How do you like the Xserve? We have found it very hard to get in contact with a account manager at Apple. I would like to get a few to play with. I have called them and they tell us to go down to a local CompUSA. Do you know if they offer 4 hour hardware support like HP does?

Because my particular production environment is using Xserve hardware, and
because that's the OS I'm most familiar with. Nearly all the other XAMS team
members use some flavor of Linux.
John Rudd helpfully suggested:

Thanks for the suggestion, John. I'll take a look at that and see what I can
figure out.
Regarding item [4] below... After looking through the MailScanner code, it
appears that the CustomConfig.pm routines are called from several different
places. It seems that in some cases the ($message) is passed to the custom
routines, and in some cases it is not. So when our custom routine is called
from sendmail2...
sendmail2 = &XAMSTMDAMailer
.for some reason MailScanner isn't passing the ($message) to the
XAMSTMDAMailer custom routine. We can't seem to determine why.
Does anyone have any thoughts on this?
Also, as I mentioned before, it would be great if we could figure out a way
to get MailScanner to successfully run as the "mail" user on OS X. I've
searched the archives, and it seems people on other platforms have
experienced the same problem in the past. I seem to gather that it's been
fixed for most environments, but perhaps not for OS X. Any suggestions for
troubleshooting this would be *most* appreciated.
Sincere thanks,
Justin
