I regularly send announcement emails from within Gmail to a Google Group that I manage, using a 'send mail as' address rather than my primary account address. When group users reply to a message, they are always sent to my primary (Gmail) address rather than the secondary 'send mail as' address via which they are sent. This is true irrespective of whether or not 'treat as alias' is selected in Gmail. How can I ensure replies are sent to the 'send mail as' address rather than my primary Gmail address?
N.B. This isn't an issue when sending emails to individual addresses rather than a Google Groups emails, but I've tried it with two different Gmail account and two different Google Groups and get the same issue with both.
