Hi. I run a site which generates some emails to send out once in a
while. What headers should I set to avoid (or try to) auto responders?
I set

Auto-Submitted: auto-generated

But as far as I can read, I can set the Precedence header also, but to
what value? bulk? list? junk? It's not junk I'm sending out, so I
would not want the recipient service to just drop it.

Anything else I can do on my end?

Thanks.

From the vacation man page:

Checking the To: field is fine for list mail, where it normally
contains the name of the mailing list, but may not be appropriate for
your application. I have never tried setting Precedence: Bulk, and
have never seen any quantitative evaluation of the probability that
bulk mail might be dropped. It might be worth trying.
