OS X El Capitan Server - search function

[nickologic]

I recently upgraded OSX Server from Yosemite to El Capitan. Mail is being hosted on this server.  Ever since I did the upgrade users are unable to utilize the search function in round cube. I am wondering if there is anything I have to change in the round cube configuration to make this feature work again.

I am running round cube version 1.1.2 and I did a separate install of 1.1.3 which still has the same error.

Thanks

Its going to be a configuration option on your mail server not Roundcube.
