Re: Using SNDSMTPEMM command...

Hi, Brad,

Thanks for your response.

I'm confident your second option is what is happening because we have no intermediate email server. So, no exchange server, Office 365, etc.
I've looked at the article you suggested and got lost when I tried to follow the links that said 'read this article'. They lead to another page with lots of stuff, not really an article (or I'm too dense to grasp it).

I think the operative message in your base link is this...

*If you are using the base MAILTOOL product, the Send Distribution (SNDDST) command, the Send SMTP Email (SNDSMTPEMM) command or another 3rd party email client*, the email server should be listed in the CHGSMTPA command under the Mail Router Parameter (and, if you're on V6R1 or higher also on the Forwarding Mail Hub Server Parameter).  The Firewall parameter should also be set to *YES. /If this isn't the case, or your Mail Router parameter is *NONE or blank, you're not using a mail router and have bigger issues/.  You almost always should be using some sort of mail router or SMTP/outgoing mail server to deliver mail.  Rarely will you be directly sending mail from your IBM i.

Clearly we are not using a mail router (and have bigger issues).

What's weird is that this all used to work for years. The only thing that's changed is a router replacement back in summer 2020. Would that have an impact? Could it be setup incorrectly somehow?

Forgive the obvious ignorance in my questions.

Best Regards,

Thomas Garvey

My best is it's not set up properly. Yes, I have heard from many that
think it is, but these days with cloud based email, the IBM SMTP server is
quite a chore to set up properly, if you can get it working at all with
authentication and TLS/SSL.

But normally when it goes to some, and not others, it's because you have it
set up incorrectly and you're delivering email directly from your IBM i to
the recipient (ie, you're skipping the mail router because of the setup).
So, some email recipient's servers will take it, and others won't.. mainly
because they can't do a reverse DNS lookup on the IP being reported by your
system.

So in a nutshell, email should go:

IBMi ---> Mail router (in house exchange server, Gmail, Office 365, etc)
---> recipient

Yours is most likely going:

IBMi ----> recipient

Which is incorrect. While I don't really work with the IBM SMTP server
anymore, I do offer solutions to make things a LOT easier to set up and
configure, and even offer the tools to use for free for debugging.

Here's an article with much more information:

What settings would keep emails from being sent to specific email
addresses?
It works to my business address but not to my personal email account.
