When I use mailx or sendmail (on RHEL 6.9, Perl v5.10.1) from within perl such as

qx( qq\cat $log | mailx -r $EMAIL_ADMIN -s "Exchange Backup Status $rp
+tdate" $SEND_TO\ );
[download]

I receive the email in outlook with the following in the body of the message:

Message-ID: <5a27f1a0.VRRIyXDBT0l57yCy%xxx@yyy.com>
User-Agent: Heirloom mailx 12.4 7/29/08
MIME-Version: 1.0
Content-Type: text/plain; charset=us-ascii
Content-Transfer-Encoding: 7bit
[download]

If I run the command directly from the o/s, or have the perl code create a shell script with this command that then gets executed, this preamble does not appear.

Anyone know what may be going on here? I really don't want to use packages for such a simple operation.

• Are you posting in the right place? Check out Where do I post X? to know for sure.
• Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:

  <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>

• Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
• Want more info? How to link or How to display code and escape characters are good places to start.
