Paul, the only "problem" i've run into is in regards to a popup window
when using SSL. I used OpenSSL rather than verisign et al. for the
certificates on the mail server. A little finagallig got all the other
clients to be ok with a self-signed certificate, but Some (not all)
userers with the latest version of OE can't seem to get one of the "are
you sure" security popups to go away when using SSL to connect. A post
earlier today might have the solution though.
On your server, take your imapd.pem file and copy the lines between Begin
Certificate and End Certificate to a file, name it <something>.cer. Send it
to your Windows box, right-click, select Install Certificate. I have
self-signed certificates on mine and it works fine. Natch, you'll have to
sign your certs properly and with the right name.
