No, although all these things are true in general, they are not the problem 
referred to by Andrew.

Gmail deliberately does not send you copies of your own emails.  This is 
policy, not a bug, according to Gmail.  It also suppresses all 
other "duplicates".  (What you send is a duplicate because it will be in your 
sent folder.)

The _solution_, not the problem, is to use a different smtp server, not 
Gmail's smtp server.  This results in the DKIM signature not matching as E 
Liddell says, but Gmail then sends you your postings and I get copies of 
everything I send to the list.  The non-matching DKIM signature *very* 
occasionally causes me problems elsewhere.
