There shouldn't be any risk of loop.  You get past isLocalHost, then you 
notifySender... that message is sent to john@james.com with a sender of 
<>, because it is a server-side generated notice.  This message then 
gets sent to you, it again goes through and fails isLocalHost, and then 
reaches notifySender which will swallow the message since it can't send 
a failure notice to <>.

I don't know how to configure the notify sender mailet off-hand, but 
that's logically how this situation is resolved.

RE: Configuration Issues

[Alan Gerhard <al...@GerCom.Com>]

thanks Serge, that makes sense ...

but -

i must have done something wrong with the configuration or something.
i have 1,825 mails, more or less addressed to a user that does not exist - from
that user.
obviously a spoof and spam, but what seemed to happen was that james20A3 went
into a loop and these 1825 just got bigger and bigger - and with the dat files i
was looking at close to 200,000 plus files on a WinTel box and james really
didn't like that.

the following is an example of what was being generated - and the logs have been
trashed (version 20A3) but this seems to be the pattern.

with your explanation, the return-path should be empty, right ??

anyway, was just wondering if any of you guys know what might have went wrong so
i can prevent this from happening again.
tnx ...
