#9 Configuration rejects plus sign (+) in email addresses

[Anonymous]

I cannot configure AMTU if my amazon account has an email address with a plus sign in it; for example: somebody+test2@amazon.com.
An email address with no plus sign works (for instance: somebody@amazon.com).
This is under Linux (RHEL5).

The regex in com.amazon.merchants.util.interaction.InputTypeEnum.java:32 is more restrictive than amazon.com usernames. I suggest erring on the side of being too liberal here, since there's already a strong check (an existing amazon.com customer with that email address).
