I've be asked to create a news thread to share the FAQ I have just published...

Here: faq940-7890

I hope others find this useful when troubleshooting vm to email issues.
 
Although relatively easy to find instructions on testing SMTP via telnet placing it here as an FAQ is probably long overdue

Sometimes you need to test this from the application server or the C110 directly, e.g. when the SMTP server only accepts mails from that ip address or when a firewall is in play.
Unfortunately Telnet isn't installed by default.
Though, you can install it manually.

First we need to find the [highlight #FCE94F]Linux version[/highlight] and [highlight #729FCF]architecture[/highlight].
Code:
[root@uc-module ~]# uname -r -v -p
3.11.4-1.appscard.[highlight #FCE94F]el6[/highlight].[highlight #729FCF]i686[/highlight] #1 SMP PREEMPT Wed Mar 4 17:38:10 EET 2015 i686

Go to RPM resource telnet to find the correct [highlight #FCAF3E]link[/highlight].

Code:
[root@uc-module ~]# cd /tmp
[root@uc-module tmp]# wget [highlight #FCAF3E]ftp://rpmfind.net/linux/centos/6.7/os/i386/Packages/telnet-0.17-48.el6.i686.rpm[/highlight]

That may result in problems (it shouldn't)
& Avaya would use it as an excuse to reject support

you could also look into SSH local & remote port forwarding which should enable you to telnet from your own pc THROUGH the server concerned to get around the ip address restriction, I have not had time to test this yet.

it is amazing what features he SSH protocl offers when you look into it, not just a simple remote shell.
