Email blocked when I email a person - but Ive test emailed gmail etc

I sent an email to a customer and got this bounced back to me ..........
Do I really have to give loads of details to be unlisted?

SMTP error from remote mail server after RCPT TO:<abc@yyy.ie>:
host clustera.tstechnology.net [91.199.74.13]:
554 5.7.1 Service unavailable; Sender address [info@xxx.ie] blocked using multi.surbl.org; Blocked, xxx.ie on lists [ph], See:

If you are on a blacklist, the only way to get off it is by having that list take you off it. Some are free and you can unlist over the web, some charge and require more info.

Papertrip

Of course, if you haven't fixed the reason of why you were blacklisted in the first place, the chances of getting re-listed are pretty high.

Agree with Papertrip. You should try to find out why you're on the blacklist, as well as get removed from it.

How am I supposed to find out why its listed?

Papertrip

Have to talk to the people who manage the blacklist. Some blacklists will say why you were listed, some will not. There is no standards at all for blacklists.

As you can see now, blacklists suck. Don't get blacklisted again :p

IT-Monkey-Dave

surbl.org should be willing to tell how/you why you made their list.

The only thing is can think of is I had passview.exe (considered a hack tool for revealing outlook passwords)
on the site. I had it there handy for myself to download when needed. It wasnt being used for spam etc.

Could that be the spanner?

Papertrip

Any malicious software installed on any machine that is able to send mail through your server could be the source of the spam.

Put your mail server in at http://www.mxtoolbox.com/diagnostic.aspx and make sure you are not an open relay.

Papertrip

You should always firewall access from internal machines to internet on ports 25 and 465, except for your mail server. Force all internal clients to use that mail server. That way, amongst several other advantages, you will have logs to reference to spot any suspicious mail traffic on your network.

Papertrip: > So whats the flupin problem? It is a shared server.

Will I just request to be unlisted?

Will I cal my ISP tomorrow and ask them to run a check first?
