Hi Eric: One thing I've noticed is that there's a message size limit on what simscan/spamd/clamd will check. Messages over several megabytes are skipped. Is there a config file somewhere controlling that? Jeff On 9/16/2020 2:07 PM, Eric Broch wrote: Hi Jeff, I'm not sure why ClamAV would

Hi Jeff, I'm not sure why ClamAV would miss a virus. Maybe they'd have a better ideal on the ClamAV mailing list. I've never really depended on ClamAV or Spamassassin, though I'd like to, but when killing spam was absolutely necessary I used a third party spam gateway. Eric On 9/16/2020 9

Also, use 'toaststat' or equivalent to make sure all the components of your toaster are up and running. If you don't have enough memory on your box, then ClamAV will sometimes crash, making mail undeliverable and generating the "temporarily rejected" message you've seen. Rebooting will cure th
