Postfix additional transports - is it working?
- by threecheeseopera
I have enabled two additional transports in my postfix config to deal with recipient domains that demand connection limiting, per the instructions here at serverfault.
However, I have no idea if this is working or not; in fact, I think it is not working, due to the send speeds I am seeing in the logs.
How might I determine if my additional transports are working?
If they aren't, do you have any tips on figuring out why?
And, do you have any comments on my particular configuration? (am I a bucket of fail?)
I have enabled the additional transports in master.cf:
smtp inet n - - - - smtpd
careful unix - - n - 10 smtp
-o smtp_connect_timeout=5
-o smtp_helo_timeout=5
cautious unix - - n - - smtp
-o smtp_connect_timeout=5
-o smtp_helo_timeout=5
I have set up the transport mapping file /etc/postfix/transport:
hotmail.com cautious:
yahoo.com careful:
gmail.com cautious:
earthlink.net cautious:
msn.com cautious:
live.com cautious:
aol.com careful:
I have set up the transport mapping and some connection-limiting settings in main.cf:
transport_maps = hash:/etc/postfix/transport
careful_initial_destination_concurrency = 5
careful_destination_concurrency_limit = 10
cautious_destination_concurrency_limit = 50
Finally, I have run converted the transport file to a db per the postfix docs:
#> postmap /etc/postfix/transport
And then restarted postfix.
I do see my transport_maps setting when I run postconf, but I do not see any of the transport-specific settings ('careful_xxx_yyy_zzz'). Also the mail logs do not appear to be different in any way to what they were previously.
Thanks!!!
