Seems like the servers are blacklisted:
Your IP address is DNSBL listed as a SPAM source - check this at
http://www.dnsbl.us.sorbs.net/lookup.shtml?220.127.116.11 - Get your ISP to
fix if error. (in reply to end of DATA command)
I already logged it with IS.

One of my clients got exactly the same thing yesterday.
Although I think that it is the client's IP address that is on the blacklist, NOT smtp.isdsl.net !!!!
So, get the user a new IP addy, and the problem should be fixed!!!
I thought that IS should whitelist their entire IP addy range and so they ALWAYS accept mail from their own users... even though someone might be blacklisted on a SPAM list...

If you look at the Information section of the report, it is not IS's Server address but other addresse in the /24 range and so they (sorbs) block the whole subnet.
Netblock: 18.104.22.168/24 (22.214.171.124-126.96.36.199)

Additional Information: Escalation listing, multiple spammers hosted with the /24. 188.8.131.52/173/190.

I have the same issue with my ISP's private smtp server. I had to revert to using smtp.saix.net.
I have the same issue with my ISP's private smtp server.Do you use SMTP AUTH when connecting to that server?

Do you use SMTP AUTH when connecting to that server?
It used to work at one stage, I can't remember whether it required a username and pwd though.
