I have an email address that sends to five people using a virtual-map line:
tinyl...@example.com m...@example.com, t...@example.com, (etc) When tinylist receives email, header_checks uses the following test to add a reply-to line to the header, so that replies go to 'tinylist' rather than the original sender: /^To: .*tinylist@example\.com/ PREPEND Reply-To: tinyl...@example.com For mail from three of us, that works fine. Two people's mail clients have already added a reply-to line in the header, so two reply-to lines end up in the header: (etc) Delivered-To: m...@example.com Reply-To: t...@example.com Subject: Re: Some stuff Reply-To: tinyl...@example.com To: tinyl...@example.com (etc) .. which is contrary to the relevant RFCs and, worse :), means that everyone else's client only looks at the first one when deciding where to send replies. How can this be avoided while maintaining the simplicity? Thanks, Ian
