Pkg exim4 users - Dec 2008 - How to increase connection timeouts

Hi,

I am using Exim4 heavy with clamav. I am experiencing panics with exim4 
timing out while waiting for clamd to finish, I believe. Here are some 
example entries from my paniclog:

2008-12-24 10:20:31 1LFXLY-0001nJ-55 malware acl condition: clamd: unable to
read from socket (Connection timed out)
2008-12-24 11:01:32 1LFXzU-0002Bf-Rp malware acl condition: clamd: unable to
read from socket (Connection timed out)
2008-12-24 11:24:36 1LFYKo-0002QP-72 malware acl condition: clamd: unable to
read from socket (Connection timed out)

The machine is an older machine, however, the volume and load is relatively 
low. My question is how to increase the timeout value for exim4 to wait? Or, 
am I looking at the wrong tree.

TIA
Clarence

Hello,

after a quick look into the docs I do not think this is configurable.
Common clauses of clamd timeouts are:

* running the AV scanner for all mail without size limitation.
* old versions of clamav block for a minute or more when the
  signatures are updated. IIRC the version in etch suffers from this.
  - Upgrading to clamav from volatile helps a lot.
