Can I restore from ctl_deliver -d?

[Alain Spineux]

Hi

You are very conscientious.
Because deliver.db only avoid multiple delivery of the same email in
the same mailbox,
most of us should have skipped this. Multiple delivery should be very
rare, happend only once, and without consequences.

Dou you know you can "expire" oldest entries in deliver.db using cyr_expire ?
This could reduce the time processing and maybe avoid errors.

Regards.
