Google is at it again

[Stephen Satchell]

I have a crontab set up to send me regular reminders on my local mail 
account.  I've added reminders for a person with a Google mail account. 
They haven't been getting the reminders lately.

By doing some testing, I found that Google was silently rejecting mail 
from my workstation.  The fix was easy: configure relayhost in PostFix 
on my workstation to send mail through my registered mailserver.

I know this is basic Postfix-fu, but I'm sending this little, um, 
reminder to the mailing list, in case someone else has been scratching 
their head over mail to Google being black-holed.
