I'm trying to help out a friend who has two Macs on a network connected via ADSL to the internet. I should warn you in advance that I'm not a Mac user!).
They've got a really weird problem on one of their machines (a G5 running Tiger 10.4.11). It refuses to display certain web pages, and refuses to download their emails.
They have a domain hosted by me2uweb.com, and use the SMTP and POP servers on their domain for their emails. For some reason, their Mail program simply won't connect to their me2uweb email servers. Interestingly, they also have an email account with BT Internet, and it will get and send emails on that account just fine.
I obviously thought there was something wrong with the account settings in Mail, but they are perfectly correct.
I then discovered that Safari won't display any web pages that are hosted by me2uweb! However, Safari will happily display pages anywhere else on the Web.
I immediately thought that me2uweb.com were blocking their IP address for some reason, but they assure me they are not. In any case, my friends' other Mac, which sits on the very same network behind the very same ADSL router, works perfectly! It will send and receive emails from their me2uweb email servers, it will display web pages from me2uweb-hosted domains as well as everywhere else.
I believe that their router provides their IP address, so if it were blocked by me2uweb it should block both machines.
In summary, one of the Macs on their network refuses to play ball with anything hosted by me2uweb (web pages or email servers), but works fine in all other respects. The other Mac on their network works perfectly, including with me2uweb.
I am completely stumped. Could anyone make any suggestions? Is this a known problem? I'm afraid I'm totally in the dark when it comes to Macs!
