MailOnBoard Plus

MailOnBoard Plus is an easy-to-use and cost-competitive email service via Inmarsat, Iridium and VSAT satellite systems for crew and/or B2B usage.

The service is also available for mobile devices with Android software.


MailOnBoard (MoB) is a novel tool developed by Otesat-Maritel for the corporate email correspondence between the office and the vessel.

MailOnBoard enhances the capabilities of the most widely used e-mail services at the office (e.g., MS Outlook, etc.) by applying an appropriate corporate e-mail policy framework, turning them, in essence, into a typical "maritime e-mail" application.

The service incorporates a strong compression mechanism that effectively reduces the size of incoming or outgoing e-mails at up to 90% resulting in corresponding communication savings. The service also provides corporate domain name hosting, runs on a regular PC, and manages e-mail communications over a dial-up or broadband internet connection, whereas MS Outlook, Outlook Express, Mozilla, Thunderbird or any other SMTP/POP3 clients are supported.

With MailOnBoard the user can send and receive automatically e-mails with plain text and/or attachments, and provide a dedicated e-mail account for each vessel. With the installation file being around 2 MBs it can even be sent via e-mail on board.

MailOnBoard also provides remote management and self-controlling of the vessels’ e-mail communication via a user-friendly Web Interface that can be accessed through public internet.

MailOnBoard Plus

Mail-on-Board (MoB) plus is the multiple accounts version of MailOnBoard that could also be combined with pre-paid crew cards. The service also includes a powerful compression mechanism of the transferred data volume that significantly reduces the size of e-mails at up to 90 % (depending on the file type). The service is based on the client–server architecture via utilizing appropriate equipment on board. The MailOnBoardPlus installation to the Local Area Network (LAN) is particularly convenient, and does not require any sort of equipment to the corporate office.

MailOnBoard Plus service is accessed onboard through a user friendly Web interface without the need of client s/w installation. Besides, it is designed to offer accessibility to users using even SMTP/POP3 or IMAP clients, enabling them to take advantage of MoB protocol features. The user account profile is synchronized at a server on shore, and thus it can be accessed by crew users even when being ashore.

On customer’s option, the service can be integrated in the S@tgate platform avoiding using extra hardware equipment on board.

MailOnBoard Plus is also available for mobile devices with android software.

The application, developed by Otesat-Maritel, enables the crew to exploit the capabilities of MailOnBoard Plus service by sending and receiving e-mails with attachments onboard, via their android mobile devices, with corresponding data compression, reaching up to 90%.

The application also supports common SMTP/POP3 clients (eg. gmail, yahoo etc).
