Good software reaches further with the right partners. Whether you want to build on our technology, sell our solutions, or simply open doors for the customers you already work with - there is a level of partnership built for you.

If you’ve heard of BlueSeries - or you’ve been running BlueSeries express’it, BlueSeries Fax, BlueSeries Mail, BlueSeries FTP/XML, or the BlueSeries Web Client for years - you’re in the right place. We’re System & Method A/S, the Danish software company that has built and supported BlueSeries from the start. Today you’ll find it at the heart of Sitemule, our complete modernization ecosystem, running natively on IBM i.
BlueSeries was built to solve a problem that hasn’t gone away, only changed shape: how do you let an IBM i application send something - a document, an alert, an invoice - to someone outside the system, without introducing a separate mail server, FTP host, or piece of middleware that demands maintenance?
The original BlueSeries did this for fax in the 1990s, when faxing invoices and orders was how business communication actually worked. As the business world changed, BlueSeries changed with it - email, SMS, FTP, XML conversion, OIOXML and OIOUBL, and, most recently, “NemHandel” for Danish business document exchange when Danish e-invoicing standards arrived. New channels added, old ones still working.
The principle through every version has been the same: do it natively from IBM i. Generate the message, format the attachment, dispatch it, log it - all inside the operating system that already holds your business logic and data.
BlueSeries hasn’t gone anywhere - and it hasn’t stood still. Like its three other engines - IceBreak for web serving and applications, IceCap for screen transformation, and BlueNote for monitoring - BlueSeries has been reborn as an engine of Sitemule: the communications engine that powers native multi-channel communication across the platform, invoked as IBM i commands from RPG, COBOL, and CL, or triggered automatically from output queues.
Nothing you rely on goes away. BlueSeries remains a separately installed product and will continue to be fully maintained and supported - exactly as you know it today. Same engine, same conservative principle - keep communications inside the platform - same team, same phone number, same contracts, same invoices from System & Method A/S.
New opportunities open up. Because BlueSeries is now an engine of Sitemule, upgrading is a natural next step, not a migration project. Sitemule unites web serving, service-based architecture, screen transformation, messaging, and monitoring into a single browser-based Workspace - running natively on your IBM i. When you read about “native, high-performance communication” on our website, you’re reading about the next chapter of BlueSeries.
You don’t just get a fax solution anymore. As the communications engine of Sitemule, BlueSeries serves as the messaging layer across a full IBM i platform:
Multi-channel - email (SMTP, POP, IMAP), SMS (SMPP and gateway APIs), FTP and FTPS, fax, XML conversion including OIOXML and OIOUBL, and NemHandel document processing - all from the same engine, configured centrally.
Native integration - invoke BlueSeries directly from RPG, COBOL, or CL as native commands, or set up triggers on output queues to detect, format, attach, and dispatch spool files without programming.
Format conversion built in - PDF, TIFF, CSV, and TXT attachments generated and attached without external conversion tools.
Full IBM i governance - every transmission inherits object-level security and authorities, journals to Db2, and adheres to the same audit trail as your business logic.
Web Client - show, monitor, and resend transmissions from anywhere, for unlimited users.
All of it runs natively on IBM i, layered on top of the IceBreak engine. No external mail relays, no separate FTP hosts, no middleware tax.

BlueSeries is a product of System & Method A/S, founded in 1989 in Denmark. We modernized ourselves the same way we modernize our customers - our four trusted products are today the engines of Sitemule. This platform modernizes IBM i and brings a web-centric approach to the business applications running on it. All our software is developed specifically for IBM’s midrange platform lineage - AS/400, iSeries, i5, System i, and Power Systems - and the operating systems that have run on it: OS/400, i5/OS, and IBM i.
Still the only native web and application server built to serve the web directly from RPG and COBOL on IBM i - without middleware, and without rewriting a line of business logic. Twenty years on, we're still refining it
IceCap transforms 5250 green-screen applications into modern web interfaces - without touching a line of code. Now an engine of Sitemule. By System & Method A/S.
Built to watch every job, message, and subsystem on IBM i - and to act on them the moment something breaks. Alerts to your phone, auto-recovery built in, no external tools required
ZipSeries - zip and distribute IBM i objects, programs, and libraries with full security intact. Free edition available. Still supported by System & Method A/S.

Managed IBM i hosting from System & Method A/S - 24/7 monitoring, zero-downtime migration, IBM service agreement, CO2-free. Now presented as Sitemule Cloud.
