Install OpenSSL to c:\OpenSSL-Win32 or c:\OpenSSL-Win64, depending on the bitness.Strawberry Perl Releases (I use the ZIP edition which doesn’t require an installation).

In order to accomplish all of the above on Windows Server or Windows 8.1 or 10, you need to download and install the OpenSSL client and Perl (I use Strawberry Perl):

Neat! :) How to install OpenSSL and Perl on Windows Protip: Here’s how to send authenticated SMTP email over TLS from WordPress! And how to send authenticated SMTP over a TLS encrypted connection, in PHP, ASP and ASP.NET.

If all goes well, the SMTP server reports a successful authentication: 235 2.7.0 Authentication successfulīecause the username and password combination is base64 encoded, and is sent in plain text, you need StartTLS/TLS encryption to secure your SMTP connection. Use that to authenticate: AUTH PLAIN AHVzZXJuYW1lQGV4YW1wbGUuY29tAG15X3Bhc3N3b3Jk Your complete username and password log-in information is wrapped in the base64 encoded string. The SMTP mail server supports the authentication mechanism you want. Here you notice AUTH PLAIN LOGIN as a log-in method. Use EHLO to let the SMTP server print out the supported verbs: EHLO there This means you can start your SMTP transaction. When the connection is made, you’ll notice an SMTP 250 code: This gives a lot of verbose output, don’t worry :)

In bash you now can use the openssl command, as explained below, to set up a TLS encrypted connection with your SMTP server: openssl s_client -connect :25 -starttls smtp You don’t necessarily need Perl to generate a log-in hash, you can use Bash too: echo -ne | base64 Connect to an SMTP server with openssl in bash The base64 encoded string will be something like: AHVzZXJuYW1lQGV4YW1wbGUuY29tAG15X3Bhc3N3b3Jk SMTP AUTH log-in information with Bash To create the combination – which has to be base64 encoded – you can use Perl: perl -MMIME::Base64 -e 'print must not forget to escape the char with a slash ( \), otherwise it’ll be interpreted as an array. Normally this is an email address and its password. The log-in information is your usename (email address) and password, and a special character \0. Sudo yum install openssl Create SMTP AUTH log-in information with Perlīefore you can test the SMTP AUTH PLAIN authentication over TLS, you need to create log-in information. To verify SMTP authentication over TLS, you need the OpenSSL client: sudo apt-get install openssl Most SMTP and mail sending problems come from the fact that either the username and password log-in combination is incorrect, the mail server doesn’t support StartTLS, or the authentication mechanism used is wrong.īeing able to verify (Start)TLS encrypted connections with OpenSSL, and SMTP AUTH options, is ideal for when you’re having problems with email forms that send email using authenticated SMTP, over an TLS encrypted connection (fom a website). Test TLS connections and SMTP AUTH from the Linux and Windows command line They use X.509 certificates and hence asymmetric cryptography to assure the counterparty with whom they are communicating, and to exchange a symmetric key. Transport Layer Security (TLS) and its predecessor, Secure Sockets Layer (SSL), are cryptographic protocols which are designed to provide communication security over the Internet. SMTP Authentication, often abbreviated SMTP AUTH, is an extension of the Simple Mail Transfer Protocol whereby an SMTP client may log in using an authentication mechanism chosen among those supported by the SMTP server. SMTP Authentication is the mechanism by which the clients of an ISP identify themselves to the mail server through which they intend to send email.

This post shows you how to test SMTP servers, verify SMTP authentication and StartTLS encrypted connections from the Linux and Windows command line. When investigating SMTP authentication issues, particular over TLS encrypted SMTP connections, it’s always handy if you are able to test the SMTP authentication and StartTLS connection. How to test SMTP authentication and StartTLS using the command line?
