  A BASE64 decode would tell who is sending that thing, but contacting
  backwards shows it to be:

Connected to 202.54.32.129.
220 swathi.ecil.co.in ESMTP server (Netscape Messaging Server - Version 3.01) ready Thu, 13 Jan 2000 11:36:39 +0530
ehlo foo
250-swathi.ecil.co.in
250-HELP
250-EXPN
250-ETRN
250-PIPELINING
250-DSN
250 AUTH=LOGIN
quit
221 swathi.ecil.co.in ESMTP server closing connection

  Sigh, VGER is running 2.99.51-pre2 (I haven't gotten around to install
  2.99.52-patch1 there yet)  And VGER doesn't announce AUTH LOGIN
  nor AUTH=LOGIN capability.  That system is thus sending unsolicited
  "AUTH LOGIN" :-(

  Now I wonder whom to contact about that bug ??
  Its Postmaster very least.
