[Users] too many bouces information message..

[Gianluca Cecchi]

Already received some weeks ago this kind of message I just received today:

"
Your membership in the mailing list Users has been disabled due to
excessive bounces The last bounce received from you was dated
08-Jan-2014.  You will not get any more messages from this list until
you re-enable your membership.  You will receive 3 more reminders like
this before your membership in the list is deleted.

To re-enable your membership, you can simply respond to this message
..
"

At the mean time I just re-enabled my membership receiving confirmation message.
What could be the reason? I'm only normally using via web my gmail
account that I use for other mailing lists too, without any
problem....
A difference is that I statistically find more messages from the list
that gmails initally puts into spam and that I mark as "not spam"....

Any hint here?

Thanks,
Gianluca
