This looks like the best bet to me. Especially if the AV processor
charges by the message: perhaps you can reject or approve before
submitting to the AV. ;-)

I'm not saying I agree that an A/V company is right to put their tagline into
the message, especially if it breaks DKIM. If I owned an A/V company, I
wouldn't do it [1].
However, I understand why A/V companies would do it - it (presumably) helps

And
Er, what I meant was this:
Having the "Virus scanned by xxx" ***in a header*** defeats the purpose of
advertising since most clients won’t display it. A/V filters put those taglines
in there to advertise, not just to tell the mail client that their mail has

How will most mail clients know not to display it if it's made part of the
body?

Having the "Virus scanned by xxx" defeats the purpose of advertising because
most mail clients won't display it, and the point of adding this to the body is
so that other people can see it. I think Murray's earlier suggestion to perform
the DKIM check before A/V filtering is the best option.

They break DKIM signatures on incoming email by adding a "Virus

Though I would never put such a thing in a standards document, OpenDKIM
does have the capability to rewrite arriving header fields prior to
signing/verifying to overcome things like this. Your ESP's verifier could
be trained to ignore the added line prior to verifying, or better yet, do
DKIM verif
No it's not at all a free service. But they advertise anyway :-(

In this case it's not a header, but a line added to the body of the email

Henrik,
I think that the fact of virus scanning is more commonly just another
header in the message, which would not break a properly created
DKIM-Signature.
For example your message (via the list) got to me with extra headers
such as: X-IronPort-AV, X-IronPort-AS
Perhaps that example from an
In Denmark we have a somewhat large (10K+ domains) anti-virus/spam provider
