This question already has an answer here:
I have subscribed to mailing lists using Gmail's sub-addressing feature using plus '+' symbol.
The subscribed email address is of the format
email@example.com and I can receive emails on the same address. But when I reply to an email it is sent without the sub-address tag i.e.
The sent message is being held until the list moderator can review it for approval since the list considers it as a post by a non-member to a members-only list.
firstname.lastname@example.org is already a member of the list, is there any way to send emails with the sub-addressing tag?
