Diff of files modified for proposed change
I was advised to post the proposed change here.
I was chatting to our mail admin the other day and he commented on the fact
that you couldnt specify more than one av_scanner in exim, for failovers/load
sharing etc. I decided to take a look at the source of Exim and see if I could
sort that out for him. He suggested that I submit it for possible inclusion in
a future release of Exim. Detailed below is a summary of the changes I've made
and attached is the relevant diff of the source files I've modified.
/* Allows specifying multiple av_scanners seperated by ;
eg. av_scanner = clamd:address port; clamd:address2 port2
if av_random is set to 1, then an av_scanner will be randomly picked rotating
the virus scanning between machines and failing over to another server if one
is down
if av_random is set to 0, then it will always use the first av_scanner
specified
and fail over to the next av_scanner in the list should the first be down. */
I'm not sure if anyone else will find this useful, but I thought I'd share it
anyways. Its been a long time since I've coded in c so the code might need a
little cleaning up. But I've tested it on an Ubuntu install and it seems to
work quite well without any noticable additional overhead.
