Sendmail, 3rd Edition

Name

MeToo

Synopsis

When you send mail to a mailing list that includes your name as a part of that list, V8.10 and later sendmail normally include you in the mailing, whereas V8.9 and earlier normally exclude you. This change in the default behavior was caused by a change in the standards.

The MeToo option overrides the default. The forms of the MeToo option are as follows:

-m                     ← command-line shorthand 
O MeToo=bool            ← configuration file (V8.7 and later) 
-OMeToo=bool            ← command line (V8.7 and later) 
define(`confME_TOO',bool)   ← mc configuration (V8.7 and later) 
Ombool                  ← configuration file (deprecated) 
-ombool← command line (deprecated) 

The optional argument bool, when missing, defaults to true (include the sender). If this option is entirely missing, V8.10 and later default to true (include the sender), but V8.9 and earlier default to false (exclude the sender).

The MeToo option is safe. Even if it is specified from the command line, sendmail retains its special privileges.
