SMTP Session
SMTP Send Session
Build a complete SMTP mail transaction, including message DATA.
Usage guide & examples
Connect with the SMTP Connection tool first. EHLO identifies the client and lists capabilities; MAIL FROM sets the envelope sender; RCPT TO sets the envelope recipient; DATA begins headers and body; a single dot ends DATA; QUIT closes the session.
Wait for 250 after EHLO/MAIL/RCPT, 354 before message data, 250 after the final dot, and 221 after QUIT. Headers and body are separated by a blank line. Lines starting with a dot are escaped automatically.
For attachments, HTML or multipart, open MIME Builder and paste its raw message into the optional MIME field. Envelope addresses control delivery; From/To headers describe the message and can differ.
Processed locally. No input is uploaded or stored.
Scope
Executing this session submits a message after DATA and the terminating dot. The page only generates text. Envelope MAIL FROM/RCPT TO and message From/To headers are separate; pasted MIME headers are preserved.
Send commands one at a time and check each server reply. Authentication or relay policy may be required.
