[Mailman-Users] Mailman with Postfix installation error

[Alonso Landauro Canales]

Hello:

I am new at the list. I am also new at mailman. But I ve  been reading
and installing well mailman until now.
I am having some problems.
I think the problem is that mailman couldnt catch with postfix. Dont
know why.
Its says host not found.. But I dont know where to fix this.

The error log is:
