We'll need a look at your configuration (dovecot -n).

Hello, I'm new to dovecot and greet everyone! I come from courier-imap and updated my imap server now to dovecot-2.4.2. All user directories and files were copied 1:1. In some cases, I now receive the following message in logfiles:

If I filter for "Panic" now I see: 2025-11-28 15:20:52.183676628 Nov 28 15:20:52 imap(Email_address_hidden)<2297539><zNQfVqhEx98l90IK>: Panic: file imap-sieve-storage.c: line 216 (imap_sieve_add_mailbox_event): assertion failed: (ismt->src_box == NULL || ismt->src_box == src_box)
Panic repeats up to several times.
In moment of crash I can find lots [# of repeats] of copies of ONE mail file in users .Trash/tmp dir. Original mail file also in e.g. INBOX/cur
Please tell me wht's going on here. I checked all permission, dirs and so on.
