Courier POP3 login refusal
I just installed Postfix and Courier. Postfix can receive messages (I can monitor from Webmin GUI) but when I try login inside or outside the network, it asks username and password then -ERR login failed. I try logging in with real accounts. What can be wrong. SMTP working okay but POP3 wont let me in..
I tried "telnet localhost pop3" or "telnet xx.xxx.xxx.xx 110" and both giving the same error.
Thanks for helping
