Topic: [SOLVED] External Recipient Adresses getting rejected

Hi,

i installed iRedMail on an Ubuntu 10.04 LTS.
It works like a charm with local delivery (two local testdomains with testaccounts).
But when it comes to sending Email to external domains they get rejected.
I cant receive or send emails to external domains. On the Client Side (Thunderbird)
i get a 5.1.1 Error : Recipient address rejected.

In Detail thats what postfix says (smtp verbose mode) :

external domain : makant.de
internal domain : reekin.net

I tried to remove totally the recipient checks in postfix, but it didnt worked out.
I also did MX and SPF entries for the domain. Nothing worked out.
After three days of google and readin this forum i hope i can find by writing this post.

Thx in advance

Re: [SOLVED] External Recipient Adresses getting rejected

I'm a little confused.

You sent mail to "m.wolf@ makant.de", but postfix can't find either catch-all account or the certain account:

maps_find: virtual_alias_maps: @makant.de: not found
mail_addr_find: m.wolf@makant.de -> (not found)

Seems domain "makant.de" is hosted on your iRedMail server, isn't it? If so, what does your "external domain" mean?

Re: [SOLVED] External Recipient Adresses getting rejected

Sorry i try to explain better.
I got two root server.

Server A is a live system with a qmail toolchain and currently in use with the domain : makant.de (this server works)
Server B is a testsystem where i test the iredmail with the domains : reekin.net and rekin.de.

On server B i can send mail between both domains (which means local delivery cause they are on the same machine).
But when i try to send from the testsystem to Server A (or any other external domain) email then it gets rejected.
Also when i try to send email from external systems to the to domains on the testsystem they get rejected.

Can you post related postfix log in iRedMail side? And error log in returned notify mail which sent from external domain?

Re: [SOLVED] External Recipient Adresses getting rejected

Can you try to turn off postfix debug mode, then send a test mail with 'mail' command from command line directly, and paste terminal output message here?

# echo 'mail body' | mail - s 'subject' user@external_domain.com && tail -0f /var/log/mail.log

It simply send a test mail to external user, and track log in postfix log file.

Testmail from Livesystem (makant.de) to Testsystem (reekin.net)

failure notice to m.wolf@makant.de

Hi. This is the qmail-send program at makant.de.
I'm afraid I wasn't able to deliver your message to the following addresses.
This is a permanent error; I've given up. Sorry it didn't work out.

Re: [SOLVED] External Recipient Adresses getting rejected

to=<test@reekin>, relay=none,

It's strange that it shows relay=none.

Did you change postfix setting? such as transport.

Re: [SOLVED] External Recipient Adresses getting rejected

default_transport = error
relay_transport = error

I see you have these two in postfix main.cf, why did you change defaule value to 'error'? And what does 'error' means?

Can you try to change then back to postfix default values? You can find them in output of command 'postconf -d'.

Thanx a lot Zhang,

correcting default_transport = smtp and relay_transport = relay (postfix defaults) did it.
I was so focused on recipient restrictions that i didnt see this. (And to be honest last time i worked
with postfix was 2003 smile)

I cant explain how this values changed to error. One point is that first install of iredmail was uncompleted as i lost
my ssh session to the server. Did then several reinstalls (one time mysql one time ldap) but i cant tell how this
values changed.

Thanx a lot. You made my day.
