Hi all ,
i'm using 8 mta's on 8 different servers, and one server that hosts 8 different mailwizzes for each mta.
everything worked fine until i start realizing that the server is getting very slow.
i checked the mailq and saw that there are 267778 bounce requests, and when i checked the load i saw that dovecot is causing ridiculous high load - load average: 46.40, 28.08, 24.61 load average: 53.10, 51.63, 42.31, load average: 92.91, 33.31, 13.95
i had to stop dovecot in order to get a simple task right -
My question is - how can i handle bounce differenly?
what can i do to keep the important bounce service, but maintain a cool server without very high load?

thank you!

@vladimirKobi - Did you change the default settings for bounce handling from backend > settings > cron area ?
What you could do, is to try to process a smaller number of bounces at once, then run the cron job for bounce handling by hand and see how it behaves, then if the load is fine, do a small shell script that will trigger the bounce handler command in a loop, this way processing very small amounts of bounces but doing it continously.

@vladimirKobi - increase the number of servers at once to 10, 500 subscribers at once. then disable the cron job for bounce handling and run it manually several times.
