So I was able to ping the OS X server no trouble at all. But when I
tried telnet to port 25 it failed with that odd error. That looks
to be the root of my Network Stream error. Do you have any idea
where I might look to discover why OS X has clammed up like this?
If you are telnetting from OS X using the command line telnet (as it
appears you are doing), then you need to type "telnet 192.168.254.23
25". Notice it is space 25 not colon 25 as is used for most other
things when specifying the port.
I know postfix is running, because if I ssh into Outsider I can
send mail from the command line and it goes out. Or it did a couple
days ago, I haven't checked it today. I just did this out of
curiosity, after ssh'ing into Outsider:
Connected to localhost:25.
Escape character is '^]'.
Host/Domain name is invalid
Connection closed by foreign host.
[Outsider:~] colin%
Shouldn't postfix answer localhost:25 when I am on that machine?
(This could demonstrate a void in my understanding.)
You can't SSH to port 25 if you are running an SMTP server (postfix)
on that machine. SSH, although works like telnet, attempts to
negotiate an SSL connection on connect, which postfix won't work with
(at least not by default in OS X). That is likely why it is closing
your connection right away. It connects, but then SSH tries to start
the SSL connection, postfix doesn't know what it is doing, and drops
the connection.
Or, you can check out the SMTP Auth hacked version of Emailer on
my web site
I would LOVE to do this, instead of my hacked up arrangement (which
requires that I keep the OS X machine running all the time). What
do I do? Is it all built-in?
It is all built in. The only catches are: 1) it only work with the
LOGIN type of SMTP Auth. Probably not a problem, but worth noting. 2)
it uses the POP account's username and password for the SMTP Auth
connection. This can be problematic if you don't have a POP account
on the mail server.
What I would do is download it, configure it, see what happens, and
if it fails, then let me know the configuration you are trying to use
and I can tell you what you are doing wrong.
