Cannot login to SquirrelMail

Also just to add.

I used to use Windows Server 2008 with hMail server which worked okay and they were delivered.

My Windows Server died though recently so I thought I'd have a bash at using CentOS - I know it can be done - just not sure how to get it to work and unfortunately I can't get my ISP to give me a static IP at the moment which puts me in a bit of a pickle!

The message was sent directly to hotmail and was not relayed trough o2. Please configure o2 as email relay in ispconfig under system > server config on the email tab. Then wait a few minutes and try again.

Hi.

Unfortunately it's not sending at all now to anywhere... I've rebooted and tried again but had no joy.

The relay service O2 offers is relay.o2broadband.co.uk - a username and password is not required however it generally works!

How very odd.

I've sorted it!

I tried relay.o2broadband.co.uk but to my understanding that does not need authentication to send and as far as I am aware ISPconfig does need it to be authenticated.

So I used smtp.o2.co.uk with my username and password.

This worked instantly...

Brilliant!

Thank you for your help Till and Falko.
Greatly appreciated.
