Re: How do I change SMTP mail relay server?

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.

If you want to bypass using an in house relay and go directly to outlook.com
or office 365/gmail/etc our MAILTOOL solution has been ahead of the curve
for a long time as far as functionality, flexibility, ease of setup and
debugging,etc. www.bvstools.com/mailtool.html

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:

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
