# EMAILX Adminisetera

**Requirements**

The requirements for using EMAILX are:

·	The minimum supported version of A-Shell is 6.4.

·	You must have an SMTP server which is within "routing distance." That is, EMAILX needs to be able to open a socket connection to your SMTP server. The SMTP server may be on the same machine as A-Shell, or on the local network, or at your ISP connected via a full-time connection. Wherever it is, it must accept mail from you. Note that most SMTP servers have filters to protect against unauthorized users.

·	EMAILX supports several methods of SMTP authentication. See [AUTH](auth_emailx.md) for more details.

·	For secure connections (see [SECURE](secure.md)), EMAILX requires the LIBASHTLS library to be installed along with the A-Shell executable. LIBASHTLS in turn requires the GNUTLS package. This is typically pre-installed or available via yum for Linux. For Windows, it is available as a set of DLLs; contact MicroSabio for assistance. LIBASHTLS is not currently available for AIX.

**Licensing**

EMAILX is not included in the general release of A-Shell. It is, instead, an add-on option which is purchased and licensed separately. For additional information on pricing, licensing and purchasing, [contact MicroSabio](https://microsabio.com/contact-2/) or see the price list at [microsabio.com](https://microsabio.com).

Like all external subroutines (SBXes), EMAILX is written in BASIC. Source code is included with the license.
