mailing lists mail delivery problems

[Christian Costa]

Hi,

This is about one month or so I'm experiencing problems with mailing lists.
Indeed, mail delivery is disabled randomly for some of them.
I have to turned on again the delivery by editing options of my account.
This is really annoying.
Is anyone experiencing the same kind of problems?
What's happening? How can this be solved?

Thanks in advance for any clue.

Bye,
Christian
