I am an experienced Exim user and just recently testing Zimbra Open Source, and I am loving it already.
However, I am used to this command whenever I wanted to test email routing in the email server, whether I am testing for the routing of local users, local email addresses and external email addresses:
root@localhost# exim -bt firstname.lastname@example.org email@example.com <-- firstname.lastname@example.org router = localuser, transport = local_delivery root@localhost# exim -bt email@example.com firstname.lastname@example.org router = localuser, transport = local_delivery root@localhost# exim -bt email@example.com router = lookuphost, transport = remote_smtp host mail.remotehost.com [18.104.22.168] MX=0
Got the above cheatsheet years ago from http://bradthemad.org/tech/notes/exim_cheatsheet.php.
How can I do this with Zimbra/Postfix? I am searching everywhere on how to do this, but couldn't found any.
