[Linux-aus] PSA: Messages sent through LA mailing lists being classified as SPAM

Hi Folks

I just had to re-enable my subscription to linux-aus as the Mailman 
instance had disabled my email subscription due to excessive bounces.

I use the anti-spam services offered by SMX (smxemail.com) and using 
their Web UI I can see that the emails identified by the attached CSV 
were recently rejected as spam by their platform.

Their spam engines are commercial in nature and whilst pretty accurate, 
do false-positive occasionally. It suggests that something about the 
email content/payload matches an email previously reported as spam to 
one of the engines concerned.

If one of the list administrators is able to capture one or more of the 
emails that was bounced, it can be sent to emailsupport at smxemail.com 
with the comment 'false positive' and they can re-check it and if still 
reporting as spam, attempt to correct this.  Otherwise a warning for 
anyone else employing anti-spam software.

(I've now whitelisted the envelope-sender for both linux-aus and 
announce lists... but from my view I will never see the offending 
messages as they were 550 rejected by my MX's).
