Hi, Jan. Good to see you here. Thanks for your reply.

Thanks for the observation. I think that explains why when I have a
notification window for a calendar event in Thunderbird and I press a
button in that Window, the Postfix log shows an IMAP access. Something
like this:

Jan 17 12:03:06 mail cyrus/imap[3326]: starttls: TLSv1.2 with cipher
ECDHE-RSA-AES128-GCM-SHA256 (128/128 bits new) no authentication
Jan 17 12:03:06 mail cyrus/imap[3326]: login: localhost [::1] dbareiro
PLAIN+TLS User logged in

By the way, if you have a moment to check the last message I sent in the
thread "Invalid VObject, line 1 did not follow the icalendar / vcard
format" in the Horde list, I would appreciate that. It's my response to
an email from Michael Rubinsky. In case it's helpful, I'm using Horde
Groupware Webmail Edition 5.2.22.

Thanks for your time.

Kind regards,
