SMTP stands on simple mail transfer protocol
Simple Mail Transfer Protocol (SMTP) is an Internet standard for electronic mail (e-mail) transmission across Internet Protocol (IP) networks
The default protocol commonly used in directory services is LDAP (Lightweight Directory Access Protocol). LDAP is widely implemented for querying and modifying directory services such as Microsoft Active Directory, Novell eDirectory, and OpenLDAP. It works over TCP/IP and is optimized for reading, writing, and searching directory data like user information, devices, and access control entries. Other protocols you mentioned have different roles: NTLM: Authentication protocol SMTP: Used for sending emails RPC: Remote procedure calls, often used with Windows services If you're working on systems that also involve email notifications or account provisioning via directory services, having a robust SMTP setup is equally important. For that, you might want to explore SMTPWire — a reliable SMTP service for transactional and bulk email delivery. Visit: smtpwire [dot] com It integrates well with systems that rely on LDAP or Active Directory and ensures your email alerts, verifications, and access-related communications are delivered reliably.
Most SMTP implementations support at least the basic set of SMTP commands defined in RFC 5321 — like HELO/EHLO, MAIL FROM, RCPT TO, DATA, RSET, VRFY, NOOP, and QUIT. These are enough for standard mail delivery and are almost universally supported. If you’re curious about extended commands (like AUTH, STARTTLS, etc.), they depend on the server’s configuration and what extensions are advertised in response to EHLO. WarmupSMTP Company
