We are using Sendmail 8.12.8 as our mail server. I have just upgraded my email client from Outlook 2000 to Outlook 2002. Outlook 2002 can not get the messages via POP3. I went back to Outlook express which was still on the same pc and this works fine. I get an "Unknown Error 0x80004002" when trying to get messages.
All options appear to be correct and using the test settings option in Outlook passes.
