Sendmail issues after EC2 Hosted server restart
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.
p.s. incidentally my EC2 host went zombie after failing to lease a DHCP address.
