Hi Chuck,

That is a good point, Chuck.

No, all in all Mon Chan's setup will not work and only one vacation message 
will be sent. Which is good enough anyway, because why does the sender really 
need to get two vacation messages after sending just one email to one 
recipient?

That's like overkill.

The way it works is this:

The email comes in. The recipient is mon1 at aaa.com. This recipient has an auto-
responder configured AND a forward to mon2 at aaa.com

The auto-responder will happen first. It checks if the sender has already 
received an auto-responder message in the last couple of days. If he has not, 
then the auto-responder message is sent to the sender.

In the next step the .forward kicks in. This happens AFTER sendmail is done 
with the email and forwards it to the local mailbox of the recipient.

The .forward does it's job and delivers a copy of the email to mon2 at aaa.com. 
As this happens AFTER Sendmail is done with the email and the recipient mon2 
is a local user on the same box, the auto-responder will not be triggered. 
Because Sendmail doesn't "see" the message. So it cannot jump on it with the 
auto-responder.

This behaviour cannot be changed, so if you set up a chain of auto-responders 
that bounce messages to each others, then the sender of the email will get 
only one auto-responder message. From the first user that he emailed to.

If the sender sends an email to multiple users with enabled auto-responders, 
then that is a different story and he will get as many auto-responder messages 
as applicable.
