Hi everyone,
I’m having an issue with Mailcow when trying to configure Thunderbird.
When I set up my mailbox in Thunderbird, the IMAP connection fails with a certificate error. Instead of using the correct certificate for mail.example.com, Thunderbird (and now even web access) seems to be presenting the certificate for autoconfig.example.com.
This causes Thunderbird to reject the connection, and the same certificate mismatch issue is now happening on the web interface as well.
Has anyone else experienced this? Is there a way to force Mailcow to always use the certificate for mail.example.com instead of autoconfig.example.com?
Any help or hints would be greatly appreciated.
Thanks in advance!
