Hi Stephen,

Ah, more info!  The trailing "=" hadn't been mentionned previously...

I've created a sample mesage containing "alpha" ( "a=<CR><LF>lpha" )
and "beta" ( "b=<LF>eta" ) split as you've described:

### begin message ###
Subject: test

CRLF:
a=
lpha

LF:
b=
eta
### end message ###

Since claws-mail doesn't show <CR> or <LF>, I've attached a tgz file
with the message.  The tgz also includes a hex dump of the message so
you can see the CR and LF characters.

Bogofilter's -vvv results (with and without "--min-token-len=1") is at
the end of the message.  In neither case do I see bogofilter combining
characters before/after a final "=" sign.  Perhaps you can gzip a
sample message and send it?

Regards,

David
