Considered UNSOLICITED BULK EMAIL, apparently from you

[NickFitz]

So, it seems that it was just a faked header, in which case, SPF should help (??) because the SPF record indicates that the mail is of fake origin. True?

Probably. TBH I just ignore that stuff - it usually subsides after a day or so.

Assuming your FormMail.pl is only used to send stuff to you, you can hard-code your email address in the script rather than taking it from query parameters, and then it can't be used to email anyone else.

The headers of the bounced spam should allow you to see where it originated. The message you quote seems to think it came from AOL, so unless that's the SMTP server used by your script, that won't be it.

Thanks, Nick.

The addresses are hard-coded into FormMail.pl (there are several options, contact person A, contact person B, etc).

AOL isn't the SMTP server used by my script.

My website includes a "response form" which uses FormMail.pl, which I thought is secure.

How can I tell if the email originated from my website via FormMail or is simply a bogus "reply address" in the header?

Thanks!

I don't have an issue with backscatter - I get one of these "bounce" messages every month or so, not hundreds per day.

And if my FormMail.pl has been compromised (???) then as far as I can tell, an SPF record isn't going to help, as email will originate from my domain.

Sorry if this sounds ungrateful - certainly not - I'm just trying to understand the issue!

TIA.

No worries, you're correct in that SPF won't help if FormMail.pl is the culprit as the SMTP relay will be valid according to the SPF record.

Does the form mail do any logging?

Configuring an SPF record against my domain did the trick for me - pretty much solved my backscatter issues overnight.

I received this notification today.
Is there anything I can do about this? i.e. stop people abusing my email address?

Is this just email provide by your ISP or do you have mailers on a website? If latter, I could suggest some secure scripts that appear to work.

A message from <Platypus> to:
-> Platypus

was considered unsolicited bulk e-mail (UBE).

Our internal reference code for your message is (blah blah)

The message carried your return address, so it was either a genuine mail from you, or a sender address was faked and your e-mail address abused by third party, in which case we apologize for undesired notification.

We do try to minimize backscatter for more prominent cases of UBE and for infected mail, but for less obvious cases of UBE some balance between losing genuine mail and sending undesired backscatter is sought, and there can be some collateral damage on both sides.

I suspect not.
