smtplib does not send to all recipients

[dccarson at gmail.com]

I changed debuglevel to 1 and looked at the response on the recipient
names.  They are BOTH accepted, but still only my id (d123456) receives
the e-mail.  The long id (d1234567890) never gets the e-mail.  Here is
the excerpt of the exchange.

send: 'mail FROM:<d123456 at myDomainHere.com> size=160\r\n'
reply: '250 2.1.0 <d123456 at myDomainHere.com>... Sender ok\r\n'
reply: retcode (250); Msg: 2.1.0 <d132456 at myDomainHere.com>... Sender
ok
send: 'rcpt TO:<d123456>\r\n'
reply: '250 2.1.5 <d123456>... Recipient ok\r\n'
reply: retcode (250); Msg: 2.1.5 <d123456>... Recipient ok
send: 'rcpt TO:<d1234567890>\r\n'
