Halo Matt,

First of all, I want to thank you for the solution provided and for the explanation.

I try to follow your instruction by adding said <smtpserver> tag and change the <bind>, and <tlsSocket> to true (I copy paste the info from my port 25 SMTP and didn’t include the jmxname because it can be ignored):

<smtpserver enabled="true">
        <bind>0.0.0.0:465</bind>

        <tls socketTLS="true" startTLS="false">
           <keystore>file://conf/keystore</keystore>
           <secret>pass</secret>
           <provider>org.bouncycastle.jce.provider.BouncyCastleProvider</provider>
           <algorithm>SunX509</algorithm>
        </tls>

        <connectiontimeout>360</connectiontimeout>
        <!-- Set the maximum simultaneous incoming connections for this service -->
        <connectionLimit>0</connectionLimit>
        <!-- Set the maximum simultaneous incoming connections per IP for this service -->
        <connectionLimitPerIP>0</connectionLimitPerIP>

        <authRequired>true</authRequired>

        <authorizedAddresses>127.0.0.0/8</authorizedAddresses>
        <maxmessagesize>0</maxmessagesize>
        <addressBracketsEnforcement>true</addressBracketsEnforcement>

        <handlerchain>
          <handler class="org.apache.james.smtpserver.fastfail.ValidRcptHandler"/>
          <handler class="org.apache.james.smtpserver.CoreCmdHandlerLoader"/>
        </handlerchain>

</smtpserver>

And I try to get my mail server from thunderbird (also changed the setting to port 465 SSL/TLS), but the connection got refused and I cant even send email. I try putting the SMTP port 465 code under the SMTP port 25, so maybe the SMTP port 25 get loaded first before the 465, but still no luck.

Is there something im doing wrong or I miss or I need to look out?

Sincerely, Jason
Sorry for any wrong word, and thank you for the help

Hello Jason,

if I remeber correctly from an older topic, it's possible to use more 
than one port per service. In <james>/conf/smtpserver.xml you normal 
have this layout:

<smtpservers>
    <smtpserver>
        <bind>0.0.0.0:25</bind>
    </smtpserver>
</smtpservers>

This is the required one on TCP/25 for receiving e-mails from the 
outside world. Why? SMTP uses TCP/25 for inter-server communication: 
each MTA that want to talk to another MTA has to do this on TCP/25 - if 
TCP/25 isn't open or there is no SMTP server on this port mails can't be 
delievered.

If you want additional ports for TCP/465 (socketTLS) or TCP/587 
(startTLS) you just have to add another <smtpserver>-block. You can just 
copy the existing block. But you have to change the jmxName, or delete 
it, as there can't multiple jmx entries with the same name.

So you can do this:

<smtpservers>
    <smtpserver>
        <bind>0.0.0.0:25</bind>
        <tls socketTLS="false" startTLS="true">
            <!-- stuff -->
        </tls>
    </smtpserver>
    <smtpserver>
        <bind>0.0.0.0:465</bind>
        <tls socketTLS="true" startTLS="false">
            <!-- stuff -->
        </tls>
    </smtpserver>
    <smtpserver>
        <bind>0.0.0.0:587</bind>
        <tls socketTLS="false" startTLS="true">
            <!-- stuff -->
        </tls>
    </smtpserver>
</smtpservers>

This way you open your james on ports 25, 465 and 587. The startTLS on 
25 is so other MTA can drop mails over encrypted channel, but you can 
set it to false. Make sure to set authRequired to announce to enforce 
SMTP AUTH or set authroizedAddress correctly (also check 
mailetcontainer.xml !).

About TCP/25 is marked as spam - I guess you're either in a larger 
network or use an ISP with strict policies, as it shouldn't be blocked 
allthough it's a good anti-spam mechanic. Try contact the admin/support 
about policies about TCP/25.
