Filter e-mails received by SMTP by address

[TM]

Hi,

currently all e-mail that are sent to piler via SMTP are archived.

I’m using BCC for all messages on my mail server to send mails via [e-mail] to Piler. I think it would be nice to have a filter option in Piler to only accept mails arriving on this address.

Hello, I’m confused. Do you send all of your archived emails to my-super….@ address only or other addresses as well?

[TM]

Hi, on my mailserver (mailcow) I’m using BCC maps:

BCC maps are used to silently forward copies of all messages to another address. […]
The local destination will not be informed about a failed delivery.

Therefore a BCC mail is sent to [e-mail] for incoming/outgoing mails. For increased security Piler should/could be configured to only accept e-mails that are sent to this address.

I still don’t understand the issue. Is your archive wide open to the world on port 25, and spammers sending emails to various addresses, but your super secret address?

[TM]

Yes, piler is listening on port 25 to the world. Only security is an IP based access control (simple iptables rule to allow connections from the mailserver’s IP only), but actually I think that is not enough.

OK, I see it now. I’ll add such feature, and let you know.
