How to change 'postmaster@domain.com'

Hi,

I have set the max message size on our smtp server to reject those mail message larger than 6M. I’ve tested from Gmail and found that the restriction was work by getting the mail from postmaster@mydomain.com, which told that the size was too large to send.

My question is how can I change the address of this return mail message from ‘postmaster@mydomain.com’ to say ‘itoffice@mydomain.com’.

Thanks for your help.

I don’t think you can, but you can give the other account an alias of “postmaster@Domain.com

Hi Tony,

Thanks for your reply.

In fact, the reason why I ask this question is that in our current situation, the address is

already ‘itoffice@domain.com’, which implies that it really has a way to change the address. But I cannot figure out how.

Any ideas?
