    The dovecot version we (qt) compile has the vpopmail driver in it,
    the dovecot repos don't have that driver compiled in. If you use
    the many domain version of qmail toaster that it would be okay,
    but using the stock version then, no, you would run into trouble
    using the dovecot repo versions.

    still having problems, it's safe to update dovecot with this
    guide or I  risk to break something in Toaster setup?

        In my /etc/dovecot/toaster.conf I Have:
        auth_mechanisms = plain login digest-md5 cram-md5

        while the /etc/dovecot/conf.d/10-ssl.conf is the same as
        yours  with :
        ssl = required

        I've found this on the dovecot mailing list :

            Hi everyone,
             I have been having a weird problem connecting pop 3 to
            my corporate server from Outlook and Thunderbird for
            about two weeks.
            When the client tries to connect to the server, I got
            this error message "-ERR [AUTH] Unsupported
            authentication method" and in the Dovecot logs I found
            errors like "pop3-login: Info: Disconnected (tried to
            use unsupported auth mechanism): user=<x...@xxxxxx.it>,
            method=USER, rip=xxx.xxx.xxx.xxx, lip=xxx.xxx.xxx.xxx,
            TLS, session=<bXG42jTVxNtc3/SS>
            " .
            The strange thing is that the same client checks
            multiple boxes on the same domain and not all of them
            give an error, also the error occurs randomly, maybe for
            half a day it is impossible to download the mail and
            then suddenly it works for a couple of hours.
            Using the imap protocol there are no problems.
            When the clients manage to connect I find this in the
            Dovecot logs "pop3-login: Info: Login:
            user=<x...@xxxxxx.it>, method=DIGEST-MD5,
            rip=xxx.xxx.xxx.xxx, lip=xxx.xxx.xxx.xxx, mpid=5510,
            TLS, session=<+0htGDnVWPdc3/SS>", I don't know why on
            the same client without changing anything the method
            switch from USER to DIGEST-MD5
            The server is up to date, dovecot version is

            Any suggestions are welcome
