Menu access to roundcube use ip not shared ip

I have a tiny problem for Roundube's menu url.

The roundube url access be "public ip", not "shared ip" (example: http://66.66.66.66/roundcube) and this cause this problem:

FSL_HELO_BARE_IP_2 (This problem is caused by wrong HELO)

how can i change the menu url?

at the moment links can't be updated, but we will add an option that this can be edited for a new version.
