[ilug] Postfix error -> this is easy...not for me though

[Wynne, Conor]

Hi all,

I downloaded all my mail last night after the holliers, took ages & ages.
Then I went to me inbox, and it said, you have no new mail or something.
Here in work where I sent some of them from, I received these errors

This is the Postfix program at host daddybear.daisynet.ie.

<wynnec at daisynet.ie>: unknown user: "wynnec"

Now I obviously changed something but I dont know what [probably something
to do with aliases] -still a mail newbie- 
I'll explain, the error is correct as there is no user called wynnec. I used
to have wynnec mapped to cwynne. Why? Because my login to me pop mail is
wynnec, and fetchmail collects it and supposed to send it on to the local
user cwynne. So how do I fix that? 

I know your all laughing at me but I don't care, I have this mental block
with mail servers. I even bought the sendmail batbook of Nialler, not that
it did me any good :)

I'm off to read the register
