postfix configuration

[Pau Novella <pau.novella.garijo@cern.ch>]

Hi,

I have just installed successfully posfix as my mail server. Now I can send 
e-mails with both commands "mail" and "sendmail" but my problem is that the 
mail arriving has a "wrong name of sender" and a wrong "from" adress. It's 
just like this:

from: name1 <name2@domain>

These names and adress are not the ones I have set in the main.cf file (and I 
don't know where they come from!!!).
I can't find the correct place or the correct words to fix this parameters: I 
googled and looked at my configuration files with no result.

Now I had found out that I can modify the name and adress using differents 
options in the MUA, but I would like to have the corrects ones fixed in the 
postfix configuration.


Can anybody help me?  

Thanks!!
