webmail login is invalid and outlook keep asking for password

psytanium
Hello, I was running my users on a shared server, emails communication was fine. Now I have migrated to a VPS server. that's were I started to deal with some problems as I'm completely new here. What is happening: My clients use pop3 connection. Outlook is functional, they can send and receive emails, but it keep asking for the password. If they try to login from the Webmail, they get the "The login is invalid" as if the password is incorrect. But I can login to their accounts using the webmail on my work computer. This is happening with all my 9 users. I appreciate any hints.

    Hello Please deactivate your cPhulk in cPanel/WHM and try again with your email account. You can kill processes in your server or fully disabled cphulk protection for i in `ps aux | grep -i "cphulkd - process" | awk {'print $2'}` ;do kill -9 $i ;done /usr/local/cpanel/bin/cphulk_pam_ctl --disable
    Thank you.

    can't get to run OpenSSH on Windows yet. anyway I have turned off cphulk and flashed DB from the server GUI. now some clients can login from the Webmail, others still can't. but all of them they still have the outlook asking for password repeatedly.

    Hello, Can you use telnet to test login? #telnet localhost 110 Trying 127.0.0.1... Connected to localhost. Escape character is '^]'. +OK Dovecot ready. user emailaddresshere pass passwordhere
    What do you see? Also check /var/log/maillog for errors at the same time.

    Putty is just a SSH client, so you can run commands as you normally would. There are no special requirements. Thank you.

    Thank you so much for your patience with me. I have used windows cmd and did the following: telnet server.xxxxx.com 110 USER PASS LIST I was connected, logged in, and i got a list of emails it think. Is that what you asked me to do ?

    Check the output from /var/log/maillog when your users report authentication failures and let us know what you see. You could actively review the output from this file as authentication failures occur with a command such as: tail -f /var/log/maillog
    Thank you.

    I am having a similar problem, only it is Apple Mail that is saying the password is invalid. Nothing has changed on the server side; one day it just stopped working. If I log in through the webmail version I can get in, however.

    I have added their IPs to the white list in cPhulk. Now all of them can login from Webmail and Outlook behave normally. But its not practical to do this procedure all the time, i think there is another solution.

    Please see the post prior to yours for information regarding /var/log/maillog. Thank you.
