Hi, we have cpanel server that is on WHM 11.32.4 (build 14) running Courier as our mail server. We have iphones configured on various domains on this server to use IMAP and those email accounts have been working fine from iphones with IOS5 on them. Some of our customers have upgraded their phones to IOS6, and their cPanel IMAP email accounts stop working on their iphones. No amount of fiddling with the account settings will get the account to work again. They cannot send or receive from the account any longer. They receive the message "can't connect to server". We are finding that they have to delete their account and then set it up again. With the exact same settings and then they work again. Is anyone else experiencing this problem, or any ideas on how to further troubleshoot this as I'm sure it is going to happen more frequently soon. Thanks.
