I have followed the advice in http://support.apple.com/kb/TS3023 to solve this but the main.cf file keeps reverting back to the original meaning I am having to re-apply this patch this every few hours at the moment.

 

Not sure whether this is happening when I stop and restart mail, reboot or edit some of the other postfix settings as I install roundcube - but it is extremely annoying.  Any ideas?

    The problem isn't at your client, it is at the server...

    The Apple Mail server has four authentication methodes it can use:

    - Kerberos

    - Digest (CRAM-MD5)

    - APOP (POP only)

    - Cleartext

     

    Microsoft Outlook and Outlook Express can't use CRAM-MD5 authentication. The free Mozilla Thunderbird can. The problem is thus not with Apple, but with Microsoft, although I don't think calling Microsoft will help a bit.

     

    You can lower the Mail Server security by allowing the Cleartext authentication method, use Kerberos (better) or limit yourself to POP mail if you wish to use Microsoft products to connect to the Apple Mail server.

    You are likely able to change the authentication method for your outgoing mail on the client, please match that to the mechanism of your incoming mail, which seems to work fine...

    How are your DNS settings in the server app?

    This should be a hint
