[Sqlgrey-users] Comments and features requests

[Michel B. <mi...@bo...>]

Hi there,

I've started using SQLgrey a couple of days ago, and I'm rather happy with it.

I have however a couple of comments and feature requests :

1/ In the provided "clients_fqdn_whitelist", the following line:
scd.yahoo.com
is wrong, does not work, and should be replaced with
*.scd.yahoo.com

2/ The latest version of Postgrey allows specifying the result (both code and 
text) that Postgrey should give when a connection is greylisted. It would be 
nice if SQLgrey could do the same.
Currently SQLgrey returns "defer_if_permit" and this cannot be modified 
(except by fiddling in the code).
However, some may prefer to reject immediately with a 450 temporary failure, 
rather than carry on with further potentially expensive Postfix tests (such 
as checking external DNSBLs or verifying sender existence), where the 
connection will in the end be rejected anyway...

3/ It would be nice to have a whitelist of senders (using regexps) for whom 
greylisting should never be done. This list should by default include the 
addresses that some MTA use to perform "sender address verification", as we 
should avoid greylisting those verifications as much as possible, the 
combination of greylisting and sender address verification introducing 
problems and rather long delays. These verification origin addresses are, 
among the most common:
<> (null sender)
MAILER-DAEMON@*
postmaster@*


Thanks for this excellent piece of software.

Regards.
