Gumbo Mail is our rendition of the popular SendMail program, implemented on IBM i . It is a software utility that allows you to send email with MIME attachments directly from IBM i . With Gumbo Mail you can add timely, convenient and inexpensive email output to any application. Gumbo Mail integrates with IBM i's built-in mail support to provide delivery to any email recipient. All processing is performed on IBM i, providing a stable platform for generating email.


The main function of Gumbo Mail is accessed by running the Gumbo Send Mail (GSENDMAIL) command. The command creates a MIME compliant email message from the specified input and email address(es) and hands it off to IBM i for delivery using IBM i's built-in mail support. The command's features include:

Commands to help you trouble shoot and, optionally, automatically configure IBM i to send mail are also included with the product.

Gumbo offers two choices for licensing our IBM i software products, system wide licensing and partition licensing. These are mutually exclusive. A system wide license applies to a specific system serial number and processor group and is good for any and all partitions in the system. A partition license applies to a specific system serial number, partition number, and maximum processor capacity, and is not valid for a system that has not been partitioned. For the overwhelming majority of our customers, a system wide license (~ 98%) is the best choice. A partition license (~ 2%) is the best choice in very limited circumstances involving small partitions on large machines.

The system wide license prices for all of our products, with the exception of Report Designer, are tiered based on your system's processor group. You can determine your machine's processor group by running the IBM i Work with License Information (WRKLICINF) command.

The partition only license prices for all of our products, with the exception of Report Designer, are based on the maximum processor capacity configured for the partition (rounded up to the nearest tenth). You can determine your partition's maximum processor capacity by running the IBM i Start System Service Tools (STRSST) command and taking option 5 "Work with system partitions" then option 1 "Display partition information" then option 2 "Display partition processing configuration".

The one time charge includes the first  year of maintenance services. You are purchasing a permanent license to use the software subject to the terms of a license agreement and upgrade policy.

System Wide License (all partitions)
Processor Group One Time Charge Annual Maintenance
P05 $745 $115
P10 $1,045 $160
P20 $1,795 $270
P30 $2,995 $450
P40 $4,495 $675
P50 $5,995 $900
P60 $7,495 $1,125
Partition Only License (one partition)
Price Component One Time Charge Annual Maintenance
Base per partition $670 $100
Add per processor $750 $115
  1. The smallest unit of processor capacity is .1 (one tenth). For example, round 1.43 up to 1.5.
  2. Example partition only license: 1 partition with 1.43 processors OTC = $1,795 = $670 + 1.5 X $750.
  3. Run CALL PGM(QLZARCAPI) to see MAX PROCESSING CAPACITY: for a partition.
