Comment chars MTA option

File format and file handling options
The  MTA option controls what characters are taken to signal a comment when they appear in the first column of various MTA input files. The value of this option takes the form of a list of ASCII character values in decimal. In Unified Configuration, such a list is space separated: msconfig&#x3e; show -default mta.comment_chars mta.comment_chars: 33 59 In legacy configuration, the default was the list {33, 59}. With either representation, this specifies exclamation points and semicolons as comment introduction characters.

As of 7.0.5, note that the  MTA option only truly controls which character(s) in addition to semicolon (ASCII value 59) represent comment introduction characters, since regardless of whether or not it is explicitly set (or shows up in the value of  ), the semicolon will always be treated as being set in.

Note that the  option does not apply when reading the  legacy configuration MTA option file itself as this file is read before   has even been seen. For this file, the following comment characters are "hard-coded": " ", " ", and " ".
