RT 3.8 email delivery options

I’m using RT 3.8.1 on Debian etch.

On the Settings page, I see “Email delivery [Use system default (…)]”.

How do I change that system default?

[Aside: I can’t find anything about email delivery options in
RT_Config.pm or the wiki or a quick google of lists.fsck.com. You know,
RT could really use a manual with basic information that keeps abreast
of releases. I’m aware of the manual on the wiki, but it obviously
doesn’t address 3.8.X; nor does it contain any version or date
information to indicate its applicability.]

What I’d really like to do is suspend email delivery for all users or a
group of users temporarily while I do a large “offline” import of tickets.

I think I’ve asked about this for 3.6, but 3.8 seems to offer
tantalizing new possibilities …

Thanks,
Kevin Murphy

Answering my own question:

Add this to RT_SiteConfig.pm (indirectly if you do it the Debian
package’s way):

Set($EmailFrequency, ‘Suspended’);

(and reload Apache?)
