iOS Mail and Smoothwall

[dezt]

We have some iPad's that are being used on a guest network, staff have setup their office 365 email accounts through the mail app. When they are at school they can't receive any emails, when they go home they can. We are using Smoothwall as filtering so I think that is the issue, but I can't find any information on what needs to be allowed through the filter to allow the mail app to work.

 

Has anyone come across this issue before that can point me in the right direction?

Mail.App like any other Mail application uses the usual standard ports. SMTP port 25, 143 for IMAP and so-on. If your firewall is blocking these, which is more than likely in an educational institution, then that could be the reason email isn't working? Other possibilities could be User/Group ACLs coming from your AD are not working as they should and possibly blocked certificates? SSL certificate-based email ports are 993 and 995. There's also the alternate submission port 587. Here's the link for Apple's KB for all their ports:
