Falko! Eventually, after hitting a solid brick wall with this issue, I've moved on to a different system. It seems weird to me, that after going through the guide, one step after the other, there are such basic things that don't work as-is. It's too bad, since I really liked the system. Thank you nonetheless! Dotan
too late for Dotan, but had a similar problem. Answer was to amend config.php to sendmail.postfix steps are : >cd /usr/share/squirrelmail/config >vi config.php :s/'/usr/sbin/sendmail'/'/usr/sbin/sendmail.postfix'/g I didn't replace syntax, but easy enough to go to line and amend setting in VI. maybe helps someone else if they hit this.
