Information Systems:M-Daemon Mail Server

Problems

Locked Accounts

MDaemon may automatically accounts based on certain activity patterns. One such rule is the attempt SMTP sending of 250 outbound messages in 30 minutes. This indicates a hijacked account, and requires that the password be changed for the account. Following, this any active SMTP sessions (likely many if this is a botnet hijack) need to be terminated, and this is best done by restarting the SMTP server component of MDaemon.
