Hello @Lilyt17 ,
The ccsend rewrite only affects the From address, not your reply-to address. Automated reply emails like "mailbox full" or "out of office" may or may not be sent to your address, depending on how the receiving email system operates. Contacts that click the reply button in the email program, or who start typing their reply should automatically set in your reply-to address.
For more info regarding the ccsend rewrite, I'd recommend checking out this article.
