sending mail from the command line

[Jonathan Ben Avraham]

Hi Dan,
Indeed it looks as though your mail did in fact go out to gmail. There is 
a chance that gmail silently dropped your mail in its spam filter.

You could use tcpdump (as in wireshark) on outgoing traffic to destination 
port 25 to examine the traffic between your machine and the receiving 
machine. Alternately you could send to another mail server that has less 
opaque filtering.

Regards,
