Hi,
I would like to limit the number of valid logins per minute to the SMTP server and log this value per user.
I would like to get such an effect that after exceeding e.g. 10 logins per minute, the user on the next attempt will get a message about the exceeded number of logins and the need to wait.
I also need to detect valid logins from different IP addresses from the last hour - I need this to detect hijacked account login credentials that have been used to send SPAM - e.g. via a botnet.
Thank you in advance for your reply.
Matthias.
Limiting correct SMTP logins
Discuss your pilot or production implementation with other Zimbra admins or our engineers.
