No login methods supported with using IMAP for incoming email

Question

Hello Support,

I have encountered the below error when trying to use IMAP for incoming email. There is no issue with my email server as I am able to connect to it using a 3rd party mail client. According to my finding from the forum, I suspect it is related to using plain text authentication. However, I am using a docker version of Jira and require some help on enabling plain text authentication.

Thanks

Kelvin

Unfortunately no connection was possible. Review the errors below and rectify:

* ProtocolException: No login methods supported!

I had that problem like a year ago. Checking my notes, I followed this

I hope that helps you.

Hi @Gustavo Félix , Yes I did. In fact I tried both specifying and not specifying any port number; neither of them work.
