Automated SMTP test for remote and local hosts
As many others, this script scratches a personal itch. I had to test mail delivery from multiple hosts and see whether delivery was possible with unauthenticated and authenticated mails.
Since the script needs to run on many hosts and getting the script and their components on the host is a issue that slows down testing. Also, I didn't want to worry about passwords being stored on the remote hosts. That is why this script is self contained and can be run over various hosts, directly over ssh without copying any files over.
Requirements
The script depends on wget, perl and bash. Other dependencies are from the smtp-cli package, but are generally installed on most hosts.
Running
The cost of having a self contained script is that passwords need to be injected to the script somehow. I didn't want to create a wrapper script that injects the passwords in to the script, so editing the script is mandatory at this time.
You need to edit the usernames, passwords and various other bits and pieces at the beginning of the script.
After that, running the script locally is pretty self explanatory:
bash smtptester.sh
Remote execution is just as straightforward:
ssh remotehost bash < smtptester.sh

My itch has been scratched and I shared this script so that anyone who needs to accomplish the same can easily do just that.
