I remember the times when ISP support personnel knew the mechanics of mail transfer. It seems, however, that these times are gone forever - every time I call Bell Sympatico Support, I have to spend more and more time explaining what went wrong and most of the time end up working around problems on my end.
About a couple of weeks ago I started having problems with mail messages sent in non-Latin encodings - all non-Latin characters would be replaced with question marks. At first, I suspected Outlook Express, which hasn't been updated for a while and now is discontinued by Microsoft, but trying different mail clients indicated that the problem was with the Bell's POP3 server.
