Hi, is there a contact from Bluehost.com available here? I'm having difficulty
determining the cause of a blacklisting that they're applying to us.

Thanks to the responders showing different limits, reminding me to RTFM
and check the default configs of some other products :-)
In

you see that 32KB max header size as a sensible limit in today's conditions?

when we got dsn=500 from Proofpoint we noticed the issue, and requested
delisting.
This went through, then our queued items got delivered, triggering a

The feedback loop to the sending IPs is the problem, common to so many
other reputation providers.
