Is the wife using a macbook? 

I have seen something like this a
couple of times before with users with Mac hardware.

it may be running but does not appear to be parsing the maillog

from) show up in the poprelayd -p output. As for why only affecting a
few, try doing an RBL check against their IP addresses, it may be those
are listed somewhere and causing sendmail to block the send.

some ISPs including comcast do block port 25, so use 587 I believe
