I have Debian 7.3 VPS with Webmin, Apache, MySQL, PHP and Postfix and DOvecot for handing emails.
Throughout Webmins "read user mail" option, I can send/receive emails, but it looks ugly and it is not practical and not very usefull.
So I installed Roundcube and tried to login and got this message: "Login failed."
So I go to terminal and entered:
# terminal localhost pop3
Connected to localhost.
Escape character is '^]'.
+OK Dovecot ready.
user myusername
+OK
pass mypassword
-ERR [IN-USE] Internal error occurred. Refer to server log for more information.
Connection closed by foreign host.
And there I stuck.
Log doesn't tell me something usefull.
# grep -i dovecot /var/log/syslog
Jan 23 00:22:52 MyHOstName dovecot: imap-login: Aborted login (auth failed, 1 attempts in 4 secs): user=<[email protected]>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, secured, session=<XXXXXXXXXXXXXXX>
Jan 23 00:23:05 MyHOstName dovecot: pop3-login: Aborted login (tried to use disallowed plaintext auth): user=<>, rip=XXX.X.XX.XXX, lip=XXX.XXX.XXX.XX, session=<XXXXXXXXXXXXXXX>
What I should do?
Thanks in advance!
