finally, i think i've found out what is going wrong. sendmail doesn't 
work (even for the local delivery), because it tries to contact
	localhost.xxxxx.xxxxx.xx
instead of
	snail.xxxxx.xxxxx.xx
where snail is the name of my computer. however, hostname gives "snail", 
/etc/rc.conf contains hostname=snail.xxxxx.xxxxx.xx, i even created 
/etc/myname with "snail" in it... but it still doesn't work. can anyone 
tell me what's wrong here? is there some other config file i missed?

regards,
