Bash – Sending email through Gmail with mailx gives error “Send options without primary recipient specified”

bashemailgmailmailx

I am trying to send an email with a Bash script with my Gmail account using mailx. I have the following code in the script: 

mailx -v -s "$SUBJECT"  
-S smtp-use-starttls  
-S ssl-verify=ignore  
-S smtp-auth=login  
-S smtp=smtp://smtp.gmail.com/587  
-S from="$SENDER"  
-S smtp-auth-user="$SENDER"  
-S smtp-auth-password="$PASSWORD"  
$RECEIVER

This gives me the error Send options without primary recipient specified. I thought the last line was the primary recipient. How can I send this email?

I just had a similar problem.

In my case it was due to a newline at the end of an email list causing mailx to receive an empty address.
