i have given up on Incredimail. I can only get it to receive mail if I use the command from the right click menu from the taskbar icon. I cannot get it to send mail at all, I have lost count of the number of times I have uninstalled and reinstalled. Back to Outlook! (Which works perfectly.)
Incredimail is back on line. Part of the problem was Avast rejecting the certificate. Once I had told it to accept, things improved, but I still feel this was only part of the problem.
I use tesco.net, and gmail, so no problem there.
