ratelimiting locally originating messages
in [Postfix]
|
From: Vladimir Vassiliev on 9 Apr 2010 07:03 Hi postfixers, thanks to http://www.postfix.org/QSHAPE_README.html I learned how to limit rate of sending messages which arrives via smtpd. Now I tries to do the same with locally originating (via sendmail) messages. It seems usual recipes doesn't work. What are the best practices to do this? Several postfix instances or something else? -- Vladimir Vassiliev

It seems usual recipes doesn't work. The techniques in QSHAPE_README work while Postfix DELIVERs mail, regardless of how Postfix RECEIVES mail. Wietse > What are the best practices to do this?

From: Vladimir Vassiliev on 9 Apr 2010 08:00 I need sender based selection so I used policy server to choose right transport: smtpd_recipient_restrictions = check_policy_service unix:private/policy permit_mynetworks, reject_unauth_destination And smtpd_*_restrictions don't work with sendmail originating messages. 09.04.2010 15:47, Wietse Venema пишет: > Vladimir Vassiliev: >> >> Hi postfixers, >> >> thanks to http://www.postfix.org/QSHAPE_README.html I learned how to >> limit rate of sending messages which arrives via smtpd. >> Now I tries to do the same with locally originating (via sendmail) >> messages.

QSHAPE_REAME does not cover sender-dependent selection; and I already mentioned that its solutions to limit the sending rate limit are independent of how mail was received. That said, Postfix 2.7 has sender_dependent_default_transport_maps to override the default_transport setting, again, in a manner that does not depend on how mail was received. Wietse

Ok, I was not clear with my first message Here is my config: main.cf: smtpd_recipient_restrictions = check_policy_service unix:private/policy permit_mynetworks, reject_unauth_destination master.cf: slow_smtp unix - - n - 3 smtp -o fallback_relay=[real_relay] -o smtp_connect_timeout=1 -o smtp_connection_cache_on_demand=no Policy server returns "filter slow_smtp:[dead.host]" for specific messages (currently selection base on sender and recipient but later I'll try also size). This recipe works perfectly for messages arriving via smtp, and question is how it's possible to do the same for sendmail-arriving ones? 09.04.2010 16:41, Wietse Venema пишет: > Vladimir Vassiliev: >> >> I need sender based selection > > You wrote that you learned from QSHAPE_REAME how to limit the rate > of sending messages which arrives via smtpd. > > QSHAPE_REAME does not cover sender-dependent selection; and I > already mentioned that its solutions to limit the sending rate > limit are independent of how mail was received. > > That said, Postfix 2.7 has sender_dependent_default_transport_maps > to override the default_transport setting, again, in a manner that > does not depend on how mail was received. > > Wietse -- Vladimir Vassiliev |
