I search and found that more ram did fix it for me in the past, I wonder why we

Re: [qmailtoaster] Weird problem on pop3 connection

[Fabio Mecchia]

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.

the dovecot mailing list.

Re: [qmailtoaster] Weird problem on pop3 connection

[Eric Broch]

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?

If you use the many domain version of qmail toaster that it

Re: [qmailtoaster] Weird problem on pop3 connection

[Eric Broch]

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 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=, method=USER, rip=xxx.xxx.xxx.xxx,
lip=xxx.xxx.xxx.xxx, TLS, session=
" .
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=,
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

Hi,
still having problems, it's safe to update dovecot with this guide or I
