Re: Emails never arrive -- MIDRANGE-L

The problem I've seen over the past 25+ years is people get email "working"
and they don't care if it's correct or not. If it works, move on to the
next project. Things change with email (reverse DNS, new
authentication requirements, and now with Office 365 the requirement to use
OAuth 2.0.. no more passwords, not even app passwords. I'm sure GMail is
next).

Then emails stops working, or only works for a few recipients, etc...
you're right, IBM's SMTP stuff is simplistic and bandaid over bandaid. And
setting it up is a cluster.

Most of these shops don't have email set up properly. Not by their own
fault. Partially, but also partially because the IBM SMTP system is so
cumbersome.

Yes, I sound like a broken records, but my MAILTOOL software was created to
get around this because I just got sick of dealing with SMTP on the IBM i.

I've been on this list for 30 years now and I will continue to offer what I
feel is the best solution for sending IBM i email.

It has command and ILE interfaces... works with any mail router, even OAuth
2.0 which IBM has said they will not implement. Very easy setup, lots of
documentation, FAQs, easy debugging and great support from yours truly. If
you have a question or issue, I guarantee I've seen it at least 100 times
before.

From around $1400 a year to $2000 a year per partition depending on your

requirements (and discounts for dev, test, HA/DR, etc). That's less than
most spend on coffee. Way less actually.

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.

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
