Hi all,

Hope someone can help, I have implemented security on my mailserver in the form of ACL's. The following lists are used:

dnslists = relays.ordb.org
sbl-xbl.spamhaus.org
hil.habeas.com
list.dsbl.org
bl.spamcop.net
dnsbl.njabl.org
proxies.blackholes.easynet.nl
dynablock.easynet.nl
spam.dnsbl.sorbs.net
korea.services.net
brazil.blackholes.us
nigeria.blackholes.us
argentina.blackholes.us
malaysia.blackholes.us
singapore.blackholes.us
taiwan.blackholes.us

and it is working great, it is blocking almost 99.9% spam, it is blocking the odd wanted mails but I can live with that. Once thing that is still happening is someone is sending out mail using our domain name Funksta.net and adding anything before the @ sign as I am getting rejected mail from other sites, here is one below:

How can I stop this. It is the only domain it is happening to and I think it is because this domain used to be hosted on a reseller account on the very insecure Interservers.

Any help would be great.
