G'day folks
This problem has caused me much concern and no matter who I ask,
regardless of exim experience I've been unable to solve it.
In exim's configure file i've specified the following director:
vircheck:
driver = smartuser
transport = virus_scan
condition = "${if or {{eq {$received_protocol}{scanned_ok}} \
{eq {$sender_host_address}{127.0.0.1}}}\
{0}{1}}"
user = root
(never_users=root is commented out, so root should be a valid user)
The corresponding transport is as follows:
virus_scan:
driver = pipe
command = "/usr/sbin/antiv > /dev/null"
user = root
The concept is for any mail for local delivery, not having a received
protocol value of scanned_ok to be piped to an external virus scanning
script - this script will then mark verified mail as scanned_ok and
resubmit it to exim for delivery.
The script executes perfectly from commandline - if I was to have an email
in say /tmp/testmsg, headers and all, and do a manual pipe like this :-
cat /tmp/testmsg | /usr/local/sbin/exim -t -oMr scanned_ok
The script executes perfectly, verifies that there are no viri, ad the
email is submitted for delivery, and arrives at its destination.
However as soon as one tries to get exim to pipe it itself, this error
appears in the exim_mainlog, and the mail disapears. :-

The error email I get contains this:-
jus@???:
Child process of virus_scan transport returned 2 from command:
/usr/sbin/antiv
Yet the script appears to execute perfectly when run from commandline.
Anyone...?
Many thanks in anticipation,
jus
