If you think that you are being blocked...
The ONLY way you can get into SpamCannibal's database is by sending spam
or virus ladened email to our mail servers!
SpamCannibal does not block email access except for IP addresses and
ranges that have sent or relayed what we believe to be spam or other
unsolicited email directly to our email servers. SpamCannibal uses its
database to block access by IP addresses ONLY for its own mail servers,
however, the database we use for that purpose is freely available for
anyone to look at and use as they see fit.
If you have been referred to this site because you appear to be blocked
by some third party, speak to the administrators of the third party site
you are trying to contact.
SpamCannibal does not scan remote hosts or otherwise test remote sites.
The ONLY way you can get into SpamCannibal's database is by sending
unsolicited email to our servers!

welcome to the postfix mailing list! This list is about postfix.
- this list has no contact with spamcannibal
- this list has no contact with "yahoo and gmail and others"
- the fact that your "domain can be resolve able" is irrelevant.
- if you are using spamcannibal in your server and that blocks
legitimate senders, then stop using spamcannibal.
