Hi all, I finally sorted out what's the problem with the mailing lists. The lists are hosted on the unipi.it premises. This university has been attacked regularly by many sites. For this reason the mail administrators have added some checks. In particular: 1. rbl.maps.vix.com 2. rbl-plus.mail-abuse.org 3. a list of sites from which unipi is receiving attacks (not spamming).
In the case of 3., before adding a site to the list, the unipi mail administrator sends 3 times a mail to the domain postmaster to ask stopping the attack. If no reply is received, the domain is added to the local black list. In this case you will receive a mail that contains something like: ==== Connected to 131.114.21.25 but sender was rejected. Remote host said: 550 5.0.0 You are not allowed sending mail to our site:stop bombing SoB!! ==== If this is the case I cannot do much. What you can do is to ask you postmaster to mail [EMAIL PROTECTED] or [EMAIL PROTECTED] asking to be removed from such a list as there are no known attacks in progress. Otherwise you can send emails using "safe" domains.
