DCC headers vs. Symmantec antivirus conflict

Hi,

We've recently got many bounced messages from sites running the
symmantec antivirus gateway. The error messages were about MIME
header parsing error. By some experimenting i've found that the
DCC header line causes the trouble:

X-DCC-x-mailer.co.uk-Metrics: mailfilter 1192; IP=ok Body=1 Fuz1=1

If i replace the dots by dash (X-DCC-x-mailer.co.uk-Metrics: ->
X-DCC-x-mailer-co-uk-Metrics:) then it works fine!
So i think that using dots in mime header names is invalid by
(some) RFC, so some paranoid scanners/gateways catch it?

The real question is how to solve the problem.
Either DCC servers should be forced not to use dots in name,
or the dcc-proc client should be fixed to replace dots by
some valid characters.

Any ideas?

please Cc: me, i'm not subscribed to this list. Thanks.
