The mailing list for listmasters using Sympa

["Roger B.A. Klorese" <address@concealed>]

One of our uses uses McAfee SaaS (formerly MXlogic) for 
anti-spam/anti-malware processing of their email.

One of the things it does is attempt to identify phishing and other 
linked malware by following the links.

Unfortunately, this seems to be incompatible with the ticket system, 
since once the mail is checked and delivered to the user, the ticket 
link is already invalid...

Any suggestions? This is a pretty common anti-spam/anti-malware approach.
