You're seeing this error because you have DEBUG = True in your Django settings file. Change that to False, and Django will display a standard 500 page.
Thank you for your reply, it seems that every thing is ok:
$ nslookup mail.pep.co.ir

Server:         10.252.84.50
Address:        10.252.84.50#53

Non-authoritative answer:
Name:   mail.pep.co.ir
Address: 79.175.161.174


and:

$ python manage.py shell

>>> import socket
>>> socket.gethostbyname("mail.pep.co.ir")
'79.175.161.174'

I attach the whole traceback with this reply.thank you.

Can you send the whole traceback?

Name resolution errors indicate an issue with DNS reachability, or a domain name incorrectly entered somewhere. I'm assuming that you are running the shell on the same server that is running your Django instance? You should be able to do the following on the server where Django is running:

$ python manage.py shell
>>> import socket
>>> # checks if name resolution is working at all
>>> socket.gethostbyname('www.google.com')
'74.125.20.105'
>>> # note you may get a different IP address
>>>
>>> # check if your email host value is resolvable
>>> socket.gethostbyname("mail.xxxxxx.ir")
Traceback (most recent call last):
  File "<console>", line 1, in <module>
gaierror: [Errno -5] No address associated with hostname
>>> 

Obviously I received an error here since I used the masked value you provided. You should get an IPv4/IPv6 address back, or an error similar to the one you posted.

You can also do a quick check if you have shell or command prompt access available on your server outside of Python:

$ nslookup www.google.com
Server: 127.0.1.1
Address: 127.0.1.1#53

Non-authoritative answer:
Address: 74.125.239.112
Address: 74.125.239.114
Address: 74.125.239.113
Address: 74.125.239.116
Address: 74.125.239.115

$ nslookup mail.xxxxxx.ir
Server: 127.0.1.1
Address: 127.0.1.1#53

** server can't find mail.xxxxxx.ir: NXDOMAIN

An NXDOMAIN response means that the domain is either typed incorrectly, or just doesn't exist out on the wild Internet (or wherever your DNS server recursively looks for you)

That command should work on Windows and most Linux distributions (some Linux systems include the 'host' command as an alternative if BIND tools are installed). The output may be formatted differently but should provide similar information.

The full traceback for the error will likely be most helpful, though.
