RE: Delayed email (sent through QtmmSendMail, either directly or via MMail)

I have used a technique similar to this
https://www.wikihow.com/Send-Email-Using-Telnet
for some testing.
Replacing the DOS telnet command with
TELNET RMTSYS(MAIL.DOMAIN.COM) PORT(25)
You may have to use a service like
http://www.zmailer.org/mxverify-cgi.html
to figure out a MX server to use in the RMTSYS() parameter.
Kind of funny to see that service use those same telnet commands, and show them to you, as part of their test.
Just don't expect to use backspace to correct any typos. You'll probably have to start over. Or RSET.

Just to add further to what Brad has said.

The other problem of sending the emails directly is that increasingly recipients are demanding higher verification levels through the DNS entries among other things.

The switch to managed servers such as gmail and Office365 has exacerbated this and emails that used to reach an address will often fail to do so after the recipient switches to (say) a gmail hosted server. We gave up trying in the end - meeting the ever changing requirements was costing more than the monthly cost of a gmail server and using that for all outbound traffic. A few $s a month and all my problem emails disappeared. Or rather they didn't disappear - they actually got to the recipient in a meaningful timeframe!

Some other thoughts:
If I have

Mail router . . . . . . . . . . *NONE

then where does the outgoing email go, directly out of our box? Our
ISP's SMTP server? Someplace I don't know about?

Directly to the recipient's mail server.

Normal: IBM i ----> Email Server/Router ---> recipient (good)

You: IBM i ----> recipient (bad)

Normally email will go from your box to your mail router. In the old
days that was an Exchange server. A lot these days use a cloud
service like Office 365 or GMail.

Once at the mail router/service, then the mail is delivered to the
recipient.

Exchange servers were easy to get email working with. There as
normally no authentication or encryption (ssl/tls).

Office 365 and Gmail and other cloud servers require authentication
and encryption.

Why use a mail router? So email is funneled through one server to every
possible recipient you want to send to. Any PC, Mac, tablet, Phone, and
even your IBM i should funnel email through that mail router. That
mail router is normally set up so it's trusted by end recipients using
reverse DNS and other means. Things we don't want to have to worry about.

Its just like giving your mail to the mail man, and then having them
deliver it, vs you putting every piece of mail directly in the
recipients mail box/PO box.

I deal with this many times a week with customer. "It's always worked
before" is the one answer I get from all of them. Why? Because
before it wasn't a big deal. Now with the cloud services things are a lot different.

MAILTOOL has worked with cloud servers for over 15 years. Since I
needed it with GMail back then.

You have a couple options...

1. Call IBM and ask them to help you set it up.
2. Use a 3rd party product, like MAILTOOL, and be done with it.

#2 shouldn't take more than 30 minutes to get set up and installed and
working. Very cheap too.

I put that article together as a FAQ for my customers and others with
questions on how to set things up so things will work as expected.
