can't save imap settings

I change settings to special port, but after saving, it defaults back to “TLS if available”. I also used the diagnostics to fix it. But after closing the accounts window, it resets to “TLS if available”.

Hello,

can I ask what email service provider do you use?

Sbcglobal which is a yahoo account. Also me.com.

Hello,

Yahoo IMAP servers ale in terrible condition, unfortunately until they will repair them
we will not be able to guarantee functionality with them.

please try to update (if you haven’t already) to 5.0.18661.0 as there are introduced some workarounds around Yahoo’s faulty IMAP login servers, but we can’t make more that this at this moment.

regards
Jan
