Can not send/receieve e-mails but connected to Internet

[georgeki]

Hello out there.

All of a sudden last evening (without touching absolutely any settings, as I am a new Mac user) my Entourage 2004 mail application (while I was logged on to the internet) could not send/receive e-mails, giving me the following message: 'Internet Connect: The selected communication device does not exist. Please verify your settings and try again'

I tried several times repeating the task, quiting Entourage, etc without any sucess at all.

Can someone please tell me how I can overcome this issue??

Many thanks in advance!!!!

If you don't tell us anything about your ISP or your email settings, then we can't help you.

You are right!

I've setted up a POP3 account and I am using one provider for receiving mails and a second one for sending e-mails.

And for all this time I had absolutely no rpoblems at all!!!

It all started since last evening!
