Is there a Length Limit on User Email Addresses?

There has been a recent change related to the emails validation during the creation of Sugar Integrate accounts. From now on, the accepted length of the local-part (local-part@domain) may be up to 64 characters long in accordance with the global (RFC) standards related to local-parts.

Please note this change did not affect existing accounts with long emails, but does come into play when creating new accounts or editing the existing ones.
