SMTP Route Through
We have set-up Good-Clients and placed node names/IP addresses into this list. The problem is that most ISP's do not set-up statis addresses or node names, so when these change the SMTP.CONFIG file must be edited to reflect the changes.
Does anyone have a better solution? Each user does have a unique VMS acocunt, but the SMTP server does not appear to utilize this for route through traffic.

Re: SMTP Route Through
The TCP/IP Services package is comparatively limited in its support for modern SMTP-related features and mechanisms; I'd investigate one of the third-party IP stacks, or an alternative mail server.

Re: SMTP Route Through
I omitted part of the "puzzle", we travel all over the world and many times are connecting through customer networks. The allowable protocols can be very restricted.
We have installed a web based mail server on the OpenVMS system, but web based mail message creation has limited functionality and does not integrate well with OUTLOOK.

Re: SMTP Route Through
Here, I'd start to investigate alternatives to the SMTP server you're using, and I'd certainly suggest you make your product requirements known to HP here. This given that the current configuration is not meeting your requirements here, nor was your previous quest for spamassassin or analogous apparently fruitful. One of the other common pieces of this - ClamAV - is around as an add-on, however.
If you can't use a VPN or tunnel, then Gmail or other such (directly or as a route-through) might be an option, and HP often helps its customers move to Microsoft Exchange server, for instance. OpenVMS Engineering has featured the Quintara SecureServer product, and the Process IP stacks are certainly in wide use on OpenVMS.
Yes, I know, (still) not the answer you wanted... Sorry.

Re: SMTP Route Through
We'll have to start looking more closely at LINUX.

Re: SMTP Route Through
Of course this would require an extra action at boot or a click of the user.

Not just that. You'll have to restart SMTP.

Re: SMTP Route Through
I regularly use these tools to connect from the local Mac OS X client boxes through onto various OpenVMS boxes and onto other server boxes. These approaches can also permit DECwindows X connections and displays sent back from OpenVMS out onto the Mac client, for instance.
If you're interested in discussing a particular implementation of this approach, contact me off-line.

Re: SMTP Route Through
1) CommunigatePRO does not seem to support OpenVMS, at least it is not mentioned as a supported system.
2) To obtain IP addresses, our users log onto the VMS server using a telnet client. They then enter $SHOW TERM and the IP address is displayed. This is then added to the Good-Clients list. We probably should automate such using a script on the PC's and a DCL command file on the VMS mail server. Maybe using PHP and APACHE?
3) SMTP does not need to be restarted when changes are made to the SMTP.CONFIG file that impact GOOD_CLIENTS. The changes are picked-up "on the fly".
4) We will look into VPN through our firewall router. As I understand VPN, each connection is a unique network, so each PC would have to map to a unique network, I suppose that the network masks could be set to minimize the number of nodes possible in each network. Since almost all of our users connect via NAT (and our router utilizes NAT), the VPN functionality needs to be in the firewall/router, or special software is required on both sides. Additionally we will have ensure that out firewall supports a large enough number of VPN's.
5) We have attempted to use X-Windows through VPN's. Unless one has local high performance connections the performance was unacceptable. To get reasonable performance LBX (Low bandwidth X) needs to be installed. HP has a kit for this for VMS. We did not have enough resources (time) to get things working acceptably.
