we are using exchange server 2007, and only sometimes we receives error msg Relaying denied. IP name possibly forged [*.*.*.180] ##
while sending email out to some id's.
we have leased line supplied by entanet and got dedicated ips, we are using cisco router with allow all traffic as main gateway then draytek vigor router to do all port redirection stuff,
[*.*.*.180] this is our main network ip and thats also our mx records for domain. mail.claim-today.com .
