Multi-Email Sender is a software which sends e-mail to a list of e-mail adresses in HTML or plain format. What differs from a standard e-mail tool is that it does not need any specific configuration: It does not need any host name for sending e-mail (SMTP server). It acts as an SMTP relaying software. It does not need DNS name setting : It retrieves the DNS number automatically. The software is a must for organizations which sends periodic e-mails to a mailing list. It has a control mechanism which validates e-mail addresses in the list, separates the failed and the successful ones into the text files and generates a log file for errors occured.
