IMAP Config Failure

[Bobber]

When I try to set up an email account, the smtp works but imap does not. I get failure for port 993 for ssl or tls. The tls setting tries for a while but then shows error 500 cannot read. I have also tried using port 143 with TLS but that fails immediately. On my mail server it doesn't appear that there is any attempt to connect. Any ideas what is going on?

Hi Bobber,

To get more details, please provide the EspoCRM error log and screenshot of the IMAP configuration. What IMAP server do you use?

Did you try port 143?

Port 143 fails immediately. It should be STARTTLS for 143 but that is not an option.
