From 45743fcc30ad310da0ef306d6319face3604ac4d Mon Sep 17 00:00:00 2001 From: Guilhem Moulin Date: Mon, 15 May 2017 23:31:13 +0200 Subject: Use blackhole subdomain for sender addresses of verify probes. MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit These addresses need to be accepted on the MX:es, as recipients sometimes phone back during the SMTP session to check whether the sender exists. Since a time-dependent suffix is added to the local part (cf. http://www.postfix.org/postconf.5.html#address_verify_sender_ttl) it's not enough to drop incoming mails to ‘double-bounce@fripost.org’, and it's impractical to do the same for /^double-bounce.*@fripost\.org$/. --- roles/MX/files/etc/postfix/virtual/reserved_alias.pcre | 3 +-- 1 file changed, 1 insertion(+), 2 deletions(-) (limited to 'roles/MX/files') diff --git a/roles/MX/files/etc/postfix/virtual/reserved_alias.pcre b/roles/MX/files/etc/postfix/virtual/reserved_alias.pcre index 9fe60c8..eb17d65 100644 --- a/roles/MX/files/etc/postfix/virtual/reserved_alias.pcre +++ b/roles/MX/files/etc/postfix/virtual/reserved_alias.pcre @@ -2,5 +2,4 @@ # For other domains, RFC 822 section 6.3 and RFC 2142 section 4 # mandatory aliases are forwarded to OUR admin team and to the domain # owner or postmaster, if there are any. -/^(postmaster|abuse)(?:\+.*)?@(.*)/ $2/$1@reserved.fripost.org -/^(double-bounce)(?:\+.*)?@(.*)/ $2/$1@discard.fripost.org +/^(postmaster|abuse)(?:\+.*)?@(.*)/ $2/$1@reserved.fripost.org -- cgit v1.2.3
