I am trying to add an email address to Google Voice to forward SMS messages to a push server. The email address is a generated token which is 89 characters. Although we can refactor this token down to lesser characters, I am interested to know what the max length an email address can be for Google Voice.
I've read that the the max email address is 320 characters, but apparently either this is inaccurate, or Google Voice has a different restriction.
Local address or username (the part before the @) = 64 characters Domain name (the part after the @) = 255 characters @ sign itself = 1 character
64+255+1 = 320.
