question on poptimeout

[Marten Lehmann]

Hello,

some of our users are grumping that they get the pop3 error:

-ERR [IN-USE] Unable to lock maildrop: Mailbox is locked by POP server

I know where it comes from and I understand that there must be a sort of 
locking for pop3. But sometimes users seem to get an authentication 
error and are asked by their mail clients to enter the password again. 
Then, when they retype they get the error. I don't know what makes the 
login failing in the first try (it only happens every now and then). We 
are using sasldb2 which doesn't do more than looking up a user in a 
file. I don't know what can go wrong with that, but obviously it happens 
from time to time.

It set

poptimeout: 1

but it didn't solve the problem. Is it possible to set a lower timeout?

Regards
Marten
