Description

Hi,

Would like to create a specific rule (in anonaddy /rules ):

Allow only mails to alias xyz@addy.io from user.name@gmail.com

If sender email does not match user.name@gmail.com -> block the email.

Why Regex?

Some users mail is User.namE@gmail.com, some User.Name@googlemail.com

When I tried it with

(?i)^user\.name@gmail\.com$

And

^user\.name@gmail\.com$

I received

=> the selected conditions 0 match is invalid.

(running latest AnonAddy self hosted)
