Sending mail to non local host(but the host is on same domain)

Hi all!

Ispconfig works great.....but sending mail to users in my own domain does not work since the mx for this particular host is remote but ispconfig keep adding it to /etc/postfix/local-host-names.

- my ispconfig server is ns.domain.se
- Dns is handled elsewhere, mx points to other server.
- i have checked "remote mailserver" for site ns.domain.se
and other sites/subdomains on this domain.

If i remove all domain.se related entries /etc/postfix/local-host-names
it works sending mail to domain.se but if i don't.... => "Recipient address rejected: User unknown in local recipient table;"

ispconfig keeps adding to /etc/postfix/local-host-names and it seems that
other mail failswhen removing some entries from the file.

in /etc/hosts: 127.0.0.1 localhost.localdomain localhost only

in /etc/postfix/local-host-names:

localhost
ns.domain.se (the site use external mail)
localhost.ns.domain.se
localhost.domain.se
localhost.localdomain
www.somedomain1.se (the site use internal mail)
www.somedomain2.se (the site use internal mail)
www.somedomain3.se (the site use internal mail)

Relaying from my own subnet is allowed through $mynetworks.

I must be missing something trivial no?

Thank you.

 

forgot. i am running 2.2.23 on fc8

 

Hi! Double checked. No co-domains anywhere BUT i have several subdomains
such as

d1.domain.se
d2.domain.se
test.domain.se

etc.

They are all set to external mailserver.

Still in local-host-names
ns.domain.se appears. Granted it IS the name of this host and it is a host in the domain.se but mail should be handled elsewhere.

The other subdmomains of this domain does not appear in local-host-names so i guess that works. It seems it appears just because it is the actual hostname of this ispconfig server. i.e
"# hostname"
gives
"ns.domain.se"

More to check?
Thanks!

 

That is the problem. You should use another domain for the hostname, a domain that you don't use for web sites and emails.

 

Too bad. It is a perfectly logical setup.

No way to configure postfix to force all mails for domain.se to external mail regardless of everything else?

Thanks.

 

It's possible if you fiddle with external mailserver settings for all your co-domains and the actual site.

 

I am having the same problem. I tried setting the mailserver to external (co-domains as well), but then I get Relay Access Denied when I try to send an email to any domain hosted at our server. Is there not any way to keep ISPConfig from writing certain domains to the local-host-names file?

 

well as i know now that only works if your actual server hostname is NOT in the same domain as the external mailserver. Because if it is...it will turn up in local-host-names no matter what. sorry. could be fixed by either changing hostname or configuring postfix manually...i don't know enough to do the latter. ideas?

 

Okay, i was misunderstanding exactly what setting mailserver to external does. I now see that keeps domains from being written to local-host-names.

This solved the problem if I use roundcube (installed through ISPConfig). However, if I check "My Server Requires SMTP Authentication" in Outlook, I keep getting a pop up for the username/password everytime I do a send/receive. I don't get this if I don't check the SMTP Authentication box, but then I get a relay access denied everytime I try to send email. Is this an issue with the ISP or some setting on my server?

This is only the second server I have set up, so please forgive me if I'm just overlooking something obvious.

Thanks!

 

What's in your mail log when this happens?

I ran "apt-get purge postfix libsasl2-2 sasl2-bin libsasl2-modules procmail", then followed the steps on page 5 of The perfect Server for Ubuntu 8.10 (Postfix With SMTP-AUTH And TLS). I created a test site in ispconfig and set up an email account, but now I can't log in to roundcube or send/receive in Outlook. I keep getting authentication failure. Here is what the log says.

I've disable the webID_ prefix, so the username should just be whatever i set it to. This is how it was working before I reinstalled postfix. I can still log into roundcube with email accounts that were set up before the reinstall, but it seems that it's not picking up any accounts I've added since then.

 

pop3 is the same as roundcube. it works with accounts setup before reinstalling postfix but not after

 

Yes, they also show up in /etc/postfix/virtusertable
