Can you confirm that it didn't get to the list?  (Check archives)

Stupid question, but is he subscribed?  Most vox-* lists just discard
junk from non-subscribers -- it doesn't even hold them.  (I only do
that for vox-jobs@ (and maybe one other) since it's more likely
to get drive-by posts, and isn't much of a "discussion" list.)

If I _happen_ to look and notice an actual legin email from a
non-subscriber, I fwd it to the list on their behalf (and I typically
point out "they sent it from a non-subscribed address" at the top).
USUALLY it's someone trying to post to the list, who is subscribed
under a different email address than the one they actually tried to
post from.

Thanks,

Common, many lists and mail servers suppress email from yourself.  To 
not do so risks infinite loops from broken vacation messages and the like.



He has a gmail account.
I have a mail server I manage that is connected to Comcast business
and I had to implement dkim on outbound messages so that they would
make it to gmail. I wonder if we need to put dkim on the vox mailing
list?


In my experience adding DKIM or not, doesn't change much.  Gmail does 
add a nice little green ball with a "signed by: ", but it 
doesn't effect spam scores and the like much or at all.


With all that said I think DKIM is useful, but mailing lists have to 
decide to do one of:

A) not touch any headers DKIM decides to sign, like for instance the
   subject line and signature.
B) resign all message from dkim.

I like the later option since (IMO) the mailing list should verify 
incoming email, apply anti-virus, and anti-spam.  Then if it passes all 
that it should resign.  That way all subscribers can be sure it's 
actually email from the list not a forgery that looks like it's from the 
list.


Sadly email is pretty much a lost cause for security, privacy, and 
authenticity.  If you do a really good job of it, it's not really email 
anymore.

Yes, gmail hides duplicates. If you sent the email there is no way in
gmail to verify that the list received it within gmail. You'd have to
look at the online archives or cc some other email of yours.

I had the experience where gmail filters out email from myself. Not sure if
that's what's happening.
