I suppose it's compatible with transport map in transport.db Maybe I can put in master.cf yahoo unix - - n - 1 smtp -o smtp_connection_cache_reuse_limit=15s -o smtp_connection_reuse_time_limit=20s smtp_connection_cache_time_limit=1s Mick -----Message d'origine----- De : owner-postfix-us...@postfix.org [mailto:owner-postfix-us...@postfix.org] De la part de Noel Jones Envoyé : jeudi 15 septembre 2011 18:17 À : postfix-users@postfix.org Objet : Re: Rate delay, concurrency and recipient per domain On 9/15/2011 7:56 AM, Mickael B wrote: > Dear, > > > > I will be more accurate. > > > > My postfix configuration is like this : > > I use yahoo domain for exemple : > > > > Transport : > > > > yahoo.com yahoo: > > yahoo.fr yahoo: > > > > Master.cf > > yahoo unix - - n - 1 smtp > > > > Main.cf > > yahoo_destination_concurrency_limit = 20 > yahoo_destination_rate_delay = 10s yahoo_destination_recipient_limit > = 20 > > > > When I setup the rate delay this force a concurrency of 1. Yes. As documented, rate delay forces a concurrency of 1. You've also specified a process limit of 1 in your master.cf yahoo transport; that will also limit concurrency to 1. If you want to use a custom transport for yahoo (useful to set a shorter connect timeout), you should set a process limit of 20. > I also try to setup the cache connection to keep the connection open > and send more email per open connection. > > yahoo_connection_cache_reuse_limit = 15s > yahoo_connection_reuse_time_limit = 20s > yahoo_connection_cache_time_limit = 1s I don't see in the documentation where you can use [mumble]_connection_* parameters, so I don't expect this to work. > With this configuration my send are send 1 by 1 to yahoo domain. > > I would like send the email to yahoo domain according with > recommendation of yahoo postmaster advice: > > 20 simultanous connection and 20 messages send per open SMTP > connection and finaly no more than 600 connection to yahoo MX per hour. The postfix default settings should work reasonably well for this with no tuning, although you may want to add yahoo.com to smtpd_connection_cache_destinations to force caching for them. If you're sending a high volume of mail to yahoo (many thousands per day), you'll need to sign up as a bulk mailer. -- Noel Jones
