Re: Emails never arrive -- MIDRANGE-L

Friends, this is happening all over, not just IBM i, but also IBM Z.

SNDSMTPEMM is simplistic, and the requirements of industrial-strength SMTP relays are becoming increasingly stringent.

The bottom line (at the moment) is that you can either figure all this out, fix various configuration factors in SNDSMTPEMM, possibly find a new SMTP relay (in house?) that can feed Comcast / Microsoft Exchange / Gmail etc. what it eats, possibly write an SMTP sending program in PHP or Python, keep up with changing rules promulgated by the major relayers.

Or you can stop sending email directly from the legacy server (IBM i, IBM Z).

Seiden Group (with whom I also consult) consults on this and has been stop-gapping for various organizations in this problem domain.

Follow-up to emails never arriving...
I figured out how to turn on a trace to SMTP. And doing so has somehow now allowed using the SNDSMTPEMM to WORK, but only for one of the email addresses I've tried.
It will send to my unpath.com address but not to my personal accounts at comcast.net.

I've tried the SPAMHAUS site and none of my IP addresses have issues.

What are you using for email? If its Office 365 they don't allow user/password authentication anymore

<vendor>
We have had a plugin for O365 and Auth 2.0 for a few years now. MAILTOOL is the base product and G4MS (GreenTools for Microsoft) has a plugin that allows you to set up OAuth 2.0 and have all the token processing be transparent in the background.

Here's an article:

I apologize for bringing this up again.

I'm using SMTPSendMail (on OS v5) and the SNDSMTPEMM command (on OS
v7) to send emails with attachments from within a RPGLE program.

Reviewing the joblog indicates the emails are sent successfully (email
server engages and responds with expected messages). But emails never
arrive. This used to work a few years ago.
I've tried sending to several different domains, including personal,
business, and gmail accounts.

I've also tried this on servers that are not mine. No emails arrive.

Can someone point me in a direction to figure out why? Where else can
I look?

Kind Regards,

Thomas Garvey
