Subject: Sendmail can drop incoming mail from Berknet.
Index: usr.lib/sendmail/src/{deliver,srvrsmtp}.c 4.2BSD
Description:
The mail connection between Berknet and sendmail can be flakey.
Incoming mail may be lost. Complaints from MAILER-DAEMON may or
may not be generated.
N.B. this problem is related but not identical to the `bug' fixed
in version 4.21 (11/1/83) of /bin/mail.
Repeat-By:
The following command should deliver the arbitrary message read from
STDIN. Instead, the message is neither accepted nor returned; there
are vague complaints of "Bad usage" and the message is lost.
% /usr/lib/sendmail -v -T10-11 -oee -r <from> -h 1 <to>
Fix:
