Notices not being sent to postmaster

[Daniel Bowen]

Hello, any suggesstions for why MailScanner is not sending mail to the postmaster, though I believe I've done all the proper settings for it.  I am including a segment of MailScanner.conf and the Mail.log:
Thanks,

MailScanner.conf

# Notify the local system administrators ("Notices To") when any infections
# are found?
# This can also be the filename of a ruleset.
Send Notices = yes

# Include the full headers of each message in the notices sent to the local
# system administrators?
# This can also be the filename of a ruleset.
Notices Include Full Headers = yes

# Where to send the notices.
# This can also be the filename of a ruleset.
Notices To = postmaster at ortn.edu

# Address of the local Postmaster, which is used as the "From" address in
# virus warnings sent to users.
# This can also be the filename of a ruleset.
Local Postmaster = postmaster at ortn.edu
