Any decent SMTP client should be able to send multiple messages over a single connection. You could capture the traffic with Wireshark. Set the capture filter to only grab SMTP traffic to that server's IP address. Unless it is going through SSL/TLS, you can read the handshake messages. They will look something like this: -----8<-------------------------------- 220 lists.php.net ESMTP Postfix EHLO ashleysheridan.co.uk 250-mail.php.net 250-PIPELINING 250-SIZE 10240000 250-VRFY 250-ETRN 250-STARTTLS 250-AUTH LOGIN PLAIN 250 8BITMIME MAIL FROM:<ash@xxxxxxxxxxxxxxxxxxxx> 250 Ok RCPT TO:<php-general@xxxxxxxxxxxxx> 250 Ok -----8<-------------------------------- The lines beginning with numbers are the server's responses. All of them should be ASCII/UTF-8 text. There is one other possibility. According to the RFCs, the standard line ending for email is CRLF. Make sure your system is sending both characters after each line. There is a slim chance the server is cutting you off after some number of bytes if you are only sending a LF.
