Re: [AT&T] iPhone accessing IMAP

IGMP is simply a local network discovery protocol, they could be blocking it imap, otherwise call their tech support.

To avoid issues with who-blocks-what, I'm trying to access my IMAP server via the Wi-Fi connection, and I see the iPhone gets an IP address on my LAN, and the logs show the IGMP messages coming from it.

The logs were also showing port 993 traffic was being blocked, which is what makes me certain the iPhone is using TCP 993 to access IMAP via SSL.

It *could* be the SSL certificate, and the IGMP is a red-herring. The SSL cert is "self signed", and maybe the iPhone can't cope with that sort of certificate error. That would suck, but there it is.

I'd really expect it to go through a "the SSL cert is <insert what's wrong with it here>" Do you want to proceed anyway? Yes/No

I'm having the same problem with a self-signed certificate. The iPhone doesn't seem to provide the option to proceed anyway despite the untrusted source. I'm trying to figure out how I can install the certificate on the phone so it considers it a trusted source. That's how I found this thread.
