From Ted===
Dear Webby,
I have had a few mailer daemon returns like this one I just
received.

Sorry. Your message could not be delivered to:
joshua croft,DCSD Mail (The name was not found at the
remote site. Check that the name has been entered correctly.)

The problem is I never sent a message to the delivery
addresses on these Daemon returns. Could spyware be using
my computer to send messages that I am unaware of. If so
what can I do about it?
Ted

Dear Ted
There is a lot of spam coming out of comcast, so much in
fact that the blacklists flag it as bad. Part of that is
probably due to @comcast.net addresses being available
to spammers, who forge them as return addresses.

When spam, that has your address forged as the return
address, bounces back from a full or no longer working
address, it of course bounces to you.

Just make a filter with MailWasher to trash mail that has
your return or sender address but not your machine ID.

Have FUN!
DearWebby
