User Settable Mail Configuration

Debian developers have a wide variety of loud and conflicting opinions about what constitutes correct handling of their mail, making it impossible for an admin to choose a single setup that fits all use cases.

Instead, we invite you to configure your own spam handling.

Some options available to you are:

bATVToken (to be enabled before 1/1/2010, with any luck) BATV private token for address rewriting. Useful in combatting bounce forgery, but requires configuration on your own mail relay(s).
emailForward Address to forward your mail to. Setting this and then rejecting mail from d.o machines is less than helpful.
mailCallout Whether or not to use Sender Address Verification.
mailContentInspectionAction One of reject, markup, or blackhole. Applies to checks done on the content of message bodies, such as spam and virus checks. Reject is default, and will reject the mail if a match occurs. Markup will add a header and then forward the mail to you anyway. Blackhole will accept the mail and silently discard it.
mailDefaultOptions (to be enabled before 1/1/2010, with any luck) Whether to enable the 'normal' set of (fairly minimal) SMTP time checks that DSA decide are appropriate. Defaults to true.
mailGreylisting Whether to enable greylisting.
mailRBL Set of RBLs to use.
mailRHSBL Set of RHSBLs to use.
mailWhitelist Sender envelopes to whitelist.
mailDisableMessage Absolute last resort measure - will disable incoming mail from all machines not part of the Debian host list (see /var/lib/misc/thishost/debianhosts on any d.o machine). This makes it very difficult for things like automated pings and mass mailings to all concerned DDs about changes to happen, and is strongly discouraged.
