Header check rulesets for sendmail 8.10

Last Update 2000-01-18


sendmail 8.10 introduces even more enhanced possibilities for anti-UBE rules.

Rulesets for Header checks

There is an alpha version (last update: 1999-10-24) of a HACK for the header checks which may give you an impression of the possibilities and problems.

Since this is an alpha version, it's lacking documentation... Just include at least

in your .mc file. See the 8.9 options for some explanations. But be aware: the 8.10 version makes use of some enhanced possibilities like the macro map to store whether the header checks should be activated.
