[Obm] Can one use Exim instead of Postfix?

[Jan M. Dziewulski]

Hello,

I am currently interested in using Exim instead of Postfix as it is 
running on my server. I also have all the config set up nicely through 
Apache as I like it. Is it possible for me to coerce OBM into using my 
current setup with a) Exim and b) Apache set up as *I* want it set up or 
do I have to bow down to how it has been set up by the dev team?

Thanks,

Janek
