Hello,

The standard POP3 server runs in port 110 and is generally up to the user to decide which service they want to use. You can use something like qpopper for your POP3 daemon or you can use something like cyrus imap or dovecot that handles both POP3 and IMAP.

Please let us know if there is anything else we can help you with.

Best,

Hi Mike,

Thank you for your answer. Could you please elaborate
where and how to define the service I want?
