"LOGIN" is not a valid POP3 command -- it is an authentication method.

Depending on what auth methods you have enabled the password you have to
send during a login sequence may have to be CRYPTed before typing it in.

Here is the sequence for logging in via telnet to check what the server
thinks is in your mail directory.

(Yes, it says AVG POP3 Proxy server -- that's the virus gateway installed
on the windows machine I am doing this from -- it opens a clean pipe to the
Dovecot server at the other end of the "telnet myserver.domain.tld 110"
command.

telnet myserver.domain.tld 110
+OK AVG POP3 Proxy Server 7.0.307/7.0.308 [266.9.1]
user myuser at mydomain.tld
+OK
pass mypass
+OK Logged in.
