Since I upgraded to 2.3.4 I have lots of line in logs like these:
Nov 28 17:35:48 buzalum_rhel7 dovecot: imap(iniramgon@mydomain)<udqWKLx7HN/AqAFh>: Error: unlink(/etc/dovecot/virtual/dovecot-acl-list) failed: Read-only file system (in acl-backend-vfile-acllist.c:338)
Nov 28 17:35:48 buzalum_rhel7 dovecot: imap(iniramgon@mydomain)<udqWKLx7HN/AqAFh>: Error: dovecot-acl-list creation failed: safe_mkstemp(/etc/dovecot/virtual/.temp.buzalum_rhel7.6469.) failed: Read-only file system
These lines did not happen with Dovecot 2.3.2.1. doveconf -n output below. I have also tested to create an emty file with userid entrega in /etc/dovecot/virtual/ and works, so it does not seem a problem with permissions. Any idea about this problem?
