Hey people, on Tuesday 2020-12-01 we'll migrate our mail server again.

This time we'll change the following: - disable IMAP on Port 143 - disable POP3 on Port 110 - enable SMTPS on Port 465

Note: IMAPS (993), POP3S (995) and Submission (587) is not going away with this change. Please check your setup, that it's not using either Port 110 nor 143.

For the future, there are plans to deprecate Submission port 587, so feel free to use port 465 asap.

Best regards, Frederik

Migration done. Please check your SMTP setup to use Port 465 to not run into issues with migrations in the future. Frederik
