At first, thank you, Zimbra people, for good work and continous efforts... :-)
Congrats for your business victory! Ummm...
My OpenSource Zimbra installation (4.5.3 GA) works on client OSX Tiger (10.4.9) installation for 6 months.
I have ~ 30 accounts, exchanging ~300 e-mails every day.
Several accounts grow on size over 1 Gb now, but Zimbra and PPC G4 coping with it quite OK.
(Machine - Mac G4 700 MHz, 1.25 Gb RAM, 120 Gb HD, directly connected to internet)
There are no big issues with workflow, only few - sometimes logger stops working by itself, but server continues normally, and thats all... EXCEPT:
Just SOME other MTAs is returning/not accepting mail from my Zimbra because on wrong/not qualified HOSTNAME.
I have static IP and FQDN both for "mail.mydomain.com" and "webmail. mydomain.com".
(Notice: I choose name "webmail" because I felt it good for my purpose and then registered that name "webmail.mydomain.com" with my TLD. In this way I got address "webmail.mydomain.com" pointing to my machine for user access to webmail interface).
My HOSTS file:
When I installed Zimbra, I found that ONLY way to get Zimbra installation working is to set OSX Computer Name to "webmail", NOT "mail.mydomain.com", webmail.mydomain.com" or just "mydomain.com". When I set Computer Name to other than "webmail", installation never succeeded. I don't remember exact reasons but there was issues about LDAP not finding localhost and something like.
# Host Database
# localhost is used to configure the loopback interface
# when the system is booting. Do not change this entry.
xx.xx.xxx.xxx webmail.mydomain.com webmail
OSX, as always, automagically adds .local to Computer Name.
So, I notice in logs that Postfix manifests to outside world as "webmail.local". And this is not good.
And I see that it is problem here:
--sample from returned mail--
--end of sample--

Is there any way to tell Zimbra Postfix to use FQDN when talking to other mailservers?
As I see, only few MTAs checks this now, because my server succesfully exchanges mails with LOT of servers on internet without problems for almost half-year, but some mails fail...
