hi.  I am trying to configure mail on the iSeries or AS400.   My only ISP I have access to is verizon.  They have no SMTP servers you can use.  How can I configure the system to send out mail?  I am have other questions concerning this, but can't seem to find one if you have no access to an smtp server.

How do you send mail for the rest of the organization?

Been a long time, but with the iSeries, we didn't configure our box to connect directly to the internet. It was configured it to connect an internal Exchange Server. Need port assignment, credentials, and the such. Last time we set this up, had to be about 15-20 years ago.

Our mail is hosted with zoho.com.  No internal exchange server.  Pretty old system.  V4R4 is the OS level.

V4R4??  Wow that is old!

Verizion is your ISP, not your email provider. ZOHO SMTP info is probably what you need to provide.

Please read the links (especially IBM tag) below to see how others handled this. I can't provide more detailed response since we no longer have our iSeries (got rid of 4 years ago now).

I will check out the links.  The main issue it appears is also is that the iSeries can't the SSL port that most email providers need.  (I think, but not positive about that. )

Here are step-by-step instructions for V6R1 forward.  V4R4 is so far out of support, IBM has dropped the online documentation from most places.  No idea if this will work that far back.  If it doesn't help, let me know and I'll try to dig up some old documentation.

I have looked at that document.   It's too vague on the mail2.company.com.  Gives no info on using SSL which most mail providers require.

You want to send email FROM your AS/400 to one or more outside mail servers, right?  That;s called "relaying" mail, and there is just one destination port that you use: port 25.  That's not to say that you can't configure a mail server to receive mail on additional ports (public mail hosts do that sometimes to bypass ISPs and organizations who block outbound port 25 as an anti-spam measure).  

But if you plan to relay mail over the internet to strangers, you'll be talking to port 25 on the destination server.  

Very few public mail servers currently REQUIRE SSL/TLS encryption, but the number is slowly growing - so an old V4R4 system probably isn't appropriate for production use as a mail server for much longer if you need to talk to mail servers outside of your organization's control, since IBM didn't add support for SMTP over TLS/SSL or SMTP authentication until V6R1.

Here is an old V4R3 article that explains mail configuration:

If you're confused about specific entries, provide some info about the domain you are trying to configure, and I'll help.

Yes, the plan is to email from the AS400 to strangers.   I will take a look at that doc.

Did you end up finding a solution?

I just thought I'd link the comment I added to your other post:

Using the workaround, here:

In your example, you'd skip the Gmail stuff (as you'd be sending to Zoho).
