A scripting question

[Walter Dnes]

  AWK, bash, sed, vim macro, perl, tr, whatever.  I have a remote inbox
with clss.net, which allows me to control smtp-stage blocking by DNSbl,
IP address, rDNS, etc.  I also get a log file.  I want to be able to re-
format the logfile for my own statistics.  Each reject causes 3 lines to
be written to the logfile;
  1) Originator + destination
  2) A TXT output, plus a message of my choosing.
  3) A zero-length line

  Here's an example.  Note that it does *NOT* really have the leading
"> "; that's just there to prevent linewrap in this message.

  I can get rid of the blank lines with
grep -v "^..."

  And I can get rid of the pointer to my unfiltered email address with
sed "s/If yours was.*$//"

  This leaves me with...

  I want to roll up the two lines for each reject into one long line
like so.  Again, the leading "> " isn't really there.

  How do I remove every second end-of-line to achieve this ?
