Hi Luvers,
Here is scenario (not for me by the way, but someone else)
Using laptop with Outlook/Win 7 for client. Mail server is Linux Ubuntu 10.10 (due for upgrade to 14.04 soon) - using Postfix+Dovecot.
1. Able to authenticate to server for smtp and pop using wifi at home and using 3G anywhere.
2. Unable to authenticate in workplace office (talking office building not Office software!!)- keeps asking for username and password when using mail.example.com.au in settings for outlook. (substitute for real domain name of course)
3. Able to authenticate as above if using ip number instead, which makes sense, since in office wifi and mail server on same subnet (192.168.1.X)
Hi Daniel I suggest this is not an issue with the server but with the client. My suggestion would be to ping the mail server using the domain name and see if it resolves. It might also be a good idea to run ipconfig /flushdns Cheers Nic
