Mail service on the OS X Server 4.0 works only locally

it seems a fu.. up from the update in my server also the .local appears in my mail settings. But i am able to use mail. all connections are working and mail is flowing. so do not be mislead by the .local in your server app

i am using 3 virtual domains and they seem to work as they should

I am having the same problem.

Everything worked fine before upgrading my mac mini to Yosemite and Server App 4.0.

Fetchmail shows the messages being forwarded to the accounts but no messages show up when I check the accounts using Mail.....

I am having same same issue.
But I have done a clean install with 10.10 and OS X Server 4.0.
The error occurred every where. The Websites, Wiki, Mail, etc.
After playing little bit around the other services work now fine, only the mail service is still listening only on local.
No idea why?

A couple of things happen during the upgrade: Your domain name changes, and you have to go back and fix it; and there is a display bug where services are listed as using server.local instead of server.example.com. This is a known bug, I reported it to Apple during beta, and I am not sure why it persists. However, although the display is wrong, try this to verify settings:

Go into Terminal and type: sudo serveradmin settings mail

That will list all of the settings for your mail server. Using serveradmin versus the Server.app might be a better way to manage some of the more advanced settings. You can get more information about serveradmin by typing: man serveradmin

These values are important:

mail:postfix:host_whitelist:_array_index:0 = "ns.100greenwood.net"

mail:postfix:host_whitelist:_array_index:1 = "mail.100greenwood.net"

mail:postfix:domains:_array_index:0:name = "100greenwood.net"

.

.

.

mail:postfix:mydomain = "100greenwood.net"

mail:postfix:enable_list_server = yes

mail:postfix:mydestination:_array_index:0 = "localhost"

mail:postfix:mydestination:_array_index:1 = "$mydomain"

Also in Terminal, type: hostname

That should show you the name of your host. Then type this command: sudo changeip -checkhostname

It should give you a result of: dirserv:success = "success"

If it doesn't then you have a hostname issue. The section above that refers to mail:postfix:mydestination:_array_index:0 = "localhost" uses the variable localhost to find your local server. If there is a name mismatch between them, bad things will happen. Make sure you change everything to the Internet (not the *.local) address so it routes properly.

Ok, This looks similar to the problem I am having. I was only able to send and receive email through the SMTP server if the destination address was a virtual domain. Any email going to the primary server domain rejected all incoming emails. I tried turning off all greylisting and spam filtering, etc to no avail.

I was finally able to get it to work for the primary domain by editing:

/Library/Server/Mail/Config/postfix/main.cf

I had to COMMENT OUT the following line as so:

#smtpd_require_virtual_map = yes

I assume you could also just set the value to no.

I could not find any documentation via a google search on this particular postfix setting "smtpd_require_virtual_map". And with that I am not sure if this is the correct way to fix the problem. There may be a better way to fix this problem and if so I would like to know it.

Ok my suggesting above only works for "real" accounts on the primary domain of the server. If you are using any virtual email addresses on the primary domain this doesn't work. Virtual email addresses on the primary domain are still a problem. virtual email addresses on Virtual domains work fine.

kedmans13 did you get your system to work? I am still struggling with this.

I am having same same issue.

Somebody found a workaround ?

I read this post Configure postfix to accept inbound mail only from Google

and my problem is done !

Thanks !

Warning... My /Library/Server/Mail/Config/postfix/main.cf had mynetworks line twice. Delete one and configure correctly the others.
