It's slightly more complex than "accepting those that exceed the max": The RFC says that a user-part should not exceed 64 bytes. At the same time, it says that server should try not to impose limits if possible. While at the same time, some particular limits must be imposed to avoid issues when exchanging with other software (ie: the length of a header or data line). So basically, we should disregard the arbitrary 64 bytes limits if it is possible, but we're still bound to limits we cannot disregard, and which are completely unrelated to the email address itself... We decided to bump to an arbitrary 255 bytes limit for the user-part and 255 bytes limit for the domain-part. An email address can be at most 511 bytes with today's code. > > People using SMTP have been assuming infinite size in email addresses... > > I see.
