I have a SMTP-server, for the purpose of this question lets call it: smtp.mydomain.com.
How do i check if the SMTP-server is in working? Can I send emails manually from Linux commandline?
This question is related to

Not sure if this help or not but this is a command line tool which let you simply send test mails from a SMTP server priodically. http://code.google.com/p/woodpecker-tester/
The only thing about using telnet to test postfix, or other SMTP, is that you have to know the commands and syntax. Instead, just use swaks :)
