Guys, sorry for another "I'm having trouble with mail thread", but I am.  :'(

 

I recently switch from Verizon DSL to Comcast cable.  I'm trying to configure SMTP on my unRAID box.  I've tried all kinds of combos, but everything I try results in this:

 

root@Tower:/usr/local/etc/ssmtp# echo -e "Subject: unRAID\n\n Test from EJH." | ssmtp -d root

ssmtp: Cannot open smtp.comcast.net:25

 

Any ideas?  Does that message mean it can't find the outgoing mail server or that it can't use it?

 

I use Outlook on my WinXP machine to read my mail and it's set up to use port 25.

Do you have your IP set manually in the unraid settings? If yes, did you make sure to add DNS servers?

I think you're on to something.  I have my tower set to have a static IP.  Here's my config:

 

root@Tower:~# cat /boot/config/network.cfg

# Generated settings:

USE_DHCP=no

IPADDR=192.168.2.100

NETMASK=255.255.255.0

GATEWAY=192.168.2.1

DHCP_KEEPRESOLV=no

DNS_SERVER1=192.168.1.1

DNS_SERVER2=

DNS_SERVER3=

 

I got a new router a few months back.  When I look at the settings in the router, it's gets it's DNS Address "Get Automatically From ISP".  The address there is not a local IP like I'm used to seeing.

 

The router shows the current DNS IP it's using.  A quick google check shows them to be Comcast's DN servers.  I think I'll update my network.cfg and try again.

 

I'm doing a preclear now though, so I can't reboot.  Is a reboot required for changes to network.cfg to be picked up?

 

Thanks for the help mrow.  My DNS IP was wrong and that was the problem.  I looked at my router for the DNS IP it was using and put that into the unRAID Network settings.  After updating (with no reboot), I'm sending mail again.

I typically find you're typically better of just making a DHCP reservation on the router end, then you avoid little problems like this.
