We've been running our new Zimbra system for a few days and things seem OK. However, I got a returned email today with this error message:
The Postfix program
... host mxi2s.craigslist.org[22.214.171.124] said:
: Helo command rejected: need fully-qualified hostname (in
reply to RCPT TO command)
If I look in /opt/zimbra/conf and look at main.cf, indeed
myhostname = mail-01
Where is this being set from? Shouldn't the domain name be appended to mail-01 at this point? In the admin GUI, my Service host name is mail-01.
Our email is getting through, but maybe few are checking for the FQ hostname. Even though, I'd like it to be set correctly.
Thx in advance!
