# From

> [HTML Version](from_emailx.htm)

_from  _([String](string.htm.md), optional)  specifies the email address of the sender. This is optional because it is likely to be the same for the entire application and thus can be specified in the configuration file via the RTNADDR parameter. If specified here, it will override the configuration file. Note that this is the address that will receive messages from the SMTP server itself about problems delivering the mail.

**History**

2024 February, A-Shell 6.5.1755, EMAILX.SBX(147) and (148):  The RTNADDR directive and _from_ parameters can now include descriptive names, such as Big Brother <bigbro@us.gov> instead of just bigbro@us.gov. Also, a descriptive name included in the _from_ parameter or RTNADDR configuration file directive will now appear in the header seen by the recipient, if no explicit "From:" clause is included in the _header_ parameter. Previously, if not specified explicitly, the recipient would see only the unadorned version of the _from_ address, e.g. name@domain.
