I really tried to like the Mail program that ships with the OS - ran it for ~4 months.
I installed Thunderbird last week.
How do I disable pantheon-mail from starting on first login? I thought it might be the notifications settings for mail but they are turned off and I still get pantheon-mail appearing in the dock.
Thunderbird is set to the default mail app in settings -> apps.
Did I miss another setting or do I have to resort to running 'killall pantheon-mail' as a login start script?
[problem migrated from Juno to Hera if it matters]
