There are at least three different but very similar locations for setting up mail auto-replies in Usermin:
1) "Automatic Reply" in the "Mail" sidebar menu. 2) "Mail Forwarding and Replies" in the "Usermin" sidebar menu, under the "Mail" sub-category. 3) "Email Filters" in the "Mail" sidebar menu, which is the same as "Filter and Forward Mail" in the "Usermin" sidebar menu, under the "Mail" sub-category. The "Automatic Reply" (#1 above) is the a subset of this filter module.
Both of these screens have fairly simple options to set up auto-replies, however they are inconsistent, which causes confusion. For example, if the user goes into the forward module and selects the option to send an automatic reply, enters a message, and configures a minimum time between replies, none of these options are propagated to the Automatic Reply module, even though they have almost the exact same counterparts. If the user later goes into the Automatic Reply (filter) module, it appears that auto-replies are turned off, even though they are still configured in the forward module.
I haven't tested further to see what happens if they are both configured separately (i.e. conflicts) or other issues that might arise from this redundancy.
Can this be made more consistent, or can one of these modules be removed to prevent confusion?
