When I configure my Xperia Z1 Compact (OFW 4.4.4) with EAS (Exchange) mail type account I only receive messages in plain text.
If I use IMAP for the same account, the messages arrives with no problem in HTML format.
I have made some reading and Sony indicates that is not a problem of the phone, but a bad implementation of S/MIME on server side, I'm using the latest version of ICEWARP mail server with full implementation of EAS 14.1
I have no problem with others phone also using 4.4.4, only with Xperia Z1 Compact.
Thanks for your help.
