same as i saw...

umm... are you talking about BF's above or ??? the above was written on his
230/2 system... he seems to be saying that squishmail on his 230/0 is the
system stripping the leading blank lines from the message bodies in all traffic
it handles...

 WV> we are discussing here. ;)

i'm not sure about that ;)  i can easily see there being possibly two options
for stripping leading blank lines...

  1. when tossing messages into the local message bases
  2. when scanning out messages posted locally

but any kind of *in-transit* changes to _echomail_ are frowned on... other than
adding/sorting the seenbys and adding to the path and changing the few
necessary header fields, of course...

 BF>> And if so, what "spec" does it violate?

But

not to mention throwing off duplicate detection... there's a lot of systems
that use multiple methods of dupe detection... one of those methods is to run a
few checksums on selected fields and the message body... they do this in
addition to using the MSGID and other methods they may employ... systems that
sorted the control lines into some order they use for locally generated posts
were caught in ""recent"" years and ""corrected"" or are no longer on the
network any more...

i know of a number of systems that will dupe-out a message if the message body
is exactly the same even though the MSGID and header fields are different...
they do not count control lines, seenbys, or path lines as being part of the
message body... i don't recall if they stop at the tear and/or origin lines or
if they are even included in the checksum formula... they could be since tear
and origin lines should not be modified at all... negating them is different
and changes the message body anyway since the negated ones become message body
at that time... negating them would be done when gating from one FTN to
another, of course ;)

you're right about that! -=B-)
