Re: postfix dsn=4.3.0, status=deferred (mail transport unavailable)

Seems you don't have correct transport for this domain. Try this:

cd /etc/postfix/mysql/
for cf in $(ls *cf); do echo $cf; postmap -q "<real-domain-name>" mysql:./$cf; done

Replace the "<real-domain-name>" by your real mail domain name.

Re: postfix dsn=4.3.0, status=deferred (mail transport unavailable)

iRedMail doesn't use "private/amavis" at all.

We just need the output of commands in my previous reply.

Re: postfix dsn=4.3.0, status=deferred (mail transport unavailable)

Sorry I have misunderstood that.
Mails are going out and in when sending from my domain in roundcubemail, to myself.
When I send out to other domain than mail goes out.
But from other domains mails doesn't come in.

Here is a result

catchall_maps.cf
domain_alias_catchall_maps.cf
domain_alias_maps.cf
recipient_bcc_maps_domain.cf
recipient_bcc_maps_user.cf
relay_domains.cf
sender_bcc_maps_domain.cf
sender_bcc_maps_user.cf
sender_dependent_relayhost_maps.cf
sender_login_maps.cf
transport_maps_domain.cf
dovecot
transport_maps_user.cf
virtual_alias_maps.cf
virtual_mailbox_domains.cf
povej.net
virtual_mailbox_maps.cf

Re: postfix dsn=4.3.0, status=deferred (mail transport unavailable)

Your mail domain "povej.net" has 2 MX records in DNS:

$ dig +short -t mx povej.net
10 povej.net.
30 mail.povej.net.

Lowest priority number (10 provj.net) has the highest priority, so all other mail servers will connect to "provj.net".

$ dig +short -t a povej.net
216.239.34.21
194.249.178.190

So all other servers will connect to EITHER 216.239.34.21 OR 194.249.178.190 to deliver email, it's randomly picked up.

If your mail server is "mail.povej.net", you should remove the MX record "10 provj.net".

Re: postfix dsn=4.3.0, status=deferred (mail transport unavailable)

Thank you I have removed wrong IP from MX record.
But still not working.
And don't know what that has to do with mails which are stuck in queue and not going into my mailbox.
I get mails on my server, but from queue to my inbox not.
I have nov 2059 mails waiting in queue.

Re: postfix dsn=4.3.0, status=deferred (mail transport unavailable)

Ok I am now a bit closer to problem.
It is amavis which makes problem I have disabled it in main.cf
#content_filter = amavis:[127.0.0.1]:10026
#smtp-amavis_destination_recipient_limit = 1

and now I can get mails to inbox.
How can I check what is a problem with amavis so that it doesn't work with postfix?
I also tried to change 10026 to 10024 and no changes still not working, when amavis enabled.

Re: postfix dsn=4.3.0, status=deferred (mail transport unavailable)

Ok now I found a solution.
I googled more about this problem
warning: connect to transport private/amavis: No such file or directory

And I found out that I need to change this in main.cf
content_filter = amavis:[127.0.0.1]:10026
to this
content_filter = smtp-amavis:[127.0.0.1]:10024

now works ok

This is WRONG.

*) If port 10026 is not open, please try to restart Amavisd service, because it's part of Amavisd service.
*) Port 10026 is used for outbound emails, and 10024 are used for inbound mails.

content_filter = smtp-amavis:[127.0.0.1]:10026

And also works oK now, thank you
