Hi,

It seems Orange is currently being blacklisted, true that 
http://www.spamhaus.org/query/bl?ip=41.202.225.153


What you can do is have a hosting package somewhere that supports port 587, 
which is authenticated SMTP. Then forward your email over port 587, past the 
Orange SMTP services into that host outside their network.

If you want to lower the chances of having your email marked as spam, 
implement http://www.dkim.org/ along the way.

Then prey to the Internet deities.

rgds,
reinier

What if my ISP's IP is black listed? I use blacklists on my mail server 
(http://www.spamhaus.org/zen/)


The failure delivery reports clearly state my ISP's address as being listed 
and indeed when I check on the blacklist, voila it's there. I have engaged my 
ISP on this issue but they seem reluctant to clean it up. However much they 
try delisting, it only takes a few seconds for the IP to appear again

Hi, 


Try running wireshark  or any other such tool on a machine on your LAN and 
monitor traffic on your network for a while. Lookout for outgoing SMTP mail 
traffic from any other host that is not your mail server. If you find any host 
sending out mail on port 25, that is likely to be the culprit, deal with it, 
then request to be de-listed from the blacklist.


Regards
