every time I start up OE I have to go into accounts and revise incoming server details which have been corrupted. pop address becomes localhost and the original pop address has been appended to account name. this must be an esy one......?
The change of the server details, to "local host", is usually caused by an email utility (most commonly an antivirus program), so that the AV program can "intercept" the email before it is donwloaded to or sent from your computer. It doesn't happen with all AV, but it's quite normal.
Unless you're having problems with sending or receiving email, you can leave it alone.
