Abstract RU 2449474 C1

FIELD: information technology.

SUBSTANCE: need to return an acknowledgment message is determined in accordance with a different value of the acknowledgement request field in a request signal. Using a SMTP interaction status code in the request signal as a criterion, if the value of the acknowledgement request field is established as "NO", then there is no need to return the message, and if "YES", the message has to be returned. Based on the response status of the acknowledgement signal, it is determined whether the SMTP transmission status code, sent back by the acknowledgement signal, is obtained.

EFFECT: protection of readdressing messages from duplication during multimedia message interaction.
