Github dislikes email “aliases” so much that they will shadow ban your otherwise normal activities for months, and once flagged, support will request not only a “valid” email domain but also that you remove the “alias” email from the account completely.
Basically another email address that forwards everything to your main email.
How would they even detect that? Blacklist common alias providers?
I dont think so. I get my self hosted aliases banned. They must read the dkim/spf/dmarc or other types of headers against a base of mainstream email providers
Wouldn’t that ban self hosted email period?
Depends on what header they read and how
I guess so
