This is irrelevant, really.

Please look to this queue file:
 postcat /var/spool/postfix/deferred/*/DEB8ED90B3 | more
-- it should contain a line with a single dot (.)

No, only partial copies, all lines before that "one-dot-line".

This is a historical bug I discovered yesterday, but forgot to add it to
ChangeLog.  av(p)check should use `-i' argument when calling real
sendmail.  Only avcheck-0.2 contains this fix.  I'm afraid you need
to drop avpcheck for now and use avcheck, or just switch to use smtp
(-Shost:port) -- last one is faster anyway.

AvpDaemon is not an issue here, it's not it's bug.

That bug exists because some time ago postfix's sendmail command
didn't have -i option at all (even FILTER_README was corrected
very recently), and I used my tiny smtp client "msendmail" that
hasn't it either.

If you don't know, -i stands for "do not treat line that contains
a single dot as end of a message" -- i.e. do not use "hidden dot
algorithm" on *input* (ugly like a hell but sendmail does this!).

BTW, we need to correct all the docs etc to be current.
Ralf, can I "stole" your HOWTO and include it into package with
proper corrections?

 Michael.
