CiviCRM Community Forums (archive)

I am using 1.7 with CiviMail. I have "Forward Replies" checked in my mailings. When the mailing gets sent out, the return address ends up being something like this (two examples below based on the person receiving the email):
reply.1.11.39.8c8331e8206641c5efa93ae3b37fa78bf4a03519-newslettr=mydomain.org@dev.mydomain.org
reply.1.11.38.43751b6bca6b709441017bb74f3be74318ce9840-cstanly=mydomain.org@dev.mydomain.org

Two questions. First, I have tried doing a reply-to from all the people's email addresses who received the mailing I sent out (to a test group). The only email that seems to have actually been delivered is when I reply from the same email address that originally sent the mailing. For all others that try to do a reply-to, the emails appear to be lost in the ether....can't find them anyway.

Second, the end of that string is confusing me (dev.mydomain.org). The dev.mydomain.org address is from an old server. I have migrated CiviCRM to a completely new server. I don't understand why that address is coming through. Where does it pull that from?

Thanks,
Emily
