DJB was or is a (Free)-BSD user (when he started, Linux was a toy anyway), which back in these days had this problem. Agreed, however his Maildir approach did not include hashing in any way shape or form, so how did file systems back then handle over 1000's of email messages in an Inbox? Poorly. I had a server stall after a user stopped checking mail and accumulated 100,000 messages in a single folder. The filesystem was basically unusable. That was on FreeBSD 4.6, IIRC. Once I cleared that up, the mysterious slowness in general of the machine disappeared. -- Jon
Re: [vchkpw] Why is vadduser creating a hierarchy?

I only have about 7,000 users to manage and would rather NOT subtree (whatever the term is) this user hierarchy. Be sure your filesystem can handle this. Certain filesystems (ffs for example) can take a major performance hit with a large number of files in a single directory. What logic controls when vadduser decides to subtree the folders for a particular domain? When running configure: --disable-users-big-dirDisable hashing of user directories. -- Jon
Re: [vchkpw] User quota over NFS
On 7/18/06, Darek M [EMAIL PROTECTED] wrote: Incoming mail is handled by separate MX machines. They in turn mount the vpopmail directory from the main system via NFS, so they have access to the same vpopmail binaries and domain directories. So they are using the vpopmail install from the main system. However, when a user is over 100%, mail continues to be delivered into the inbox. Does anyone have any info on this? A fix? You might need Bill Shupp's qmail Maildir++ patch, it has solved similar issues for me: This patch adds maildirquota (Maildir++) support to qmail-pop3d and qmail-local. It was created because when vpopmail switched to maildirquotas, a user's quota usage was not decreased after deleting mail via qmail-pop3d. Also, because .qmail files would allow qmail-local to write directly to a Maildir whithout piping through vdelivermail first, quotas were not effective for aliases. Actually, this was the case with vpopmail's old quota system as well. http://shupp.org/patches/qmail-maildir++-universal.patch -- Jon
[vchkpw] maildirquota.c patches against 5.4.15
I believe this fixes most of my problems with weird quotas showing up
in maildirsize files, as on some systems long and off_t are not the
same. The %lld in the sprintf (bottom of the patch) may not be
correct on all systems but was required in my case, as off_t is
typedef'd as long long.
