My tmda is broken.  When a not whitelisted person sends me mail, he gets

Mate, it looks like the "Reply-to" header is missing from the TMDA 
challenge emails. Why this would occur, I have no idea.

To verify this, send mail explicitly to the address in the body of the 
confirmation request email. You should see the message released to the 
intended destination.
   

It indeed is the case.
 

Do you control the whole email system? If not, I'm betting that your 
sysadmin is re-writing the From and removing Reply-To in an attempt to 
reduce email forgery or something...

   

I am controlling the whole email system, and in my original message, I
gave my .qmail files:
$ cat .qmail
|preline /usr/bin/tmda-filter
./Maildir/
$ cat .qmail-tmda-default 
|preline /usr/bin/tmda-filter

How can I test what exact confirmation message tmda gives to qmail?

This may be related to the problems you mentioned in your tmda-workers 
post. Maybe qmail's sendmail emulation trashes From/Reply-To when the 
QMAILUSER/HOST variables are set. Try using SMTP for email transport and 
see if that fixes it. also, does your system use an SMTP smarthost 
(which could theoretically be munging things?) or deliver direct to the 
recipient?

I'm not sure how you'd capture TMDA's outgoing email. Perhaps replacing 
qmail's sendmail with a wrapper that captures the data, then passes it 
on to the real script...
