Hello.
I have an E-card customer of our site who has sent an e-mail to someone who's
e-mail server is using SPF.
They detected that the sender of the e-mail was not allowed to send an e-mail
from another server (like ours). They request this user to send e-mails only
from one of its allowed servers.
This is problematic for our E-card service, as we force the sender's e-mail
address to be coming from the one the user is typing. We need to do this, as it
allows the recipient to directly answer to the sender, and also because if
there is any e-mail problem, the problem will directly be sent to the sender
and not our server, else the customer would never know of the problem and
wrongly think that the e-mail was sent properly.
Can some one tell me how E-cards developpers should act regarding that matter?
We currently never had any forgery of a spammer who would use our server, and
they are limited to only 10 E-cards per day and per IP address, so it is quite
clean and already very restrictive, and we also check first the sender's IP for
spamlists before accepting the e-mail, this is probably why we didn't have any
problem at all with hackers willing to use our service.
Thanks in advance for any advice.
