Sendmail check_*
Posted On 2012年10月5日 星期五 at 於 上午9:27 by Lani最近遇到一些Sendmail的問題,
認真的研究一下後,發現其實Sendmail也蠻多檢查機制。
Introduction
If you plan to upgrade your sendmail version, go directly to the current release of sendmail (or at least 8.9.3) which has standard FEATURE
s included. However, you may read on, because this page and related pages give background informations about the check_* rulesets.
sendmail 8.8 introduced several new rulesets to control who can use your machine to send/relay e-mail and to avoid UBE from well known sites. These are:
- check_relay
- checking the host name and host address separated by $|. This ruleset is called whenever a client connects via (E)SMTP to the server.
- check_mail
- for the MAIL command.
- check_rcpt
- for the RCPT command (used to prevent unauthorized relaying). This ruleset disables all kinds of known relaying tricks (the trick which is tested by ORBS currently (1999-07-14) is fixed since the end of 1997 according to my logs).
- check_compat
- checking both MAIL and RCPT also separated by $| before delivery.
