I don't want to put duplicates into a seperate folder, I'd rather
delete them. At the same time however, I'm worried that a mail
might be incorrectly deleted because of the delivery problem /
requeue situation described above.
I keep backups of every non-duplicate. So if this happened to me, when
a requeued message gets lost (as happened yesterday--see the posts about
"Modifying a message..." then I can fetch the message from backup.
Is there a way to safegaurd against this so I can throw away
dupes with confidence that only dupes are being deleted?
The problem is, how do you know there's a message to fetch from backup?
Also, how high can I safely set the "maxlen" argument to
formail -D to? 8192 seems too low to me, and we have plenty
of disk space here. Thanks in advance.
A duplicate will generally arrive within a couple of days of the first
copy. Count the message IDs in msgid.cache and compare with your average
daily count. 8192 bytes holds a LOT of message IDs.
