Old hardware dogs use newer tricks for mail

Mailbox in field
HP 3000s can surprise us with their tenacity. A consultant to a financial services company is managing mail exchange from an HP 3000. The work relies on the Telemon MAIL software, created in the 1990s by the well-regarded data transfer company.

Telemon gave the world the Typeahead Engine during the 1990s. The hardware device improved HP 3000 connectivity speeds. When the Internet rose up in the next decade, MAIL made its way into some 3000 shops.

In the years that followed, MAIL found a place in many other IT shops because it had been released into the wild. Stein said MAIL, installed on a 3000 today, shows as being from 1998. "They would like to send email out via a service, such as SendGrid, instead of a local exchange server."

The HP 3000 in the equation is timeless enough that it doesn't have a formal database. It uses Keyed Sequential Access Method files. "They are big on KSAM," Stein says. "KSAM is definitely a different animal."

Emailing data from a 3000 is a different animal, too. The Telemon software is at the heart of MAIL.MAIL.ESP from Beechglen. "Addressees can be configured with SETVARs," says Tracy Johnson from TE Connectivity. "It sends via our company exchange server and is routed from there."

"Beechglen's software uses Telamon's email program. MAIL was shareware. If SendGrid uses SMTP relay, I believe you can configure it to use SendGrid." Johnson offers to cut a DDS tape of MAIL and snail mail it to Stein.

Mark Ranft of Pro3K says, "I’ve used the Telamon mail.exe program for years. The mail hosting server must be configured to allow mail forwarding from the IP address of the HP 3000. Keep in mind, your mail/security teams may not permit this.

"I am not familiar with SendGrid, but it may allow mail forwarding. I see it has an option for Address Whitelist setting, which allows a specified email address or domain for which mail should never be suppressed."

MAIL and the Beechglen software were created by utility software firms. Meanwhile, Netmail/3000 was built by an Internet pro who focused on well, email: Chris Bartram at 3kassociates.com. Netmail was as full-featured and standards-based as an email package ever got on the 3000.

“They are big on KSAM” is a phrase I never thought I’d hear again. Of course, people think there’s no more MPE enterprise computing, either.

People have been deploying email for decades on MPE/iX. From 2009, this question sits on the Web: Is there a job stream for using Telamon's MAIL program that produces an email with multiple lines in the email body? 

Donna Hofmeister replies, "Put the body into a file, then use the '-m' switch. Alternatively, load the body text into a CI variable and cite/de-reference the variable when you run the program.

Additionally, take advantage of the variables that the MAIL program
recognizes:

MAILSMTPHOST
MAILFROM
MAILTO
MAILCC
MAILBCC
MAILSUBJECT

Using them will help shorten your run line.
