Yes, it will be in 5.2
Thank you! 
Great to hear! 
Is this also fixing smtp with starttls port 587 and plain method? For me the outgoing mail server check fails whereas the imap4 with ssl port 993 amd plain works.
I don’t know what is going on, but I had working IMAP email setup. Around last week it stopped syncing completely. Tried to delete it and re-setup. but it won’t still sync at all. All I got is “Sync. error”. Anybody with ideas what I could try next?
