SpamfilterN final MTA options

Spamfilter MTA options:   (bitmask)
Some filtering libraries have the ability to perform a set of actions based on recipient addresses. What sort of recipient address is passed to the filtering library depends on the setting of the respective    (N=1-8) MTA option. The default value of 0 results in a so-called intermediate address being passed to the filtering library. This address is suitable for use in delivery status notifications  and for directory lookups of local users. If bit 0 (value 1) of     is set, however, the final form of the recipient address is passed. This form may not be suitable for presentation, but is more appropriate for use in subsequent forwarding operations. The      MTA options are only available in MS 6.0 and later; iMS 5.2 behaves as if the option had the default value of 0.

In MS 6.2 and later, bit 1 (value 2) of    controls whether or not source routes are stripped from the address that&#x27;s passed to the filtering interface. Setting the bit enables source route stripping.

In 7.3-11.01 and later bit 2 (value 4) of  , if set, causes the "initial" address to be passed to the spam filter. This is the address that was initially passed to the alias expansion process. Bit 1 can be used to strip source routes from such addresses if desired.
