I would need the special pipe transport to be used for everything _except_ bounce/delay notifications. > If the destination is responsible for only a limited number of > domains, No, it should be responsible for everything except bounce/delay notifications. If the default_transport gets broken (as it probably will periodically), then using it for bounce notifications isn't going to work. > it is better to use explicit transport entries for those, and let > bounces, ... go back out via SMTP. > > Do also make sure to get the dot-stuffing (SMTP transparency) 100% > right. -- Grant Edwards grant.b.edwards Yow!
