Can you check two things?
I don’t know (sorry) so I’ve changed it back to pop3.britishlibrary.net, which is how it was before I started meddling!! It now looks like this:
[MailScanner]
DefaultPopServer=pop3.britishlibrary.net
DefaultSmtpServer=pop3.britishlibrary.net
ShowTrayIcon=1
UseDefaultSmtp=0
AutoSetProtection=0
I’ve returned MSGTag & Outlook Express to pre-Avast and then run the Mail Protection Wizard.
I was then unable to send any mail so I removed the Requires Authenitcation tick from OE and can now send from all accounts, tag the mail and scan all inbound mail. At present the only thing I can’t do is scan outgoing.
