identity?

[Lewi]

where I can find setting for default identity,
my installation doesn't display from in FQDN
just for ex
abc.mydomain.com
if I sent from imp, then from address look like this
user at mydomain.com


where I can change this, because this cause problem with mailman
with restrict members posting
