suitecrm: can/should we delete orphaned E-mails and SecurityGroups?

[jonathanmaw]

It's possible to delete these using the SuiteCRM HTTP API, but we're not 100% certain whether doing so would break something.

e.g. if we delete a SecurityGroup then we'll have to manually re-add roles to it.
e.g. are E-mail records used in places other than Users, that will break if the E-mail record is removed when the user is?

Actually knowing whether these are unused will be difficult - querying an E-mail address doesn't list all the places it is used (though it's possible SecurityGroups might list all the places they are used)
