“自定义入站电子邮件地址”的限制（可能仅适用于托管站点？）

[supermathie (Michael Brown)]

@BradCray

would it be possible to have the hosted instances generate a warning or error if the email address was not of an expected format?

There is no bound to the “expected format” other than “valid email address”, so this isn’t feasible.

@BradCray

or an expected format when using a …discoursemail.com address?

This might be something we could do.
