Re: Power 8 IBM i 7.1 - SMTP tasks always fails

I didn't think it was important but now I read the comments I think the
following information might be of value. The old server had four network
interface ports but they were rolled up into one virtual IP so that traffic
could go to one IP address but be distributed across the NICs.

I presume SMTP was set to use that virtual IP.

The new server currently has only three network ports active at this time
due to issues with capacity on the switch. There is no virtual IP currently
set up. So I presume the permissions that SMTP had on the power 6 server
just did not work on the power 8 because there is no one IP address.

Once they made that change it worked. I would have thought that our support
personnel should have worked that out without having it escalated but I
can't comment on how complex this particular issue was and therefore
difficult to resolve.

Let's first understand what an "interface" is. Try this command:
NETSTAT OPTION(*IFC)
This will work with an interface. Once you get there you will quickly
understand what an interface is.
What I suspect happened when you restored to your new system is that you
changed your IP address. Perhaps to do a little side-by-side testing? And
your SMTP was set up to "bind specific". And it was bound to the IP
address of your old system.

I have quite a write up on other stuff you may want to check, to which
some others have contributed:
https://wiki.midrange.com/index.php/Change_IP_Address

Now, if you have multiple interfaces, which all of our partitions do, you
may run into problems if some of the other interfaces want to use their own
SMTP (like Domino) and you're already bound to that interface with the
system SMTP.

Just to close this discussion

After escalation to level 2 support the problem was fixed. The fix was
apparently




Using the web navigator



1) click on NETWORK

2) click on SERVERS

3) find SMTP on the right side

4) Mark and click on properties

5) click on Bindings tab

6) *Enable Use all interfaces..*



Final step is to start SMTP services.


commands used for testing :: SNDSMTPEMM & SNDDST *LMSG.


No idea why this didn't work after a dump and restore but just glad it's
working now.

If they truly did this, then we wouldn't be seeing any differences in
CHGSMTPA, etc.

The telnet idea was a good idea for a test.

The list strips images. Pasting images to imgur.com and pasting the
link from that works quite well. OTOH, if they are 5250 images
copying and pasting the text instead of a screen shot is a fine option.

What do you see with WRKPTFGRP?

We recently migrated from a Power 6 server to Power 8 running IBMi 7.1
by just dumping the entire system onto tape from the Power 6 and
restoring to the Power 8. I think that is what the support guy said they

did.

Anyway the applications runs fine but we having problems with sending
email. The admin guy starts the job (?) that processes email and it
dies pretty soon after with no error messages.

Looking at the SMTP configuration it looks like it was on the Power 6
with the SMTP server name and port 25 so we just duplicated the
setting. The admin guy can send email fine by setting up a telnet
session to the mail server (which is just a relay) and issuing commands

so it's okay.

This is a screen I captured showing the SMTP jobs that failed.

From what I have been told it's the job QTSMTPSRVD in the screen
shot that

is failing.

Hard to get IBM support for this since 7.1 is out of support and we
might have to purchase extended support (which I don't mind) but I am
reaching out to the list in case somebody has an idea we could try in
the interim,

Thanks
