Hi Eric,
I have already searched the dovecot mailing list and found a few
people who complain about this error exclusively with dovecot version
2.3.11.3
It seems a bug has been introduced on the behavior of the AUTH
mechanism. On the mailing list they recommend patching the sources or
upgrading to a later version. That's why I was asking how to upgrade.

hmmm...
pretty much the same I have on my toaster.
This is what is confusing:
"-ERR [AUTH] Unsupported authentication method" and " method=USER"
I've seen failures with 'method=digest-md5' or 'method=cram-md5'
but never user.
Can you ask about this on the Dovecot mailing list and let us know
what they say?

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:

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
