The POP3/IMAP server says "Temporary problem, please try again later" when a bad password is entered. authdaemond tries each of the configured authentication modules in turn, until either one accepts the login, or they have all rejected it (in which case the usual "Login failed" error is returned, and the user can try again). However, if one of these modules is unable to run because some resource is not available, then it gives a temporary failure response and no further modules are tried. The error is more clear in Plesk 12.5.

Turn up the debugging options in the authentication daemon config file, restart the daemon, and use the "authtest" program to check before you try and login to Courier IMAP. That will log any MySQL-related errors. ------------------------------------------------------------------------- Take Surveys. Earn Cash.

My problem start today suddenly. I have a Cpanel server in softlayer that have some websites. Today a lot of clients start calling here complaning about email issue. Clients repporting that Outlook ever ask about password even with the correct password. So I had a look on /var/log/maillog and I saw hundreds of error messages like the following: === Feb 28 17:09:26 server01 pop3d: LOGIN FAILED, [emailprotected], ip=[::ffff:xxx.41.202.57] Feb 28 17:09:26 server01 pop3d: authentication error: Input/output error === To be more exact, I saw 5,000 messages like this up: === [emailprotected] [/etc/apf]# cat /var/log/maillog | grep 'Feb 28' | grep 'LOGIN FAILED' | wc -l 5021 [emailprotected] [/etc/apf]# === So I restart imap and POP3 service in WHM. When I restart, LOGIN FAILED stoped. But after some minutes the problem come back. I reatarted services again, worked for some minuts and issue come back. So I try some comands: /scripts/upcp /scripts/courierup /scripts/imapup /scripts/eximup Nothing help. Issue still persist. I dont know what I must to do to fix it. I tried Softlayer support without any sucesss. Only quicky rep

Need some help please ;) I'm setting up a mail server on an Ubuntu 14 AWS EC2 instance using mysql backend, postfix MTA and roundcube webmail client. Everything is working up to the point of logging in via roundcube. ie, I can send and receive mail from the shell when i telnet into localhost on port 25 and mail boxes are created in /var/mail/virtual/. All looks good. When I try to login with a user that exists in the "users" table the roundcube client returns the following error: Connection to storage server failed. So. Here is the /var/log/roundcube/error message: [04-Jan-2016 17:43:42 +0000]: IMAP Error: Login failed for email@mydomain.co.uk from [IPADDR] LOGIN: Temporary problem, please try again later in /usr/share/roundcube/program/lib/Roundcube/rcube_imap.php on line 184 (POST /roundcube/?_task=login&_action=login) and the error logged in /var/log/mail : Jan 4 17:49:56 ip-172-31-46-150 imapd: Connection, ip [::ffff:127.0.0.1] Jan 4 17:49:56 ip-172-31-46-150 authdaemond: received auth request, service=imap, authtype=login Jan 4 17:49:56 ip-172-31-46-150 authdaemond: authmysql: trying this module Jan 4 17:49:56 ip-172-31-46-150 authdaemond: authmysqllib: connected.
