RE: How do I change SMTP mail relay server?

To get the firewall and Mail Router parms, I would need to change the Email Directory Type from *SMTPMSF to *SDD. Would that be a problem?

With *SDD setting, I see this in CHGSMTPA:
User ID prefix . . . . . . . . QSM
Address . . . . . . . . . . . QSMRMTAD
System name . . . . . . . . . TCPIP
Alias table type . . . . . . . *SYSTEM
User ID delimiter . . . . . . . '?'

Would I need to make any other changes somewhere when I change from *SMTPMSF to *SDD?

Set Firewall to *YES, Mail router and Forwarding hub server both to your new router.

You didn't mention if there is any SSL/TLS or authentication needed. Since you're using an in house relay to talk to outlook.com servers, I would guess not.

Tip... try to use host names (it smtp.yourdomain.com) that resolve using DNS vs IPs or host table entries. Bad practice.

Set up DNS servers in CFGTCP option 12, get the host names to use (like your PCs do) and use them.

Having worked with thousands of customers, setting up email and other things with hard coding IPs and using host table entries have been the biggest pain the rear for most of them. When the IP changes, there's a scramble to figure out why things stopped working. With host names resolvable with DNS, that shouldn't be an issue.

For many years we've relay-routed our IBMi-generated emails to an
internal email server on a Win10 box (MAILSVR1), and that's worked
fine. Now TPTB have set us up with hosted outlook.com server. To test
it, we've set up another internal mail server on a separate Win10 box
(MAILSVR2). I know that I need to change the forwarding hub info.

MAILSVR1 receives email from the i and relays it to the outlook.com
server
MAILSVR2 will do the same thing, once I get the forwarding hub working...

Here's what we have that works in CHGSMTPA, using MAILSVR2:

Autostart server . . . . . . . . *NO
Clear e-mail on start-up . . . . *NO
E-mail directory type . . . . . *SMTPMSF

Max outgoing e-mail messages . . *DFT
Keep until . . . . . . . . . . . *DFT
Maximum e-mail message size . . *DFT
SMTP domain alias . . . . . . . *NONE


However, when I change the FWDHUBSVR value to 'MAILSVR2' and restart
the smtp server, the email is still routed to MAILSVR1. Both MAILSVR1
and
MAILSVR2 are defined in CFGTCP option 10, Host Table Entries, and are
pingable.

What else should I look at?

Thanks
