Original GitHub issue: https://github.com/modoboa/modoboa/issues/2213

Impacted versions

OS Type: Ubuntu
OS Version: 20.04 Server x64
Database Type: MySQL
Database version: Ver 15.1 Distrib 10.3.25-MariaDB, for debian-linux-gnu (x86_64) using readline 5.2
Modoboa: 1.17.0
installer used: Yes
Webserver: Nginx

Steps to reproduce

I'm not sure how to reproduce this, but evidently it is a bug.

Current behavior

When clicking on "Webmail" from the main Modoboa interface, it comes up with Error: Connection to IMAP server failed: [SSL: WRONG_VERSION_NUMBER] wrong version number (_ssl.c:1123).
This is not expected behaviour, it should bring up the Webmail interface. My email client still works, but Webmail doesn't.

Expected behavior

Webmail should open and this error should not appear.

What would you like to know about the configuration? Like ports for IMAP? Is there a report I can extract for you which'll show you everything you need?

A screenshot of the online configuration page will be fine.

Sorry to be annoying but could you please specify which configuration page? There are 10 different tabs on Modoboa settings, unless you want a screenshot of every single one?

I'm also having this error. It seems to be something wrong with the SSL on the IMAP server. If you have "Use a secure connection" enabled in the "Webmail" section of the config, it displays that error. If you disable it, there isn't an error.
