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.

Hi,
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 2.3.11.3
Any suggestions are welcome
