POP3 server does not process the optional message num argument of the LIST command

[jenshb]

According to RFC-1939, the list command can have an optional msg_num argument. See https://datatracker.ietf.org/doc/html/rfc1939#page-6.
This leads to an error, when the POP3 client relies on this command.

Thanks @jenshb. Can you please confirm that your PR works correctly with your POP3 client which relies on this command?

Hi @axllent ,
I'm using Mailpit with the camunda distribution. The Camunda Email Connector worked fine with the Mailpit smtp-Server, but I got errors when trying to list emails with the pop3 protocol when there was more then one message on the server. With the PR, it works.
Thanks for the great project!
Jens
