Setting up mail on Mac Lion

I set up a friend’s email account. For incoming mail only Imaps works, even though I actually want to set up Pop, for outgoing mail only mail.bluewin.ch works, even though I actually want to set up smtpauth. Settings, ports, passwords, etc. are correct. What could it be?
Thanks.

Thanks for the tip. I know the link and have tried the automatic version and the manual. Imaps works, and so does outgoing mail, albeit with a delay.
My account runs smoothly on my own Mac.
I saw in another thread that the delay is also an issue (dns).
Will keep trying.
