Why won't iPad connect to my mail server?

I have just got an iPad and tried to set up my mail server.

I have a server that has SMTP on port 25 and IMAP configured on the default port 143, nothing special.

In addition, I have port 144 for secure IMAP and 26 for secure SMTP. SSL is a self signed certificate for a custom root that is installed in all devices that allow it.

I use SSL exclusively here and every laptop, desktop and other device works fine with it.

I first tried to set the iPad up with this, but when it did not work, I deleted the account and tried the non secure standard 25/143.

After main attempts (and failures) I did discover that I can send messages fine on both standard and the secure SMTP (indicating no problems with the SSL certificate).

I turned on logging on my mail server and found the message

TCPConnection - SSL handshake with client failed. Error code: 2, Message: End of file,

I get this when trying both SSL on and off.

I tested it on an iPod touch that was here and it works fine on both Imap Secure and standard.

Thanks in advance!

I found the enterprise tool, and managed to pull a log. I have cleared the log, then go in to mail and the following occurs:

Straight after the last line, the device flashes the "Cannot Get Mail" message.
