Privatisated in 1996, the Laboratory of the Government Chemist has been aiding spammers by relaying mail from it's badly configured mail servers for a number of months now. That os to say they've been relaying spam to me and I'm bloody sick of it.
Basically spammers have exploited a flaw in LGC's configuration whereby they send a mail to a non-existant @lgc.co.uk email address but put the spam's target address (mine) in the RETURN-PATH header. The result is that the target receives a spam email which appears to be a bounce from a mail server. Thus giving the impression it orignated from the target.
Sadly, LGC are incompetent and no matter how many times I tell them about this they do nothing. Time to get their mail server blacklisted, if they stop getting mail it might jolt them into action. No more Mr Nice Sysadmin.
