I have completed the whole guide at purplehart.org up to postfixadmin. in the last step that says the following:
#telnet localhost 110
Connected to host.domain.tld.
Escape character is ‘^]’.
+OK ISP Mail Server Ready.
user
user@domain.tld (Use the account you created via the web interface)
+OK
pass password (Use password you just created for above user)
When I enter the password I entered in postfixadmin I get the following error:
-ERR Temporary authentication failure.
Connection closed by foreign host.
Any tip on where to look?
