Exim4 uses remote SMTP to deliver to @mydomain.com even though mydomain.com is in /etc/mailname

http://serverfault.com – As described in the title. If mydomain.com is THE local domain, why would exim attempt delivering mail by contacting it, rather than just storing it in a local mbox? I.e. when I do echo hello | mail root, it sends an email to root@mydomain.com by contacting an MX listed in mydomain.com. The configs are the default Debian stable. Incidentally, this behavior is what I actually want, as mydomain.com uses Google Apps, so I want all mail to be delivered to an MX listed there, but I also want a server of mine to behave like it's its own name too (i.e. its locally sent mail should be from @mydomain.

Stories similar to Exim4 uses remote SMTP to deliver to @mydomain.com even though mydomain.com is in /etc/mailname

I've got an Ubuntu server with the hostname node1.mydomain.com. I have mydomain.com set up with Google Apps for email, and mail sent to node1.mydomain.com arrives in the correct Google Apps mailbox. However, mail sent from this server through sendmail (by cron, php, or whatever else) to node1.mydomain.com only gets delivered locally to the user's mailbox, and isn't sent out over SMTP.

I'm using vps server with ubuntu 10.04 when i send email to Gmail it's ok but for Hotmail fails, i check my logs i find this:

Mar 19 18:09:01 mail postfix/smtp[6340]: 8FAF722294: to=<root@mydomain.com>, orig_to=<root>, relay=none, delay=0.09, delays=0.08/0.01/0/0, dsn=5.4.6, status=bounced (mail for mydomain.com loops back to myself)

I look around inforums to find the solution but i

I have an Ubuntu server running postfix. It is not the mail server for my domain.

Whenever a cron job runs for root, the output is sent to root@mydomain.com (that is, mail is not delivered locally, but sent to mydomain.com's mail server).

I have postfix and mail installed on my server.

The following command works fine

$mail aj@xyz.com

But if I use this command

$mail aj@mydomain.com

The system thinks I am trying to send a local email to the user 'aj'.

Change nameserver 38 weeks 4 days ago

I changed my nameservers at my domain registrar. I waited and not work.

in /etc/hosts:

host1.mydomain.it xx.xx.xx.88

in /etc/nameserverips:

xx.xx.xx.214=ns2.mydomain.it xx.xx.xx.88=ns1.mydomain.it

in /cat/domain/mydomain.it.db:

mydomain.it. 86400 in SOA ns1.mydomain.it. info.domain.it.

According to the manual, if a mail is sent without domain information, it will append $myorigin .

mydomain.com works fine. www.mydomain.com gives "404 - File or directory not found."

I don't want people to use www.mydomain.com instead of mydomain.com, but I also don't want the 404 error in their face if the do.

Ok, so here's my problem: I've set up myself a virtualhost with an appropriate server name. I also have, for example, Squirrelmail and SVN installed on the same machine. I want to get to the default page by typing http :// mydomain , get to my mail frontend by typing http ://mydomain /mail and to my svn by typing http :// mydomain.no-ip.org /svn.

I just got a VPS. All the host gave me was an IP address to have the domain point to.

Lets say my domain is mydomain.com

So what I did was I removed the nameserver (not the NS records, but the actual nameserver) values.
