Why are you using a self signed? If your machine has an external hostname use lets encrypt to get an SSL cert for it.

I was trying to set up a replacement laptop running W10/64 to replace a Win7 laptop, installed TBird, and, attempted normal setup:
IMAP StartTLS 143, SMTP StartTLS 587 (like on old laptop), and, to cut a long story, eventually discovered it won't work till I changed IMAP SSL/TLS 993 ?
SMTP seems OK, only IMAP didn't (I recall earlier similar type of issues with either Outlook or OE or WLive?)
is this the self certified part ? or what is it ?
what's the best way around ? or just leave it as 993 ?
thanks for any hints , pointers or even words of encouragement
