Sendmail Rate Limit [SOLVED]

[latifolia]

Hello,

Can I have information where we can set limit (loosening or tightening) the rate of email sending? Like maybe from 4 mail/sec to 1 mail/sec for users?

Hallo,

you can install policyd-rate-limit

apt install policyd-rate-limit

http://manpages.ubuntu.com/manpages/foc ... mit.8.html

Or try it with:

smtpd_client_message_rate_limit

Thank you!

I set this on /etc/postfix/main.cf

Code: Select all

# Prevent SPAM from bcc
smtpd_recipient_limit = 3
smtpd_recipient_overshoot_limit = 3

# Rate-limit mail sending to prevent ABUSE & SPAM (3 mails/60s)
smtpd_client_message_rate_limit = 3
anvil_rate_time_unit = 60s

I can now sleep well knowing my server will not bow to any spammers whenever they hacked into my user mail accounts.
