You have a DNS issue someplace.

--- verify e-mail "user1@xxxxxxxxxxxxxxxxxxxxx"
--- looking up mailexchange for sherlock.stanford.edu
--- unable to find mailexchange, contacting sherlock.stanford.edu
--- error: Host not found

But, checking your "wrong" address:

> RCPT TO: <user1@xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx>
250 <user1@xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx>... Recipient ok

sherlock.stanford.edu.millenium-online.com	A	216.234.186.162


--- DNS lookup for "sherlock.stanford.edu", please wait...

    DNS Server Response 3: Name Error.
