How to deliver mails in the stage directory after a crash ?

[Pierre POMES]

Hi all,

I plan to move from WU Imap to Cyrus Imap, for better performance, for 
subfolders, and so on. Actually, I do some tests with Cyrus imap before 
using it for everybody in the company.

Everything was fine during 2 days, but yesterday, a lot of emails have 
to be delivered, and all lmptd process (134 exactly) became frozen on DB 
errors : lmtpd[9300]: DBERROR db3: 134 lockers

I know the global performance depends a lot of compilation options used 
in the configure script, so I do not really worry about this problem.

My question is : after one hour, all lmtpd process were still frozen, so 
I killed them manually (what could I do else ?), and all mails stayed in 
the "stage." directory. Is there a way to retry the deliver of all 
theses mails ?

A crash can occur, a power supply loss can also occur, that's why I am 
really interested in the deliver recovery for email stored in the stage 
directory.

Thanks for your help,
Pierre
