[SOLVED] My server is blocked by Orange

Hello,

I get this message when I send email to friends hosted by orange.fr or wanadoo.fr.
How can I prevent this ?

Here is the message :

This is the mail system at host zentyal.sammut.fr.

Looks like your mailserver is blacklisted. Most probably due to spam. You should check your smtp logs for abusive use.

Could you help me more ? I don't find in /var/log/ some kinds of logs about smtp!

Christian,

Are you French ? be aware there is a French section in this forum, in case it helps 

As Robb explained, you are rejected by the recipient's MTA because your IP or domain is seen as spammer.
You will not get that much information from you log (well, perhaps it's a bit too late  ) but you can check it using too like mxtoolbox.com

You will notice that, indeed, s******t.fr is listed as spammer domain, at least from spamhaus 
If Orange is using mail filter based on spamhaus, then this is enough to block mail you send to them...

[Escorpiom]

Some providers report their IP blocks on forehand to blocklists like Spamhaus, you have to ask your provider if they are willing to remove your IP from that list.
After that it will work.

Cheers.

Like Escorpiom said, sometimes providers use this method to make own mailservers impossible. Other providers just block SMTP port (or do both)
If you have to use your server as smtp server, I'd look for smarthost settings and use those instead of running your own smtp server.

Thanks for your answers.

I'm effectively blacklisted by spamhaus (and only this one).
So to solve my problem, I've followed you recommandation and now I use the smtp relay of my provider.

Regards

PS: my english is so poor, you recognize I'm french ?

[christian]

no    but sammut.fr and Orange (even if this company also provides services in many different countries) were both telling me that you could be French
