Valid email addresses being rejected. #50
Description
Commit bf276e8 (in attempt to fix #49 ) was able to offer some collective insights on how email addresses are validated. For example, following email addresses are currently being rejected (it exists, and would send out auto replies for now):
email'poc@c86.moe (this is allowed by my email provider, Microsoft 365)
Format of email addresses across the globe has evolved a few times, and with recent developments, also allows following:
dev#ops@example.comdev&ops@example.comdev!ops@example.com"john doe"@example.com用户@example.com
Please consider adjust the regex to at least allow some most common characters, as it would effectively prevent some likely users to use their gravatars.
