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:
Name: www.google.com
Address: 74.125.239.112
Name: www.google.com
Address: 74.125.239.114
Name: www.google.com
Address: 74.125.239.113
Name: www.google.com
Address: 74.125.239.116
Name: www.google.com
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.
