yes: data we receive in an smtp session comes from untrusted client. if you don't apply boundaries, someone like me is going to establish lot of concurrent connections that will send enless streams of bytes to fill your memory until it exhausts and your server is rendered unusable. limits guarantee that at one given time a client is not taking more than a pre-established amount of resources. -- Gilles Chehade https://www.poolp.org @poolpOrg -- You received this mail because you are subscribed to misc@opensmtpd.org To unsubscribe, send a mail to: misc+unsubscr...@opensmtpd.org
