Options for creating an inbox. An inbox has a real email address that can send and receive emails. Inboxes can be permanent or expire at a given time. Inboxes are either SMTP or HTTP mailboxes. SMTP inboxes are processed by a mail server running at mailslurp.mx while HTTP inboxes are processed by AWS SES backed mailservers. An inbox email address is randomly assigned by default ending in either mailslurp.com or (if useDomainPool is enabled) ending in a similar domain such as mailslurp.xyz (selected at random). To specify an address use a custom domain: either pass the emailAddress options with <your-recipient>@<your-domain>. To create a randomized address for your domain set the domainName to the domain you have verified or pass the domainId. Virtual inboxes prevent outbound sending and instead trap mail.
