Hey guys, I have set up an OpenSMTPD server to use as mailing server for corporate spam and phishing simulations. The server will typically get a bunch of emails (50-1000) to be sent to the same domain.
Are there any configuration options that will help optimize this use-case? Currently I'm experiencing two issues: The target mailserver drops mails because too many are sent (around 100). (I guess a whitelist on target server is best solution, but limiting outgoing speed could be easier?). OpenSMTPD is blocking my client that is sending mails with: 452 4.5.3 Too many recipients: Too many messages sent Especially the last one is an issue for me. Current config: listen on lo tag TO_DKIM hostname $domain mask-source listen on lo tag FROM_DKIM port 10029 hostname $domain accept tagged TO_DKIM sender "@$domain" for any relay via smtp://127.0.0.1:10028 hostname $domain accept tagged FROM_DKIM for any relay hostname $domain Thanks! :) Joris -- You received this mail because you are subscribed to email@example.com To unsubscribe, send a mail to: misc+unsubscr...@opensmtpd.org
