Custom email id on activation email

Hello guyz,

So i recently took a domain name from forummotion. The issue i am facing is that whenever a new user joins he/she gets a mail from member@forummotion.com. Now i have 10 mail boxes , thats essentially 10 email ids. Is there some way to replace that email id from my custom mail box id ? The current method makes my site really unprofessional ! Please help me out

Thanks

It is standard so you can't change it.

so what we can do to change it? enable auto activation ? or is there a better way ! Please reply

It can't be change as all forums have it and its in the database and we don't have access to it.
