I have my own email server (Dovecot+Postfix), which is hosted on the same server as my portal (Centos 6.3) and I have installed squirrel mail client and it is working fine with but branding it is not easy also embedding it in my web application is not easy.
I have been through the internet and I found different other web based clients as roundcube, but unfortunately it is not clear with all these variates which one is easier in:
1- Flexible branding
2- Embed it in my web application (It will be great if any has a jquery plugin).
Any advice please?
