[Q] Need help to intall Stock Email.apk in custom ROM

Hello Dev / Members,

I Flashed a ROM (Xperia_Z ROM for Note N7000 by AmniX). It doesn't have stock Email.apk in it. I tried to push "secemail.apk" in /system/app and set the permission to rw--r--r, apk is getting installed, also showing the Email icon. But after putting my email ID and passwords, it shows only one message "Trying to communicate with Server" and keeps on showing until I click cancel. I waited for more than an hour (Seriously more than an hour). In parallel other email clients are working but those are free and having some limitations.

My Question is, After installing Email.apk, is there any other file (probably which I'm missing) which sync with the servers ??? May be that file is missing in that ROM. I know its not a problem with ROM, as other free email clients are working.

Please Help.

Thanks
