Connected to da.mx.aol.com.
Escape character is '^]'.
220-rly-da05.mx.aol.com ESMTP mail_relay_in-da05.2; Thu, 17 Jan 2008 13:03:52 -0500
220-America Online (AOL) and its affiliated companies do not
220- authorize the use of its proprietary computers and computer
220- networks to accept, transmit, or distribute unsolicited bulk
