Re: [spf-discuss] (SOLVED) SPF blocking e-mails coming from an E-card service server

Hello, Stuart.

I hope you added some kind of changing hash token to localpart of MAIL FROM so
that spammers can't use your service as an open bounce relay.

Humm... no not really, and I wouldn't know how to do this.
However I am checking the database to know if the destination addresses are right, and also to know the source e-mail address where it can be the only destination. The spammer should also probide the exact proper ecard ID, which is difficult to guess. I have used a personnalised header (I didn't find any other) 'X-msgid' to pass the ecard ID. I check against this header in the script and with the db.
