I had a hard time figuring out that one has to use the format from imap_open to configure the IMAP server, because my server only understands SSL on port 993 and since this produced only a timeout and not a helpful error message, the bug hunting was a bit annoying.
TBH, I was struggling with this myself a couple of times but forgot about it once I got it right. Thanks for pointing this out! Optimally this should also be added to the config page ...
