Migrating email is not going to do anything to your apps.
The migration script did not make any requests to your site. It doesn't do that at all. You can clearly see the user agent in the request: "Mozilla/5.0 (Linux; Android 7.0; FRD-L09)"
If you want to migrate your mailbox names and addresses only for yourdragonxi.com then the config you need is:
[email]
include_domains = yourdragonxi.com
include_subdomains = False
The server
setting in the [webfaction]
section of the config is your WebFaction server, which I guess from your examples is web533
in lowercase (as shown in the provided template config).
