I get a lot of system alerts related blank mails. The custom scripts send empty mails when there is no issue found on the server.

How do I filter such mail? I know how to filter using "From" and "to" fields. I need to know if there is anything in the contents tag.

All of the available search operators are listed in GMail advanced search help. There's no standard wildcard selector to put into Doesn't have but according to a question about wildcards you can use Perl RegEx for query. This way, you need to construct a query that searches for the absence of any character in the body.

  • And how do you check if the body of the mail is empty?

  • You check with the parameters that aren't empty, such as From and Subject.

  • The OP stated that the script sends empty emails, so how do you check for this situation—if an email’s body is empty or not? That is the OP’s question.
