Sorry for off-topic, but Fabio, are you aware that your email address is in a spam blacklist? Hello

I wasn't aware at all about the blacklist from lashback. Unfortunately my mailboxes are hosted in a shared host, most probably some users from that host has made spam so lashback has listed the source IP as spam source.

All my email addresses are really old and I wouldn't want change them so I'll try to fix the source of the problem with the maintainer.

If you have useful suggests to solve the trouble please let me know in some way.

I've dealt with this kind of issue in the past and the first two measures that you can implement are a) SPF records and b) DKIM signing. All is published in TXT DNS records. The only downside of DKIM is that there are signing facilities for sendmail and postfix only AFAIK and you seem to prefer exim4. After you have these measures in place it will be much easier to have your domain cleared up. Even if the IP address is shared, the SPF records are exclusive to the context of your domain.
