My domain is hosted by domainnamesgb.com, which is now part of Legend Communications plc (home of Demon.net). I suppose I could look at moving this to a provider that does offer access to its webservers on an alternate port, but unfortunately I have just renewed the arrangement for two years (although it was working then!).
BTW, from reading around this subject it appears that AOL may for some time have been forcing my outgoing emails through its own SMTP servers, irrespective of the settings in my Outlook account. However the move to ban 'alias' email addresses seems to be more recent and the source of the current problem.
I believe that other providers also do this or similar. Alternate port access for outgoing mail seems to be pretty standard for US providers as many, if not most, of their ISPs seem to block port 25 for the same reasons as AOL.
