Description Ben LaHaise 2001-07-10 00:55:01 UTC 
In more complicated system setups where /home is mounted via NFS, sendmail
fails to check  for the existence of the user's home directory when
checking if a .forward file exists.  This causes misdelivery of mail when
there is a temporary problem with the home directory (eg if the NFS server
is offline).  A suitable fix should involve checking that the home
directory exists and is readable on failure to open ~/.forward.
Comment 1 David Woodhouse 2001-07-11 12:38:37 UTC 
The suggested fix is implemented and works fine in Exim and Postfix.
Comment 2 Ben LaHaise 2001-09-26 21:48:47 UTC 
Is anything being done about this?
Comment 3 Florian La Roche 2002-04-07 13:56:25 UTC 
sendmail itself does not do any local mail delivery. Our default local
delivery is procmail, so I re-assign to this component in bugzilla.

Comment 4 Ben LaHaise 2002-04-07 21:20:10 UTC 
procmail does not perform .forward parsing.  Reassigned to sendmail.
Comment 5 Thomas Woerner 2004-10-21 14:35:38 UTC 
Please verify this with a newer version of Red Hat Enterprise Linux or
Fedora Core and reopen it against the new version if it still occurs.

Closing as "not a bug" for now.
