	I can understand your frustration, but taking it out on me isn't 
going to help you solve your problem any sooner.

	Try putting the fully qualified domain name in question into your 
$mydestination list.  Postfix should then recognize the domain as 
local and not something to be delivered via SMTP.  This is explained 
on the page above.

	However, the author of that page spent a lot of time putting 
together examples to make the description of the problem more 
concrete, so that he could better explain the problem, and better 
explain the solution.

	Having looked at your entire post yet once again, It sure looks 
that simple to me.  You've got the following $mydestination defined:

		mydestination = $myhostname, localhost, localhost.$mydomain

	From looking at the log entries you quoted, I presume that your 
$hostname may be "chandler".  I hope that you've got $mydomain set to 
"sharp.fm".  However, you do not define $mydestination to include 
"$myhostname.$mydomain", although you do include "localhost" and 

	The fact that you might require $mydestination to include 
"$myhostname.$mydestination" should have been obvious by reading the 
documentation, and the page I quoted.

	It is fundamentally *not* a problem with Mailman, or an 
integration issue between postfix or Mailman.  If it was, I would 
have given you a lot more leeway.

	This is clearly a pure postfix problem.  Even if I'm wrong in the 
solution that I recommend, I am quite certain that this is a pure 
postfix problem, and has absolutely nothing to do with Mailman.

	This is why I said:

		This is a postfix configuration problem.  I would recommend
		checking the Postfix FAQ, and the archive of the postfix-users
		mailing list.

	I see nothing here that would be considered to be inflammatory.

	Your response was:

		Already did to no avail, which is why I am now asking it here
		in case anyone here has ever run into this.

	However, the problem is that this mailing list is intended for 
the support of Mailman, and a lot of people on the list do not use 
postfix.  Asking us to support postfix as well as Mailman is not a 
good idea, and detracts from the main purpose of this list.

	You need to use the resources which were intended to support your 
non-Mailman problem, and not abuse us to support a program which is 
not our focus.

	And yes, although I understand your frustration, you are getting 
rather abusive now.  You're not only abusing the list to support a 
program other than Mailman, you're being personally abusive towards 
me because I'm trying to get you to take the problem where it really 

	To be honest, I should not have attempted to provide any kind of 
a solution for you.  But at this point, I basically just want the 
abuse to stop.

	The next time someone asks us to answer postfix questions, 
they're going to get a lot less help than you have.  That's a pity.
