Stop SPAM, please

[rms]

Hello,

  I don't know who manages your mailer daemon, but you must kill it's open relay 
status. I'm receiving a lot of spam which is being delivered through 
parsons.abisource.com.

  Sooner or later, this relay might be found in the open relay blacklist, and some 
ISP's may choose to block mail coming from parsons.

Regards, rms
