Ask HN: Case sensitive email provider?
Does anyone know of a email provider that treats the email username part of the address in a case sensitive way? e.g <username>@domain.com
- bradknowles 7y agoThe RFCs are very specific that e-mail addresses should be case preserving but not case sensitive. What is the use case here for violating the RFCs?
- shusson 7y agohmm my understanding of Section 2.3.11 [1] was that the email username must be case sensitive. What part of the spec states that it is not? [1] https://tools.ietf.org/html/rfc5321#section-2.3.11 https://tools.ietf.org/html/rfc5321#section-2.3.11
