Unable to receive emails from outside the network

[Dezigner]

I set up an out of the office auto reply for the Holidays. Have since turned
it off but received no emails while we were away and now cannot get any new
emails. I can send from all 4 email addresses within the network (one to
another within the network) and also send from each email address to an email
outside the network but cannot receive any emails from outside our network.
Any ideas on how to resolve?

What type of mail server do you have?
What happens if you try to send from hotmail/yahoomail/gmail to your
account?
Can anyone on your domain get email?
