From 6d5d22525545fb6096e85e43de20cc77a4d6a509 Mon Sep 17 00:00:00 2001 From: Melvin Vermeeren Date: Wed, 20 Sep 2023 17:28:53 +0200 Subject: [PATCH] Implement Reply-To header support when replying The Reply-To header, if present, will take precedence over the From header. If the Reply-To data is undefined old behaviour is used. Note that Horde libraries appear to internally determine reply_to property in the Horde_Imap_Client_Data_Envelope (unless Dovecot does it, but doubt). It was observed that reply_to property had the same value as from property in a mail that contained no Reply-To header. It is assumed that the Horde implementation makes sense, so just use the value as-is. This notably fixes replying to mail from software reliant on the Reply-To header such as GitLab and GitHub notifications and many types of mail based ticketing (support) systems.
