Topic: Problems sending internal mail and mail to outside

==== Required information ====
- iRedMail version: 0.8.3
- Store mail accounts in which backend (LDAP/MySQL/PGSQL):  MySQL
- Linux/BSD distribution name and version:  Ubuntu 12.04 LTS
- Related log if you're reporting an issue:
====

I have instaled iRedMail on a FRESH, working Ubuntu 12.04 LTS version.
I have installed iRedMail 0.8.3 without no problems during the installation.
I have access to admin it via web from the other computers of the network.
Until here everything is OK.

I have a network with various (20) windows pc, all of them with their mail accounts configured on Thunderbird (2 different domains).
I have the mail service contracted with an external enterprise but want to send it all by postfix with iRedMail and test it to probably buy iRedMail-pro.

I have registered the 2 different domains that I use and registered one user on each one to test the system.
I have some problems with the mail sending system and I don't know how to solve them:
    - The mails sent between these two users are accessible by roundcube but do not arrive in their thunderbird accounts (for incoming mails I initially want to continue using the external contracted service)
    - These 2 users cannot send mails to the other users of the network (Recipient address rejected: User unknown in virtual mailbox table)
    - These 2 users cannot send mails to outside directions containing the symbol "-" in the domain (Recipient address rejected: Domain not found)

Re: Problems sending internal mail and mail to outside

If you have mail domain "example.com" hosted on your server, all emails sent to "@example.com" will be delivered locally. So i suggest you add two fake mail domains for testing.

These 2 users cannot send mails to outside directions containing the symbol "-" in the domain (Recipient address rejected: Domain not found)

Is this domain available while you perform DNS query? e.g.

# nslookup your-domain.com

Re: Problems sending internal mail and mail to outside

Hello ZhangHuangbin and thanks a lot for your quick reply.
I have the two domains added for testing.
I unnderstand that the mails between the domains added are delivered locally.

The result for "nslookup my-domain.com" is:
Server: 8.8.8.8
Address: 8.8.8.8#53

Non-authoritative answer:
Name: my-domain.com
Address: 212.142.144.10
Name: my-domanin.com
Address: 212.142.144.9

I have solved the prolblem adding the 2 google dns directions on /etc/resolv.conf

But the main problem (send mail to outside) is still ocurring.
When I send a mail to outside I receive this answer:

"<maildir@maildomain.com>: host mail.domain.es[194.30.0.71] said: 550 5.1.8
    <myiredmailuser@myiredmaildomain.com>: Sender address rejected: Domain not found (in
    reply to RCPT TO command)"

Seems Postfix cannot find recipient domain (maildomain.com in your case).

Can this type of sending be skipped by using a relay or a similar way?
What I want to test is to send a mail with the default user postmaster@mydomain.com to one of the accounts that already exists (contracted with an external enterprise ) with the same domain, for example gistek@mydomain.com
When I try to do it the program says me that the user gistek@mydomain.com does not exists (because I have not created it) and if I create it the mail is sent locally.

Seems Postfix cannot find recipient domain (maildomain.com in your case).

The problem is that the destination domain does not recognize the fake domain I have created to test so it does not accept the mail. Is there any way to solve this error (ussing a relay or similar)?

Re: Problems sending internal mail and mail to outside

Is it possible for you to use a non-existing domain for testing?

Yes I can create a domain @test.com; but when I have tried to send with a non existing domain the receiver rejects it indicating that the sender domain is unknown.

Re: Problems sending internal mail and mail to outside

I have tried to use the test domain i have added in iRedMail to send a mail from one of my real mail accounts (with the user and password from de iRedMail account) and I receive this message.

Error 553 "realaccount@myrealdomain.com" sender address rejected: not owned by user "postmaster@mytestiRedMaildomain.com"

How can I resolve this too?

Re: Problems sending internal mail and mail to outside

Hello,

#transport_maps = proxy:mysql:/etc/postfix/mysql/transport_maps_user.cf
#virtual_mailbox_domains = proxy:mysql:/etc/postfix/mysql/virtual_mailbox_domains.cf
#virtual_mailbox_maps = proxy:mysql:/etc/postfix/mysql/virtual_mailbox_maps.cf
#virtual_alias_maps = proxy:mysql:/etc/postfix/mysql/virtual_alias_maps.cf, proxy:mysql:/etc/postfix/mysql/domain_alias_maps.cf, proxy:mysql:/etc/postfix/mysql/catchall_maps.cf, proxy:mysql:/etc/postfix/mysql/domain_alias_catchall_maps.cf
#sender_bcc_maps = proxy:mysql:/etc/postfix/mysql/sender_bcc_maps_user.cf, proxy:mysql:/etc/postfix/mysql/sender_bcc_maps_domain.cf
#recipient_bcc_maps = proxy:mysql:/etc/postfix/mysql/recipient_bcc_maps_user.cf, proxy:mysql:/etc/postfix/mysql/recipient_bcc_maps_domain.cf


I commented these lines, as i have no use of it. Its sending mail out from my intranet to internet (other network) for same domain.

It's a good idea to search this forum before asking.

Sorry for that!!
I have done what appeared in that topic and that problem I had was solved (I have added a question to the topic)
This configuration can resolve the problem and migth work "near" that the way I want the system to work.


I have a network with various (20) windows pc, all of them with their mail accounts (2 different domains) configured on Thunderbird that send internal e-mails and e-mails to outside and receive internal e-mails and mails from outside.
I have the mail service contracted with an external enterprise and what I want is:

1.- Send emails (internal and to outside) from the 2 domains I have by postfix+iRedMail; but only having to modify the thunderbird configuration in each pc to send mails, not to receive the mails (mails recieved by the mail service I have contracted).

2.- Once the point 1 is achieved the next step is to receive all the mails (internal and from outside) by postfix+iRedMail, and configure thunderbird on all pcs to receive the mails from my server.
