It's not hit mainstream -use, but has apparently been implemented in the META1 MTA. - -There is mention at http://mail.aegee.org/intern/sendmail.html -of a patch to sendmail "to make it PRDR capable". - - ref: http://www.eric-a-hall.com/specs/draft-hall-prdr-00.txt - -If Exim is built with EXPERIMENTAL_PRDR there is a new config -boolean "prdr_enable" which controls whether PRDR is advertised -as part of an EHLO response, a new "acl_data_smtp_prdr" ACL -(called for each recipient, after data arrives but before the -data ACL), and a new smtp transport option "hosts_try_prdr". - -PRDR may be used to support per-user content filtering. Without it -one must defer any recipient after the first that has a different -content-filter configuration. With PRDR, the RCPT-time check -for this can be disabled when the MAIL-time $smtp_command included -"PRDR". Any required difference in behaviour of the main DATA-time -ACL should however depend on the PRDR-time ACL having run, as Exim -will avoid doing so in some situations (eg. single-recipient mails). - - - OCSP Stapling support -------------------------------------------------------------- |
