[Dovecot] Newbie: unable to access mailbox more than once

[Matt Petoe]

Ahhh, okay - I presumed that 'dotlock_try' required something else to 
'try' after....

Replacing 'dotlock_try fnctl' with just 'dotlock_try' seems to have 
fixed my problem.

The idxview & logview tools are useful to learn about. Thanks.

thanks again
