It’s interesting that the subject turns up here, when there is a fresh (and good IMO) blog post out about email address validation out, "Your E-Mail Validation Logic is Wrong" https://www.netmeister.org/blog/email.html <https://www.netmeister.org/blog/email.html> by Jan Schaumann It’s worth reading and perhaps pointing to when complaining to said postmaster.
