Bug#2844: sendmail configuration: Cw $mailname dangerous
Package: sendmail
Version: 8.7.5-3
The script in /usr/sbin/sendmailconfig creates a Cw entry for the
mailname of the system. This can cause problems with systems that
masquerade as a central mail name for an insitution. This happens if I
am running sendmail on a personal workstation which has only a subset
of the users from the central mail server. Such a machine can send
mail, and receive mail by mounting the mail spool from a central
server. However, it cannot deliver mail to all users known to the
central mail server (besides the locking problems which might occur
with an NFS mounted mail spool and several systems delivering mail).
Solution: The Cw entry should be optional. It can be prompted for with
the other equivalent names.
Cheers,
Lukas
