I guess you didn't see my reply to you earlier in this thread:
You get that information from your email provider. Please reach out to your email provider to see what information you need to use here.
There is no way for us to tell you what information to use as we do not know what email provider you are using; we are not psychics. You will need to reach out to your mail provider to see what Hostnames and Port Numbers you should use for IMAP/POP3 and SMTP.
Cheers.
