1 Answer Sorted by: 1 After a whole day of testing, I discovered that this problem happens when one does not run the Virtualmin post-config wizard. In this case, the file /etc/usermin/mailbox/config is left at the default configuration mail_system=4. Changing this to mail_system=1, fixes the problem when using hashed passwords.
Dovecot login processes can check via UNIX socket if the incoming connection should be allowed to log in. This is most importantly implemented to enable TCP wrappers support for Dovecot. TCP wrappers support ¶ You must have built Dovecot with support for TCP wrappers. You can do this by giving –with-libwrap parameter to configure.

Setting pop3_lock_session=yes makes Dovecot lock the mailbox for the whole session. This is also what the POP3 RFC specifies that should be done. If another connection comes while the mailbox is locked, Dovecot waits until the locking times out (2 minutes with Maildir, mbox_lock_timeout with mbox).

Original Message: I have to report a problem with Dovecot & Usermin. The problem affects ONLY domain users (main virtual server users) – all additional users created, can login to Usermin and access emails ok. So when I create a new virtual server called test.com, I click the ‘login to usermin’ button from ‘edit user’.

Jan 11, 2022This essentially tells you that a client tried to connect with an unsupported TLS version. Maybe your server only supports TLSv1.2 and TLSv1.3 but the client tried to connect with TLSv1 or TLSv1.1 or the other way round. To see which TLS versions are configured on your Plesk server run this: # plesk sbin sslmng –show-config.
