How can I sent notifications to external customers

Question

How can I sent notifications to external customer when an event is fired (e-mail address is stored in custom field, say customer-email-address). I know I need to update the notification scheme, but I could not select the custom field, say customer-email-address, so that notification can be sent to the external customer.

As it stands, you can't - this is a feature request that has been asked for quite a bit - see   https://jira.atlassian.com/browse/JRA-2167.  The workarounfd is to write an issue listener that sends emails to the custom field - see http://confluence.atlassian.com/display/JIRA/Listeners for some inspiration.

JEMH uses a TEXT(unlim) CSV separated value custom field to drive notifications to external non-JIRA users.  It also allows those external users to reply back.  Documentation here.
