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.
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.

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.
