rfc2822 implies multiple ReplyTo addresses should be supported. From: https://www.ietf.org/rfc/rfc2822.txt "When the "Reply-To:" field is present, it indicates the mailbox(es) to which the author of the message suggests that replies be sent."
But setting the ReplyTo property to multiple addresses (e.g. "firstname.lastname@example.org,email@example.com") doesn't seem to work in later versions of Chilkat. The Reply-To header in the eml file gets set only to the first address.
How can we set ReplyTo option to multiple addresses?
~~Try semicolons between email addresses - seems to work here to preserve multiple addresses in the header, though I'm not sure if this is valid and will be considered multiple email address, or just a single address.~~
