Hi,

i am struggling with the setup of Horde, active sync and postfix.

I managed to log in with active sync from my iphone. I can retriev mails. it seems to work great. I just can‘t get the mail sending to work with ios. In my mail logs I have always this entry:


=====
Mar 20 13:17:02 midgard-forum postfix/smtpd[20235]: NOQUEUE: reject: RCPT from localhost.localdomain[::1]: 454 4.7.1 <[email protected]>: Relay access denied; from=<[email protected]>

Any idea what is wrong? I‘ve been reading a lit of suggestion across the net, but everything they mentioned does not work.

My postconf -n looks like this:

Hello,
your emails seems to be reject by gmail because some configuration are not correct for a mail server.

- Your server hostname have to be a FQDN (Fully qualified domain name) like server.yourdomain.tld and not only yourdomain.tld
- You have to set the server hostname as reverse DNS on your server IP (in the panel of your hosting provider)
- Have you set all the proper DNS records to send emails ? You can look on iRedmail documentation which explain very well each DNS records to use on a mail server : Setup DNS records for your iRedMail server (A, PTR, MX, SPF, DKIM)
- I have recommend you to use only IPv4 to send emails. Just edit the line inet_protocols and replace all by ipv4 like this :
Code: 
inet_protocols = ipv4
 
Thank you for your answer.

But it is not gmail which is rejecting the mail. The Connection itself is rejected by postfix on my server. The mailserver itself works fine. I can send mail i can get mails. POP3 works, IMAP, SMTP ...

The only Problem is, when I try to log in via active sync. Active sync works for Calendars, incoming mails, address book ... Just not for sending mails.

I triied your sugestion inet_protocols = ipv4. It only changes the error message to: [...] localhost.localdomain[::1]

According to the documentations I found spreaded accross net, it is because postfix does not allow the Connection, but:

mydestination = localhost.$mydomain, localhost, localhost.localdomain
relay_domains = $mydestination

should do the trick. I guess there is a different Setting (maybe mynetworks).
 
I changed the reverse dns entry and my Server Name, all still works well, beside that silly Connection to send mails.
 
I've found the guilty one. I had to set this:

mynetworks = 127.0.0.0/8 [::1]/128 46.4.105.107 [2a01:4f8:141:1c7::2]

Now it works just fine.
