Restrictive Email Validation
My email is a@firstnamelastname.com. Often it isn't permitted when signing up to services. So I use a+[servicename]@ instead.
Why is this so? I've never seen/written validation rules before so I don't know why this happens.
Any other examples of regularly rejected email addresses?
- mytailorisrich 7y agoIt seems highly likely that someone took upon themselves to decide that a single letter before the @ was not a valid email address (it is). Many email validation functions/regex are also often simply copy-pasted from a google search and poor validation spreads that way...
