Hi,
 
i followed the tutorial available on 
http://www.coolder.com/iblog/?p=32 in order to setup a testing mail 
server on my local PC (under windows 7).
i setup it at first using my gmail account and it was working perfectly as relay for my web development purpose.
later i setup our company smtp server address and once again it was working perfectly.
 
i
 went 2 weeks on holidays and today i needed to test a mail sending from
 my web development computer (the same as before and the same which 
holds Mercury/32 server) and now it doesn't work.
i didn't change anything... just switch off/on computer before and after my holidays... so what's happening ?
moreover
 mail server sends email/error notifications to postmaster@localhost 
however, i'm not able to get them whatever mail client i use (pegasus 
mail client or thunderbird)
 
1. how to get error notifications to postmaster ?
 
i know i'm a rookie regarding mail servers but with tutorials i can't make a mistake... especially when it worked before :-(
 
thank a lot for helping me.
