From: Jeremy Harris Date: Mon, 4 May 2020 21:38:08 +0000 (+0100) Subject: Consolidate $local_part_verified into $local_part_data X-Git-Tag: exim-4.94-RC1~22 X-Git-Url: https://vcs.fsf.org/?a=commitdiff_plain;h=d8024efa365d10d2dba4f06977776f4091250462;p=exim.git Consolidate $local_part_verified into $local_part_data This removes the former; the latter having been around since before the last release. The router check_local_user option now writes the latter and -verified no longer exists. --- diff --git a/doc/doc-docbook/spec.xfpt b/doc/doc-docbook/spec.xfpt index 9336151e5..56c7329ee 100644 --- a/doc/doc-docbook/spec.xfpt +++ b/doc/doc-docbook/spec.xfpt @@ -6381,7 +6381,7 @@ All other options are defaulted. .code local_delivery: driver = appendfile - file = /var/mail/$local_part_verified + file = /var/mail/$local_part_data delivery_date_add envelope_to_add return_path_add @@ -6394,7 +6394,7 @@ traditional BSD mailbox format. .new We prefer to avoid using &$local_part$& directly to define the mailbox filename, as it is provided by a potential bad actor. -Instead we use &$local_part_verified$&, +Instead we use &$local_part_data$&, the result of looking up &$local_part$& in the user database (done by using &%check_local_user%& in the the router). .wen @@ -12550,7 +12550,7 @@ Consider carefully the implications of using it unvalidated as a name for file access.
