Hello,

I'm trying to integrate Inbucket into my e2e tests.

The dynamically instantiated VM where Inbucket would run doesn't get a domain name for its public IP address (argh), so my idea was to try out whether I could have my test e-mails sent to somebody@IP_ADDRESS rather than bother with no-ip and such.

I don't want to have the tested application send e-mails directly to Inbucket, but rather via Mailjet (which we use) so that the test is a little more realistic.

Now the thing is that the correct format according to the RFC is somebody@[123.123.123.123]. This format is accepted by Postfix and all SMTP servers I have access to.

Inbucket, however, rejects this format and only accepts [email protected], which is not accepted by anyone else, so it's unusable.

<testtest@[130.61.201.XXX]>: host 130.61.201.XXX[130.61.201.XXX] said: 501 Bad
    recipient address syntax (in reply to RCPT TO command)

Do you think you could extend your domain part validation code to support this syntax?
