more relevant info I believe:
a) the only 2 NON-commented lines in /etc/dovecot/conf.d/10-auth.conf are:
auth_mechanisms = plain
!include auth-system.conf.ext
b) and in /etc/dovecot/toaster.conf:
#grep -v "#" toaster.conf
auth_cache_size = 32M
auth_mechanisms = plain login digest-md5 cram-md5
auth_username_format = %Lu
first_valid_uid = 89
first_valid_gid = 89
log_path = /var/log/dovecot.log
login_greeting = Dovecot toaster ready.
mail_plugins = $mail_plugins quota
plugin/quota = maildir
protocols = imap pop3
ssl_cert = </var/qmail/control/servercert.pem
ssl_key = </var/qmail/control/servercert.pem
ssl_dh_parameters_length = 2048
namespace {
inbox = yes
location =
prefix =
separator = .
type = private
}
passdb {
args = cache_key=%u webmail=127.0.0.1
driver = vpopmail
}
protocol imap {
imap_client_workarounds = "delay-newmail"
mail_plugins = $mail_plugins imap_quota
}
protocol pop3 {
pop3_client_workarounds = outlook-no-nuls oe-ns-eoh
pop3_fast_size_lookups = yes
pop3_lock_session = yes
}
userdb {
args = cache_key=%u quota_template=quota_rule=*:backend=%q
driver = vpopmail
}
plugin {
quota = maildir:ignore=Trash
quota_rule = ?:storage=0
}
c) within conf.d/10-ssl.conf file appears uncommented:
ssl = required
I have changed it to "yes" and "no", restarted dovecot: same error
from this thread's Subject.
d) again in /etc/dovecot/conf.d/10-auth.conf
the line invoking vpopmail stuff is also commented
#!include auth-vpopmail.conf.ext
Any thoughts to begin with?

Subject: switched to new toaster: dovecot -ERR [AUTH] Plaintext authentication
disallowed on non-secure (SSL/TLS)...
Hello list,
I've installed a new fresh toaster on centos.6.x
Testing POP3 from localhost with dovecot is fine,
but from non-localhost, auth fails with
#telnet <public_ip> 110
Trying <public_ip>...
Connected to public_ip.
Escape character is '^]'.
+OK Dovecot toaster ready.
user [email protected]
-ERR [AUTH] Plaintext authentication disallowed on non-secure (SSL/TLS)
connections.
quit
"dovecot.conf" file is the usual:
!include toaster.conf
!include_try local.conf
and toaster.conf file has no extra editings:
# Settings for 'stock' qmail-toaster
auth_cache_size = 32M
auth_mechanisms = plain login digest-md5 cram-md5 <===
auth_username_format = %Lu
first_valid_uid = 89
first_valid_gid = 89
log_path = /var/log/dovecot.log
login_greeting = Dovecot toaster ready.
mail_plugins = $mail_plugins quota
plugin/quota = maildir
protocols = imap pop3
ssl_cert = </var/qmail/control/servercert.pem
ssl_key = </var/qmail/control/servercert.pem
# the following will likely be the default at some point
ssl_dh_parameters_length = 2048
....
dovecot.log shows lines like this one:
Aug 07 18:46:20 pop3-login: Info: Disconnected (tried to use disallowed
plaintext auth): .....
Is it an issue related with MySql ? Another thing to look?
Thanks in advance for your input!
regards
