Asked by zukinaru in Simple Mail Transfer Protocol (SMTP), E-Commerce Security, FreeBSD
My security staff made report that there's hole on my FreeBSD Server.
In his report, he said that "The SMTP Server supports one of the following authentication types: LOGIN, PLAIN, or PLAINTEXT. This means that credentials passed to this server could be sniffed and viewed by a third party."
so,my questions is How to make SMTP Server does NOT Allows Plaintext Authentication on My FreeBSD Server ?
Thank you.
