The OP started by saying "there are ways to limit the level of archive that will be scanned as well as the size of the entities to be scanned", which are performance optimizing options one can use if desired. To which I commented that it's not about a message that can't be scanned, but whether your limits allow it to be scanned. Remove the limits, and everything is scanned (presumbly only limited by hardware resources).

[Clamav-users] is there a way of telling when a particular signature was added to the db?
When an email is let through and it is later determined that it did contain a virus, I would like to be able to say "the signature for the virus was added in db version so-and-so", which was active as of so-and-so. Now, the latter I can do, but where can I retrieve the info about when (or in which db-version) the signature was added? (using an API of course). thanks. /Per Jessen, Zürich ___ http://lurker.clamav.net/list/clamav-users.html

[Clamav-users] submit-to-publish time much too long for phishing
This is not really complaint, perhaps just an observation. On 25/11 around 1000CET I submitted a sample and again on 26/11 also around 1000 I submitted a second sample - both phishing. I've only just today around 1800CET received confirmation for both. This is respectively about 56 and 32 hours later. I understand it was on a weekend etc., but for ClamAVs phishing detection/protection to have any meaning/reason at all, the time from submit to publish needs to be a LOT shorter. /Per Jessen, Zürich ___ Help us build a comprehensive ClamAV guide: visit http://wiki.clamav.net http://lurker.clamav.net/list/clamav-users.html

If you're purely using it for your own personal protection, you're absolutely right. If you're using it as a service to others, whether employees or clients, it's a different story. My point is - when I've told someone I can protect them from phishing to some degree, ClamAV is letting me down by not delivering in time. I'd really like to repeat - I am most definitely NOT complaining. I just think the phishing detection of ClamAV is pointless when it's one to two days late. >>> Given the ease with which these can be defeated with other simple >>> tools available to any good messaging server >> >> I could do with a couple of pointers (for server-based use). > > The tools to create your own pattern files are included with ClamAV.
