Im unable to connect to: http://www.simsig.co.uk
through Tiscali, they are aware and have replied to my email - quote:
"This has been introduced as a spam fighting measure, it means that the sending server doesn't not have a reverse DNS entry, because of this our servers can not verify its source. If The sending server has a reverse DNS entry added then our servers will accept the email.
Question If I connect through a proxy server - http://www.connectionproxy.com
will this compromise my security!
