This is with port 25.

If I change it to port465 I get this.

The last email I received was on 05/26/2016 at 8:55 AM. Nothing has come through since that time.
This the name servers being used;

Code:

75.75.75.74
208.67.222.222
8.8.8.8.

This is the release;

Code:

FreeNAS-9.10-STABLE-201605240427 (64fcd8e)
Intel(R) Core(TM) i3-4370 CPU @ 3.80GHz
16291MB

I have tried using TLS, SSL, and Plain without any success. The user root has the correct email address and the password is set correctly. I need SMTP authentication set as Comcast requires it.

Does anybody have any ideas?

Thanks!

What happens if you telnet to the mail server?

Code:

telnet name.of.server 25

 

[Crotalus]

Here it is! I tried it from two different systems to the outgoing mail server.

Code:

[root@freenas] /# telnet smtp.comcast.net 25

telnet: connect to address 96.114.157.81: Operation timed out

And if I try;

Code:

[root@freenas] /# telnet smtp.g.comcast.net 25

I also tried to use smtp.g.net in the FreeNAS set up with the same results as before.
My Thunderbird setup is using port 465, and it works. Requires a password to access the Comcast server.

 

[Sakuru]

Interesting. It looks like you are no longer able to access port 25. It works for me and I'm not on Comcast :) Call them and ask them if they blocked that on purpose.
It looks like the "No route to host" message is from it trying to use IPv6.
You could also trying using 465 and filling in your credentials.

 

[dlavigne]

To add to this comment, FreeBSD 10 defaults to preferring IPv6 if it is available (as in ignoring IPv4). I discovered this on my FreeBSD-based systems as my provider automatically assigns an IPv6 address but no other IPv6 info. To tell a FreeNAS system not to do this, create a Tunable as follows and reboot the system:

Variable: ipv6_activate_all_interfaces

Value: NO

Type: rc.conf

We've also discovered that FreeBSD 11 doesn't honor that variable (something else overwrites it) and are currently troubleshooting that.

 

[Crotalus]

Comcast does not use port 25. They require port 465 for security reasons. They did this several years ago and I remember now that My emails quit and I was told to change the port. I have to use port 465 and set to SSL/TLS and use a password to access my emails using Thunderbird on my Windows 7 system.

When I set the FreeNAS to SSL I get

Your test email could not be sent: (550, '5.1.0 size=328 invalid address', u'freenas.local')

When I use TLS in FreeNAS I get

Your test email could not be sent: Connection unexpectedly closed: timed out

It has to be something in FreeNAS. I will give the above post a try and see what happens.

• Your test email could not be sent: (550, '5.1.0 size=328 invalid address', u'freenas.local')

 

[Crotalus]

I add the tuneable to the system, rebooted and tried the email. Result;

Code:
