From 28b5b23c285511431923f22263f00ed0e5c19c1c Mon Sep 17 00:00:00 2001 From: Guilhem Moulin Date: Thu, 11 Jun 2015 16:35:31 +0200 Subject: Don't bounce unverified recipients upon 4xx errors. We don't want to bounce messages for which the recipient(s)' MTA replies 451 due to some greylisting in place. We would like to accept 451 alone, but unfortunately it's not possible to bounce unverified recipients due to DNS or networking errors. --- roles/MSA/templates/etc/postfix/main.cf.j2 | 3 +-- 1 file changed, 1 insertion(+), 2 deletions(-) (limited to 'roles/MSA') diff --git a/roles/MSA/templates/etc/postfix/main.cf.j2 b/roles/MSA/templates/etc/postfix/main.cf.j2 index 331753a..068a225 100644 --- a/roles/MSA/templates/etc/postfix/main.cf.j2 +++ b/roles/MSA/templates/etc/postfix/main.cf.j2 @@ -98,8 +98,7 @@ strict_rfc821_envelopes = yes smtpd_delay_reject = yes disable_vrfy_command = yes -# UCE control -unknown_client_reject_code = 554 +unverified_recipient_defer_code = 250 unverified_recipient_reject_code = 550 smtpd_client_restrictions = -- cgit v1.2.3
