Did some additional checking. Doing a dir from MIM to MAISA actually do work. So there is something funny going on with RHESUS.
Looking with tcpdump at the UDP packets, the one thing that looks a little different is that MAISA actually sends 584 byte length packets. Thinking about it, 609 is a rather odd value.
Since RHESUS is an I64, I'm ready to blame that modern junk. :-)
I can't spot what the problem is right now anyway. More to follow, I guess. Anyone else feel like trying to figure it out?

So it appears the data from RHESUS to MIM gets lost sometimes. In this
case just for doing a directory on RHESUS...
Looking at the UDP traffic, it looks like the packets are coming in to
Update, so it might be an issue with E11 (I've had an issue before where
it could drop ethernet packets under some circumstances).
But I'm not sure why it fails for you, Saku, since your traffic should
not pass by MIM anyway, even though it do pass through Update.
But anyway, it (for me) definitely does not look like I have problems
with packets being thrown away. Actually, the packet size of individual
UDP packets is 609 bytes. DECnet normally do not send lager packets than
defined by the EXEC parameter "segment buffer size" (or "buffer size" in
VMS). And the default for this is 576 bytes. Add some overhead to that,
and 609 bytes sounds reasonable.

I have no problem on copying files from MIM.
MTU issues on the internet uplink?
Nope. Whatever it is, I seriously doubt that is it.
Unless some firewall blocks fragmenting, the MTU is not really ever
an issue.
The error might be because of excessive lost packets. Maybe some
throttling could help. What files are you trying to pull? I can try
and experiment some.

$ telnet chimpy 143
Trying 192.168.77.246...

$ Set NoOn$ VERIFY = F$VERIFY(F$TRNLNM("SYLOGIN_VERIFY"))
What is going on? Why is the IMAP service outputting DCL code?
This is because either your system-wide login (SYS$STARTUP:SYLOGIN.COM) or your SYSTEM login (SYS$MANAGER:LOGIN.COM) is printing that out. (The IMAP server process runs using DCL, so whatever is in the (SY)LOGIN.COM files gets executed.)
Now, that said, VERIFY should be off by default, so I don't know why you're seeing it here. You don't have SYLOGIN_VERIFY defined to be 1, do you? (I don't think that would be the issue since the "$ Set NoOn" line was logged as well before the check in F$VERIFY().)

I'm trying to configure IMAP access to CHIMPY, and have turned it on in the MULTINET server.
I restarted the server, but when I connect to port 143 (IMAP), I get this:

What intrigues me is the NAMED process? Is this the DNS interface for other apps on CHIMPY, or is it an actual DNS server?
If the latter, how do I turn it off? MULTINET CONFIG/SERVER doesn't have an entry for it?
I believe that it is a caching DNS server used for client DNS queries.
I think that you can find it in MULTINET CONFIG/SERVER under "DOMAINNAME".
