Incomplete email constraint

[nixonwidjaja]

• In the constraint, only local-part can contain special characters +_.-
• However in practice, many domain also contain these special characters, e.g., mercedes_benz
• Your app does not allow customers from mercedes_benz domain.

Team's Response

By our current constraints, it complies with the stated constraints, hence, it is not a functionality bug.

Even if it is a feature flaw, according to RFC 1035 page 8, underscore and other certain special characters are not included in the allowed characters in the domain in https://datatracker.ietf.org/doc/html/rfc1035.

Team chose [response.Rejected]

• [x] I disagree

Reason for disagreement: https://stackoverflow.com/questions/2049502/what-characters-are-allowed-in-an-email-address

I agree that this is a feature flaw. However, based on the article above, hyphen is allowed in email domain. Therefore, my argument stands that the app does not accept domain names that have hyphens, for example, and thus is a feature flaw because it cannot accept all valid emails.
