lmtpd memory leak?

[Michael Menge]

Hi,


on this server is are only a few test users and the postmaster account.
The Postmaster account has a very copmlex sievescript which uses regexp.
As fas as i can tell all hanging lmtpd-processes are delivering mails  
to this account. I found the deferred message and could reproduce the  
effect with an delivery retry of this eMail. But i did't find the  
regex which caused the problem yet.

So how can I help to find this bug. I had i look at bugzilla, but  
found nothing
related.

thanks for the help so far
