Aruba Instant 'guest' network blocking e-mail

Hi

 

We have setup a 'guest' wireless network for a customer using Instant 'guest' setup.  We are using the default VLAN (3333?) and using the internal DHCP / NATing, etc.

 

Internet connectivity works fine but users can not access e-mail on thier devices.

 

We have the following on the Aruba firewall

 

DNS Allow

DHCP Allow

HTTP Allow

HTTPS Allow

POP3 Allow

SMTP Allow

PP2P Allow

Allow Application Category Mail Protocols

Allow Application Category Webmail Protocols

Deny Everything Else

 

Any ideas?

 

Thanks

David
