• Hey guys, im not able to send emails to an existing email Id's and frequently getting an auto generated report saying " This is permanent error" (Message sent failure, ip address does not exist, check the ip address - even ip address is correct its not delivered) were i not able to send any mails, Msgs.... Please let me know the solutions...

• Answer:

  Yes the email address probably still exist. When Email boxes get Full they can neither send or receive. Some IP addresses get blocked due to Spam even if they didn`t send it. Mainly they can`t shut off one IP. They have to shut off a section of them. Sometimes it takes 30 days of the bandwith to not send Spam before they put them back online.
