I just sent Michael a long email regarding JNOS stations trying to send email directly to commercial MTA mailservers.<BR>
<BR>
I'll try to summarize here:<BR>
<BR>
It's a coin toss if JNOS can successfully *send* email directly to a commercial email server. JNOS does not use industry standards for authentication when connecting to a mail server. <BR>
<BR>
JNOS still uses standards that existed way back when the internet was first getting going.<BR>
<BR>
Authentication standards have changed, mainly to prevent spammers. Since the JNOS smtp server has never been upgraded to authenticate using today RFP standards, some commercial email servers will reject a JNOS connection.<BR>
<BR>
Something important to know here is that not all JNOS stations *RECEIVE EMAIL DIRECTLY* !!<BR>
If your JNOS smtp server calls another JNOS station direct, and the JNOS on the other side answers, it should transfer mail fine.<BR>
<BR>
However !!!! If the JNOS station on the other side is configured to use SOMEONE else's mail server hosting services first, your JNOS is actually connecting to an MTA station and not a JNOS station. The hosting MTA server may reject your JNOS's connection for failure to authenticate with today's standards.<BR>
<BR>
So, not all JNOS mail server configurations are equal !!!<BR>
<BR>
Beware that using your JNOS to send email DIRECTLY to someone on commercial internet may have a high failure rate.<BR>
