Ed Wildgoose:
How safe is maildrop with simultaneous deliveries?
Very. I've never had any "accidents" in many months of using maildrop on
an 1150+ user site (low volume, though). There's no reason why there
should be.
I have a vmail setup where all users get a single home dir
("/home/vmail/domain.com"), and then their maildirs are in subdirs of
this single home dir.
More or less the same here.
What are the risks of letting postfix try to deliver 2 or more
simultaneous virtual deliveries to this setup?
On my site. Postfix hands to dspam, which hands to maildrop. Postfix
doesn't deliver the messages, maildrop does.
Note: I use a bunch of xfilter commands and otherwise flex maildrop
quite a bit. So the question really is whether maildrop is creating any
named temp files which are going to be clobbered by another simultaneous
instance?
Each message that is created is unique and no xfilter rules I know of
create conflicting tmp files (apart from transient files in subdirs of
Maildir). Which would yours be?
Next question. If I have two domains in seperate home dirs THEN can I
do multiple deliveries? ie if there are temp files getting clobbered then
are they in /tmp or in the home dir?
maildrop runs as a separate instance for each delivery. AFAIK, unless you
have quite specific xfilter rules in which you yourself create tmp files,
none are created. And if you create your own tmp files, then you're
responsible for seeing to it that they are unique.
