+As listed above. The path of the mail transport configuration
+file can be changed with the
+.B MHMTSCONF
+environment variable and augmented with the
+.B MHMTSUSERCONF
+environment variable, see mh\-profile(5).
+.SH BUGS
+Failure to open any mail transport configuration file is silently
+ignored. Therefore, it's best to avoid dynamic creation of such
+a file with the intent of use via the
+.B MHMTSCONF
+or
+.B MHMTSUSERCONF
+environment variables. If such use is necessary, the ability
+to successfully open the file should first be verified.
