Why do you believe you need PCRE to implement a policy that only accepts mail for certain recipients? -- Viktor. Disclaimer: off-list followups get on-list replies or get ignored.

	RE: need help with pcre for postfix by Sharma, Ashish-2 :: Rate this Message: Reply to Author \| View Threaded \| Show Only this Message Pascal, You can create a mail filter for Postfix using Milter API. For c implementation you can use lib-milter API and for Java implementation you can use 'Jilter' API. It's possible to write code depending on your requirement as mentioned by you: > can someone help me write a filter who would accept mail for >"postmaster@domain" and reject all other mails ? I have a sample Jilter implementation in java for understanding Jilter implementation, reply if you need it.

	Re: need help with pcre for postfix by VALOIS, Pascal :: Rate this Message: Reply to Author \| View Threaded \| Show Only this Message hum, i think i found what was wrong. when checking with pcre, all lines in the header are processed. and then the "from: adress" get a REJECT go away reponse from the filter. i though that all the subject was processed as once ? right or wrong ?

(Hint: DO NOT). http://www.postfix.org/postconf.5.html#smtpd_recipient_restrictions http://www.postfix.org/postconf.5.html#check_recipient_access http://www.postfix.org/access.5.html Find a decent tutorial on Postfix restriction processing. > then here is the content of my /etc/postfix/header_checks : > > !/postmaster@devinci\.fr/ REJECT go away > > but when this is enables, all mail are rejected. > > can anyone help me with this ? Don't reject all messages that contain header lines that don't mention the postmaster address. -- Viktor. Disclaimer: off-list followups get on-list replies or get ignored.
