I am newly enrolled, incoming emails not working

Dear Team,

 

I have recently enrolled my domain with you as allied-computers.com

And created email account admin@allied-comptuers.com it is working fine with sending emails but its incoming is not working.

 

Please advise and do the needful asap.

When I try sending email from any account, it bounces back with some permanent error failure.

 

Request you to please do the needful on immediate basis and respond.

 

Regards,
