For one thing none of your IP seem to have "reverse" DNS.

mail.arthur-lerner.com relates to 208.144.236.201, but
208.144.236.201 does not... (and neither does 208.144.236.130).

I just sent a test email to the address in your message 
(elmert@xxxxxxxxxxxxxxxxx) and it was at least delivered to IP 
208.144.236.201.  Be interested to see if you actually get it.
