I have several email accounts with my webhosting provider:
Ex:
webmaster@ProjectA.com
webmaster@PlanB.com,...
And a default systematic email , say,
accountname@mywebhost.com.
When a user registers an account in my wiki site, all mails are sent from the default email account
accountname@mywebhost.com.
Actually, they should be from
webmaster@PlanB.com.
So, how can I change?
