[BlueOnyx:26496] Re: The Postfix learning curve continues

[Chad Bersche]

Thanks for the explanation, Michael.

Most of the challenges are, honestly, coming from other solutions that 
send telemetry, etc. both to local admin (i.e. me) and for remote 
diagnostics/statistics.  The emails that are going to domains hosted by 
my BlueOnyx, as you'd expect, get delivered just fine.  It's those pesky 
outgoing things (and to be honest, I also use internal email to external 
SMS notification emails for some things that also get shot down).

While none of these are life and death critical, I'm glad to know that 
at least the problem is understood, and appreciate the complexities of 
implementing a fix.  Hopefully parsing the IF{postfix} then {ensure IP's 
only} won't be a big lift, and also won't disrupt anything else that 
needs to work.  I respect that my challenge may be a specific to me one, 
and that doing something about it may not be practical without breaking 
other things.  If that ends up the case, just tell me. :)

Thank you sir!
