Afaik the period thing is a Gmail thing while the plus thing is in the RFC.
However it appears the IAB UID2 README says to only normalize pluses/periods for gmail.com addresses: https://github.com/IABTechLab/uid2docs/blob/main/api/README.md#email-address-normalization https://github.com/IABTechLab/uid2docs/blob/main/api/README....
- brewmarche 4y agoThere is an RFC but it just mentions + as an example of a possible sub-address separator when discussing sub-addresses in Sieve filters. Whether or not + acts as a sub-address separator is server-dependent.
- jrochkind1 4y agoOh good find, of course they can make a special rule for gmail, which is such a large portion of email addresses it's worth it.
