I am receiving scam alerts when opening notification emails from Yii Forum.
How come you define an email address like that? You have yiiframework.com domain, why don’t you use that domain for emails? (e.g. email@example.com, firstname.lastname@example.org, email@example.com)
If you want to use gmail, you can also use google apps that allows up to 10 email accounts for free using @yourdomain.
Receiving from @gmail.com looks very unprofessional for some reason (not to mention the scam alerts because you’re not doing email verification stuff right).
Just my suggestion. Greets.
