Mail is sent but not received.

[pietrek]

Hello.

I installed the VestaCP server management package on Ubuntu Server 16.04.
Website works. FTP works. There are problems with mail.
Mail coming out via webmail works - comes out and is delivered.
Incoming mail unfortunately does not work. Mail does not arrive.

What do I need to check ??

Please suggest.

Same issue, I cant recieve mail from other servers, mail from domains within my panel works

[pietrek]

Now I have the situation that after sending an email to the domain configured on VESTACP I get the answer:

Code: Select all

This message was created automatically by mail delivery software.

Hello, can you post you result on this page: https://www.checktls.com/perl/live/TestReceiver.pl
Put some existing email on the server and tell us the results.

Hi I have this same issue, has there been a solution?

I have the same problem, and I think it's SSL certificate problem, something with the vesta panel.

CERT VALIDATION ERROR
EXPIRED Certificate 1 of 1 in chain:

in the test.

Https://www.checktls.com/perl/live/TestReceiver.pl

Does your domain have SSL certificate?

Hi, I do have Let Encrypt but it seems to be fine, this is my TLS out put message I get:

Trying TLS on mail.domain.com.au[m.y.I.P] (10):
seconds test stage and result
[030.034] Cannot connect to server (reason: Connection timed out)

I'm using my domain providers DNS service to point my mx record. can someone confirm how the mx record should look at the moment mine is:

Name Type Priority TTL Address
domain.com.au. mx 10 3600 mail.domain.com.au

When I try to ping mail.domain.com.au from CMD I do get a response.

Ok so after investigating I found that my set up was all correct but on my VPS provider side they had port blocks on their end which I cannot see. They opened the SMTP ports and mail started to flow.

This has taken me a month of rebuilding and researching and questioning my myself even thinking screw it I'll just pay for a mail server. Now everything is working for me, hope the original poster has figured his issue out too if not maybe his VPS provider might have ports blocked too.
