I'm using Wordpress and sending email via Gmail SMTP:
I created Google Apps main domain called
domain.com and email
Then I registered domain aliases for
I have more different domains/sites:
When I try to send email to
email@example.com from Wordpress site (e.g.
www.domain1.com), it works. If I try to send email to any alias (e.g.
firstname.lastname@example.org), it doesn't. I don't know why.
For your information, if I try to send email from my Hotmail account it works, I can send to all aliases.
