Hello Marco, “internal” is the default value of the defaultdomain imapd.conf’s parameter, so changing it might help. Look also at the calendar_user_address_set parameter. Cyrus IMAP sends emails for iCalendar objects, when it recognizes one of the email addresses there as owned by the current user. While there is a default, you can add more email addresses (replace the default) you have with curl -XPROPPATCH -Hcontent-type:application/xml -umm@domain:password --data-binary @- <<EOF https://server/dav/principals/user/mm <propertyupdate xmlns="DAV:" xmlns:c="urn:ietf:params:xml:ns:caldav"> <set> <prop> <c:calendar-user-address-set><href>mailto:m1@domain</href><href>mailto:m2@domain</href></c:calendar-user-address-set> </prop> </set> </propertyupdate> EOF TB should use mm@domain when speaking CalDAV in the Organizer/Attendee/Participant properties.

I am using 3.6.1-4+deb12u3 and Thunderbird for Calendar. If I plan a meeting in the calendar, Cyrus itself (not TB) tries to send from mm@internal to the SMTP server. This will of course intentionally fail. Where is the place to set that address? My username for cyrus is mm without a domain part. In TB I set up my normal IMAP/SMTP account and this account with the proper mail address is selected in the calendar settings. Although, the participant field already includes mm@internal. Is that coming from Cyrus or from TB? ------------------------------------------ Cyrus: Info Permalink: https://cyrus.topicbox.com/groups/info/T005e37dde3985398-Mb43b57e4e466742abae717a8 Delivery options: https://cyrus.topicbox.com/groups/info/subscription
