Email as login: handle plus '+' aliases properly

Related products: Online account

Some customers may use site-specific email aliases like name+site@domain.tld for increased efficiency and security when signing in to account.ovoenergy.com. 

OVO’s email system currently distinguishes between an alias and its underlying address. This means that email sent from name@domain.tld is not recognized as originating from the user whose login username is, say, name+ovo@domain.tld.

I suggest that this be changed. 

I had not come across this before (which I thought unusual) but it does sound a good idea. How long have you been using this technique @Firedog ? and do most sites deal with this as you would expect?


As an example, cPanel has supported it for years via cPanel Webmail, especially when using Roundcube rather than Horde. It can even automatically create folders in Roundcube whenever a new + address combo is detected for the first time.


The technique has been around for many years, but I probably only started using it consistently and effectively around 10 years ago, when Outlook finally started handling plus aliases properly. OVO’s is the first site I’ve come across that fails in this respect. There have probably been others that simply don’t allow a plus alias to be registered as a username (“Please enter a valid email address”). 


I can't imagine i would ever use it personally, although i have voted for it as i can see how some people would find it useful 


Yep to me this is a good feature request and something I’d like the product team to see. Opening this up for votes
