Our Server IP has blacklisted due to send spam mail and we are unable to send mail to gmail.
There is attached a bounce mail.
1) How can we identify the spam mail sender? or from which log we can detect the bulk mail sender?
2) How can we protect against spam mail?
3) How can we delist our Server IP from blacklist?
We are now in great problem for the above issue.
Can you please suggest us to release the problem?
