Hi dear,
I'm very interested in your project.
I'm experienced in Linux/Unix systems administration. I've installed & configured various services under Linux/Unix till now, including ejabberd XMPP service.
So, I'm ready to investigate and solve your problem as soon as possible.
note: while I'll try to solve your problem in 2 hours or less, but it may takes longer depending on the type and root of the problem.
waiting for your answer
best regards
