Hi My postfix is running and webmail (uebimiau) send and receive emails of user@domain, but email clients (oultlook, thunderbird, etc) not login in server. The error message is: Bad Login. Email client is configured in POP3 with login user@domain in server IP or DNS name. DNS is ok (ispconfig panel is working). User is ok (webmail is working)... Please, help me...
What error message is returned by your email clients? What to the postfix mail and error mail log say?
You're using the wrong username. In Uebimiau webmail you use the email address, but in email clients such as Outlook or Thunderbird you must use the username of the user, e.g. web1_someuser.
