I'm a really new beginner with IronPort and more generally with antispam. So you will maybe find my questions a little bit newbee but I need it for understand and improve myself :wink:
First I have a C150 with AsyncOS 5.5.1-014.
I use tagging outgoing mails and bounce verification and for some domains, they failed for delivery.
For example: I send a mail at [email protected] from my adress: [email protected], the client has an antispam which send a mail back to my personnal adress [email protected] with the mail adress [email protected].
What it seems to happen is that [email protected] send a mail to my tagged address (something like prvs=myadress=[email protected]) and is then rejected by the RAT. As I rejected his mail and their antispam wait for a correct answer from their mail, they dropped my mail.
So my questions are:
- When I send a send a mail (which is tagged) to an address [email protected], if another mail adress send me a mail to my tagged address, is this mail considered as a spam ?
- Does the ironport wait that only mail addresses I have send my tagged mail in return with that tag? And to dig a little more, if I received a mail to my tagged mail address I send to another people, will this mail untag and then checked by RAT ?
Thanks by advance and best regards,
