When setting up a mail server sometimes its handy to be able to test from the command line.
This can be accomplished with telnet or openssl
Telnet
telnet mx.server.tld 25
ehlo my.hostname Mail From: [email protected] RCPT To: [email protected] DATA From: [email protected] Subject: Put your subject here Place the body of your message here then place a period on a line all by itself to finish the body of the message .
Testing SMTP/TLS with OpenSSL Client
openssl s_client -connect mx.server.com:25 -starttls smtp
ehlo my.hostname Mail From: [email protected] RCPT To: [email protected] DATA From: [email protected] Subject: Put your subject here Place the body of your message here then place a period on a line all by itself to finish the body of the message .
Testing SASL Auth
If the server you're trying to test supports SASL authentication you can test AUTH LOGIN as follows.
Step 1, get the encrypted version of your username and password
Username
echo -ne 'username' | openssl enc -base64
Output will look like this:
dXNlcm5hbWU=
Password
echo -ne 'password' | openssl enc -base64
Output will look like this:
cGFzc3dvcmQ=
Now connect with one of the methods listed above (Telnet or OpenSSL) Issue the ehlo command:
ehlo my.hostname
Now issue the AUTH LOGIN command, in this format: AUTH LOGIN <Encrypted username>
AUTH LOGIN dXNlcm5hbWU=
If the server returns a 334 like this:
334 UGFzc3dvcmQ6
Then enter your encrypted password
cGFzc3dvcmQ=
If the username and password are correct you should get a 235 response like this:
235 2.7.0 Authentication successful
