Thunderbird Events - Organizer has default domain of @internal

When I create a new event by right-clicking on a day on the monthly calendar and then "Invite Attendees" I see in the new pop-up dialog that the organizer of the event has the illegal domain address of "@internal". The attendees receive their invitations but the .ics contains the line

ORGANIZER;PARTSTAT=NEEDS-ACTION;CUTYPE=INDIVIDUAL;SENT-BY="mailto: 

<redacted>":mailto:<redacted>@internal

Since <redacted>@internal is an illegal email address the attendee cannot respond to the invitation either in the affirmative or negative.

How can I change the default domain of the organizer to the email address of the user creating the event? I have searched through all the settings I can find no mention of @internal there or in the documentation on the web.

I have been testing on my Win 8.1 system and Thunderbird 115.16.2 (32-bit), which is the most advanced available. The people I work with experience the same behavior with Thunderbird 128.3.0 on Win 10 and Win 11.

I've figured this out. The problem's source does not lie in Thunderbird's calendar but back in the Cyrus-Imap software for storing email and calendars. When setting up calendars in that software you need to have the line "virtdomains: userid" in your /etc/imapd.conf. When doing that the default domain name is "internal" which does not seem to be very useful.

To get a useful default, also add a "defaultdomain: mydomain.com" to the configuration file, with "mydomain.com" replaced by your domain name. After making this change you need to restart the imap daemon and restart every instance of Thunderbird.

Helpful?
