The email sender or Email Service Provider may visit http://www.verizon.net/whitelist and request removal of the block. 130729) [email protected] It is quite strange as mail-domain for web10 is not created at all. Need a solution ASAP. can't find a way to block this mails. These spam will soon blacklist my IP
It seems that your web with id 10 sends spam through php mail function. These mails have sender web10@servername (user web10 is the web user that runs php). You could either block this whole web until the owner has checked what script sends those mails (or maybe the web was hacked!). Or you could globally disable the php mail function in the php.ini of the server.
