Only Warning: Users with misbehaving auto-responders will be kicked off the SPF mailing lists

Dear subscribers to the SPF mailing lists,

as the list moderators have been plagued for years now by automatic replies 
sent by the auto-responders of inconsiderate subscribers, these mailing 
lists' policy on the tolerance of such auto-replies is about to change, 
effective immediately.

Auto-responders sending automatic messages (such as vacation messages) in 
reply to mailing list messages (be they directed to the message's author 
or, worse, to the entire mailing list) constitute rude and anti-social 
behavior, as they harass the list's subscribers, or even pollute the list, 
with irrelevant information.  From now on, if your auto-responder gets 
caught sending auto-replies to postings on the SPF mailing lists, your 
subscription will be deactivated until it has been demonstrably fixed.

This is your only warning.

Such mailing list postings can be recognized from a "Precedence: bulk",
"Precedence: list", or some "List-ID:" header.  If you haven't already, go 
teach your auto-responders.

The most prominent example of such misbehaving auto-responders has a
"X-MimeOLE: Produced By Microsoft Exchange V6.5" header field.  Be advised 
that Exchange's auto-responder not being easily fixable is not an accep- 
table excuse.

Julian.
