[Sqlgrey-users] prevent multiple headers prepended for each RCPT

[Sascha L. <sas...@ru...>]

Hi list,

I have configured sqlgrey-1.6.5 to PREPEND the X-Greylist: header. What I 
noticed is that the header was prepended multiple times (for each RCPT TO) 
in the mail. The logfile shows also "sqlgrey: grey: from awl match: 
updating" for each RCPT TO.

My question is: can the instance= in the postfix policy protocol be 
used, to prevent multiple action=PREPEND .... ? From postfix's 
SMTPD_POLICY_READM the instance=... can be used to correlate different 
requests regarding the same message delivery.

THX,

Sascha.
