I have this concept on mind:
Now suppose that the IMAP User Name is "bounce@try.com" and the Mailing List has in the field From Email the "from-email@try.com" email address:
If you send the newsletter from "from-email@try.com", and you have configured bounce@domain.com has the email to get bounced emails, how bounced emails are going to arrive to "bounce@try.com"?
If an email is rejected, it´s always rejected to the sender (I think)
Now suppose that the IMAP User Name is "bounce@try.com" and the Mailing List has in the field From Email the "from-email@try.com" email address:
If you send the newsletter from "from-email@try.com", and you have configured bounce@domain.com has the email to get bounced emails, how bounced emails are going to arrive to "bounce@try.com"?
