Wietse:

thank you for your support. It seems to be a bit better - at least now I can send an email but I can't receive it.

My DNS looks like:
@ 86400 IN MX 10 mail
and I just added:
mail 86400 IN A  888.888.888.888

I disabled the dns lookup.
Then I've tried to send an email from privatem...@mail.de to i...@domain1.de and got this from the log:


Sep 5 09:05:21 nudin1 postfix/smtpd[31096]: warning: dict_nis_init: NIS domain name not set - NIS lookups disabled Sep 5 09:05:21 nudin1 postfix/smtpd[31096]: Anonymous TLS connection established from shout01.mail.de[213.128.888.216]: TLSv1.1 with cipher AECDH-AES256-SHA (256/256 bits) Sep 5 09:05:21 nudin1 postfix/trivial-rewrite[31074]: warning: do not list domain domain1.de in BOTH mydestination and virtual_mailbox_domains Sep 5 09:05:21 nudin1 postfix/smtpd[31096]: 677F412E0063: client=shout01.mail.de[213.128.888.216] Sep 5 09:05:21 nudin1 postfix/cleanup[31092]: 677F412E0063: message-id=<52288189.8040...@mail.de> Sep 5 09:05:23 nudin1 postfix/trivial-rewrite[31074]: warning: do not list domain domain1.de in BOTH mydestination and virtual_mailbox_domains Sep 5 09:05:23 nudin1 postfix/trivial-rewrite[31074]: warning: do not list domain domain1.de in BOTH mydestination and virtual_mailbox_domains Sep 5 09:05:23 nudin1 postfix/local[31094]: DBCDD12E0065: to=<i...@domain1.de>, relay=local, delay=0.03, delays=0.01/0/0/0.02, dsn=5.1.1, status=bounced (unknown user: "info") Sep 5 09:05:23 nudin1 postfix/smtp[31102]: 677F412E0063: to=<i...@domain1.de>, relay=127.0.0.1[127.0.0.1]:10024, delay=2.6, delays=0.15/0.01/0/2.4, dsn=2.0.0, status=sent (250 2.0.0 from MTA([127.0.0.1]:10025): 250 2.0.0 Ok: queued as DBCDD12E0065) Sep 5 09:05:54 nudin1 postfix/smtp[31076]: connect to mail.de[2001:868:100:600::200]:25: Connection timed out Sep 5 09:05:56 nudin1 dovecot: pop3-login: Login: user=<i...@domain1.de>, method=PLAIN, rip=221.172.223.1, lip=888.236.10.239, mpid=31110, TLS Sep 5 09:05:58 nudin1 dovecot: pop3(i...@domain1.de): Disconnected: Logged out top=0/0, retr=0/0, del=0/3, size=5904741

First the sending process and then the fetching one.

I just see:
postfix/trivial-rewrite[31074]: warning: do not list domain domain1.de in BOTH mydestination and virtual_mailbox_domains and I changed it already in main.cf to nudin1 (it's just a name for the server I came up with, but the domain isn't registered).

Not sure how to continue from here. :-S

Hope anyone can help me to get this up and running.

Thanks,
Chris

Hello,

I've setup Postfix, Dovecot with MySQL and PostfixAdmin like here:
https://www.exratione.com/2012/05/a-mailserver-on-ubuntu-1204-postfix-dovecot-mysql/
on an Ubuntu 12.04 VPS.

I can send mails - so far so good.
Now I assume, that something is wrong with my rejection list. If I send
an email from a freemailer to any account I see this in the mail.info:

Sep  5 04:47:01 nudin1 postfix/smtp[26753]: 5F08712E005F:
to=<root@nudin1>, relay=none, delay=0.05, delays=0.01/0/0.04/0,
dsn=5.4.4, status=bounced (Host or domain name not found. Name service
error for name=nudin1 type=AAAA: Host not found)

Postfix requires that the destination has an MX, A, or AAAA record.

To disable DNS lookups:

# postconf -e 'disable_dns_lookups = yes'
# postfix reload
