Google Apps email : new account for alias domain

Well, here's the very short version of what I learned the other night: if you create an email / GMail account for your primary domain in Google Apps, it takes an hour or two for the same account to automatically work for your alias domain.

Now, the long version....I run all of my email for my kcwebprogrammers.com domain through Google Apps mail servers.  This is done by setting up a Google Apps account and then routing the mail DNS records to Google server specified in your Apps account.  I also have what Google Apps calls a domain alias.  This is another domain that is assigned to the same Google Apps account, but it shares mailboxes with the primary domain.  In other words, if you create a new account / mailbox for the primary domain, then that same account will work on the alias domain too.

So I created a new email / Gmail account for kcwebprogrammers.com, sent it a test email, and it worked.  Then I sent another test email to the same account at the alias domain name, and it failed.  I couldn't figure it out since the Apps help on alias domains clearly says
"By adding a domain alias, you give every user in your domain a second email address (with the alias after the @). For example, if your domain is solarmora.com and you add solarmora.net as a domain alias, every user@solarmora.com will also receive mail addressed to user@solarmora.net."


After looking through all my Google Apps settings, looking through settings on my domain registrar, and even my web host, I did find something else in Google's help files saying that a different kind of email alias could take up to an hour to activate.  So I waited and tried it again the next day and it worked!  I wasted an hour or so looking at settings and help files, but as my wife reminds me, at least I learned a few things.
