I am working on ec2 ubuntu 12.04 hvm client. I have setup an MTA i-e Exim and IMAP/POP Server i-e dovecot and a webmail client afterlogic. IMAP server is working well but SMTP gives error. While sending email afterlogic fails. I have checked logs and got connection fails connecting to 127.0.0.1:25. In Exim configuration file I have uncommented the line which gives list of ports including 25:487:etc Any help would be appreciated.
I got the solution to this !!! Open /usr/exim/configure in your favorite editor and change the following lines:
In MAIN CONFIGURATION section change local_interfaces = <;127.0.0.1; to local_interfaces = <; your-ec2-privateIP ; change sender_unqualified_hosts = localhost to sender_unqualified_hosts = your-ec2-privateIP change recipient_unqualified_hosts = localhost to recipient_unqualified_hosts = your-ec2-privateIP
restart exim and port 25 smtp will be open and you will be able to send email
