Adding SMTP port 587

[prasad]

To get exim to listen on both port 25 and port 587, you'd add the following code to the very top of the /etc/exim.conf file:

vi /etc/exim.conf

daemon_smtp_ports = 25 : 587

Once saved, restart exim:

/sbin/service exim restart

But since port 587 is to be used only for authenticated users, you’ll also need to make few more changes:

Here is the step by step information :

#vi /etc/exim.conf

Search for the line “ system_filter = /etc/system_filter.exim ”
add the following underneath it,

daemon_smtp_ports = 25 : 587

But since port 587 is to be used only for authenticated users, you’ll also need to make this change; the following code needs to be put under the first ruleset under the “check_recipient:” section:

# to restrict port 587 to authenticated users only
# see also daemon_smtp_ports above
accept hosts = +auth_relay_hosts
condition = ${if eq {$interface_port}{587} {yes}{no}}
endpass
message = relay not permitted, authentication required
authenticated = *

Open port 587 in firewall

restart firewall

restart exim

You can verify it using telnet to port 25 and 587
