Are you sure this log is of your libcurl based app?

Whilst I recognise RSET as a valid SMTP command, this command is not
currently supported by libcurl's SMTP module (Please feel free to have a
look in lib\smtp.c yourself).

The currently supported commands are:

EHLO, HELO, STARTTLS, AUTH, MAIL FROM, RCPT TO, DATA and QUIT

Whilst I have thought about extending the supported commands to include
RSET, NOOP and VRFY I have not made a business case for it at the moment.

As such you have me totally stumped as to what could be sending that RSET :(

Kind Regards

Steve
