There is a reason to MAYBE not use this.
Is imscp using mod_ssl SNI?
Because some retarded soft like IE will throw an error on certs EVEN if doc/feature says it respect SNI EVEN on latest version, etc.
Seen that many times in win7 (supposed to be only XP)
These 
soft will only trust the 1st cert on the list
and I can't trust these soft... obviously!
If Lets say there is one cert that I really need to have in 1st place and it is not the imscp hosting domain.
Isn't this a manually accpetable case ?
