Trying to use a public accees WiFi hotspot provided by a corporate for customer and staff use to get email and general Internet access.

Normal web browsing works fine on the connection but I encounter this strange issue with e-mail.

Using a standard email client (I tried Typeapp and Mail) on Android and also Typeapp on IOS setting up the client as per the server specs viz 993 for IMAP and 465 for SMTP the email headers download fine but as soon as I access an email to see the body of the email I get a connection error. Also cannot send mail via SMTP. The same configuration works fine when the internet connection is my home WiFi or a tethered iPhone.

Interestingly if I try Outlook for Android and let Outlook work out the email settings directly from the domain name it works fine. I would continue to use Outlook but that app is broken in terms of displaying messages from GZ and apparently other sites in terms of embeded URL's. URL's look selectable (like links to GZ forums) but they are not. This is apparently a bug in Outlook.

I've tried explaining the problem with Tech Support but all they say it, it works for us (i.e. they can access the web or FB from their mobile devices).

Anybody have any insights into what could be happening here? I would not hae thought that once you can see the email headers there would be a different protocol for downloading content unless there is some strange content filtering going on.

I know there are some hotspots out there that redirect all smtp traffic through their own smtp server, and possibly other ports too.

SMTP is only issue. What puzzles me is that on 993 the client can download the mail headers including subject lines but as soon as I try to download the body of the email I get connection error. And then the question why does Outlook work?

Regarding Headers only, I struck this once when a user had 'inadvertently' turned the "Headers Only" switch on ... Outlook has this off by default, so maybe check your email client/s for this?

If you're using a secure connection and the hotspot is redirecting secure ports it will cause certificate errors

No the setup works fine on other WiFi networks. Just as soon as I connect to this corporate one then email bodies don't download and SMTP fails. It just puzzles me that Outlook works but the Outlook app doesn't expose the actual server settings - it worked them out from the email address (not Gmail).

i just checked and the Gmail client works on my Gmail account but if I add my other non Gmail account it fails.It must be something strange with my email server and this particular firewall.
