Sandra and anyone else interested in this thread. A Google search turned up a very similar problem reported by another user of Pegasus Mail but with a firewall other than Webroot Desk Top firewall. Many suggestions were made particularly centred around Winsoc issues, but the eventual solution turned out to be that Zone Alarm had been briefly tried before being uninstalled and replaced by another firewall. The uninstall had left behind a file which sometimes ran and monitored internet traffic and interfered with the POP3 and SMTP processes. The person concerned re- installed Zone Alarm, uninstalled it again, checked that the offending file had actually gone, - no future connection problems! I have never had Zone Alarm on this machine, but I used Sygate for a long time and also tried Kerio briefly. I suspect that remnants of them may be the cause of my problem. At least I feel confident that Webroot Desktop Firewall is not directly involved nor Pegasus Mail.
