Setting up my mail account on my iPhone. I was able to get mail to send and receive using IMAP - I had to open up the following ports on my router and forward them to the internal IP of my server:
25 Incoming mail
80 Incoming /webaccess
143 Incoming IMAP
443 Incoming https
587 (Im told its used for exchange, may not even be needed)
993 SSL port for incoming mail
Now, I want access to the calendar and contacts, so I'm trying to set it up as an Exchange ActiveSync account. No dice. Have no idea what I'm doing with this one.
Anyone have better luck? I could try on Outlook as well, just need to know what I have to do on Zentyal to get that part working.
