[BlueOnyx:00577] Strange BQ Sendmail behavior - fixed in BO?

[Jeff Jones]

Hi BO-mrades,

Had a re-occurrence of an age old issue with one of my BQ boxes today,  
and as I am soon to migrate this to BO - I was wondering if I'm going  
to be in for the same fun and games?

But it's highly likely that something went screwy with BQ - I would  
just like to understand why it happened so I can perhaps avoid making  
the same mistake again.

So I have a site - yes it's www.foo.com (you wonder why these guys are  
still customers - they have so many problems) but it's just a website,  
there is no email locally. I checked the 'disable email for domain'  
checkbox on the site - so I think it's all cool.

Next thing I know the boys at www.foo.com are on the phone, saying  
that email from the website (via php mail) is bouncing. I take a look  
in the mail logs, and sure enough I can see "contact at foo.com - user  
unkown". So I figure out that email from the site is trying to be  
delivered locally, even though I have checked that 'disable' email  
check box for the site.

Struggling for a solution - I take a look in /etc/mail and look at the  
access file. I see the following:

### Start Block Email for Virtual Site: www.foo.com   ###
www.foo.com             ERROR:5.1.1:550 User unknown

### END Block Email for Virtual Site: www.foo.com  ###

I then manually change it to this:

### Start Block Email for Virtual Site: www.foo.com   ###
www.foo.com             RELAY

### END Block Email for Virtual Site: www.foo.com  ###

Restart sendmail - and hey presto - foo.com are getting email from the  
site again.

So I've found a work around - why am I bugging you all?

I guess I'm worried it might happen again with BO - could it?

How / why did this happen?

It's a real drag!
