The default setup for qmail is to give a temporary error from qmail-local
if a file system quota is exceeded while trying to write to a mailbox.
The following patch is a diff against qmail-ldap-1.03-20020801 which will
allow you to define QUOTABOUNCE in your LDAPFLAGS.
i.e.
LDAPFLAGS=-DQLDAP_CLUSTER -DDASH_EXT -DEXTERNAL_TODO -DQUOTABOUNCE
The patch from the qmail.org site from Jeff Hayward won't work due to
modifications for the automatic creation of maildirs so I simply modified
it slighty and made it more user-friendly via a define. This may be nice
for anyone managing disk space by having file system quotas. Your
incoming queue may fill very quickly with the default behavior of a
temporary failure and later retry (still in queue)!
It would be nice to add this into the stock patch in the future. Any
replies feel free to send back directly to me.
