Part 1 – AT Commands for All Universal IP Devices

Chapter 2 – SMTP AT Commands

#PUTMAIL – Send Mail to Recipient with Interactive Mode

Description: This command allows the attached host to send an email message containing body text passed to the TCP/IP stack over the serial port. Once an IP link is established, the attached host can send an email message at any time (except when the TCP/IP stack software is already in a process using TCP resources).

The header of this email is built using the REC1, CCREC1 and SUBJ1 parameters.

This command is similar to a “send email” operation issued by a standard messaging client on a PC.

Syntax: AT#PUTMAIL

IMPORTANT NOTE:

You must issue the <CR><LF> bytes (binary value: 0D 0A) as the first data bytes if a header is NOT being constructed in order to finish the internal headers correctly. This mechanism is in place to allow for the addition of custom headers such as MIME data.

AT#PUTMAIL	#CME ERROR: <value>
	Notes: An error has occurred during the communication with
	the remote SMTP server. It may also happen during
	the data transfer (after the OK message).
	This error can be due to one of the following
	reasons:
	- DNS servers are not able to resolve the SMTP
	server address.
	- SMTP server is temporarily out of service.
	- Authentication (SMTPUN, SMTPPW) is not valid.
	- An email address specified in REC1 or CCREC1
	is not valid.
	- n = inactivity period of 50 seconds on the serial
	port.
	See section ‘Response messages and error codes’

To view parameters, use #VMAIL and #VSMTP. They are also listed in #VMAILi (where i = 1, 2, or 3)
