After restart of my EC2 Host (CentOS ISPConfig 3) I found sendmail was only listening on localhost:25 ... I couldn't send mail until I restarted sendmail... I now can send via TLS, but standard SMTP was not working. I edited DAEMON_OPTIONS in sendmail.mc and restarted sendmail and it now listens on 25, but in the log I'm still seeing the message: did not issue MAIL/EXPN/VRFY/ETRN during connection to Daemon0 I'm also seeing some Relaying denied messages for incoming mail. Any ideas? p.s. incidentally my EC2 host went zombie after failing to lease a DHCP address.
Are you sure that you mean sendmail? ISPConfig 3 supports only postfix, it can not work with sendmail. In the perfect setup for centos 5.5, sendmail gets disabled and postfix is installed. You should read the mails etup part aain and ensure that you issued all commands as decsribed there.
DOH! yes stopping sendmail and starting postfix worked fine. Was me in a panic'd state. I'll have to look at my autostart config because I had quite a few issues today after server restart. Thanks for setting me straight.
