Re: How to manage my iredmail about spam mail ?

Usually this issue is caused by someone cracked mail account password and use it to send spam. So here's general suggestions:

*) Ask all your users to reset password to a STRONG password.
*) Make sure you have 'reject_sender_login_mismatch' in Postfix config file /etc/postfix/main.cf, parameter 'smtpd_sender_restrictions'.

Also, if you have iRedAdmin-Pro installed, one addition suggestion:

*) Quarantining detected SPAM/Virus into SQL database for further approval. Reference: http://www.iredmail.org/docs/quarantining.html

Check mail log file (/var/log/maillog on RHEL/CentOS) to find out who sent spams.
