Re: IBM i as email relay -- MIDRANGE-L

MAILTOOL and MAILTOOL Plus or the email Addon for GMail.

With MAILTOOL and MAILTOOL Plus you can use app passwords generated by
Google.

If you have an application that already creates a MIME file you can choose
the G4G send email addon which uses OAuth 2.0 you already have everything
else you need (G4G base, GETURI) and you can write the email sending in
your program using the ILE functions (see
https://www.fieldexit.com/forum/display?threadid=551 for info). If you
want a nice interface, you could add MAILTOOL for the front end.

Halfway through writing this I realized that this is probably the situation
where you wanted to keep using the same commands you had before

Either way... the above are solutions. :)

Good Afternoon,

V7R5 pretty up to date on PTFs.

In preparation for no longer using gmail for email relay we're working with
a vendor to use a different relay. It so happens that the password is 69
characters long.

We have a couple Brother all-in-one devices that we (not often) email
documents to employees. They cannot handle passwords over 32 characters.
Also, our Tripplite UPS cannot handle passwords over 64 characters. No
problem, I thought. We'll just point them to the IBM i (in the cloud) and
the IBM i can relay.

I found this article from some fly by night author (haha):

https://www.kisco.com/ibm-i-security-tips/ibm-i-smtp-relay-controls-2.html

I used ADDSMTPLE to add 3 *ACCEPT entries:

IP Address Subnet Mask
192.168.0.0 255.255.0.0
10.100.0.167 255.255.0.0
10.46.0.2 255.255.255.255

I point the Brother email settings to our IBM i internal IP address and try
a test email.

Using port 25 gives this error at the Brother device

"Communication with the specified send e-mail server failed. It is possible
that the network is busy or there is some problem. Please try again later."

Using port 587 gives this error:

"The specified send e-mail server cannot be found. The Send E-mail Server
doesn't exist or the specified host doesn't support the service. Check the
Send E-mail Server name and port number."

Which leads me to believe that I am reaching the IBM i when using port 25
because the error is different.

I also tried it with the IBM i email relay to the not recommended
ALWRLY(*ALL) in case I fubared the ADDSMTPLE stuff. Same errors.

A support person had me install Putty and connect to the IBM i on port 25.
Got a blank screen with no welcome message. We did the same thing with the
service we're going to be using and got a welcome screen that said the
service was ready. The support person felt that the IBM i was not
listening on port 25.

However, the Work with IPv4 Connection Status screen shows that it is.

Remote Remote Local
Opt Address Port Port Idle Time State
* * 21 020:47:45 Listen
* * 23 001:36:23 Listen
* * 25 000:04:35 Listen

I then tried with port 26 and got a "connection refused" message. So I
think I am connecting on port 25.

I'm guessing the issue is on our IBM i, but don't know what else to look
at.

Suggestions?

Thanks.
