Thank you AKi for the clarification. At least in this rather old dovecot-2.2.36 from CentOS 7 (I know, it needs updating but I have to do what says the one who pays:) using the negative "-te" form did not work. I found in my logs: dovecot: imap(t...@domain.com): Error: Global ACL file /etc/dovecot/global-acls line 1: Unknown ACL '-' and mailbox access was prevented for all users. I used the form * user=t...@domain.com lrwsipk And it seem to work now. Thank you again. _______________________________________________ dovecot mailing list -- dovecot@dovecot.org To unsubscribe send an email to dovecot-le...@dovecot.org
