Hello Eximers,
(I guess this is a good name, no?)
I've had a request from a user and I believe it's practical. I know I can run
a router just before the local delivery to do it, since Exim is able to know
the $message_size. What I don't know is how to write the router :)
Two users have asked me to block any mail sent to them that is surpasses some
$message_size. One of them wants all mail over 3MB to be rejected with some
message. The other one prefers 5MB. On my server, the global message)size limit
is 10M, which I believe is stupid for an ISP which has some clients with pretty
good connections.
I know the $message_size is available for the system filter also but I was
wondering if people have recommendations. Looking at the filter specification,
I've noted two possibilities:
if $message_size is above XX
${ if >{$message_size}{4M} .....
The problem is that both users (and some others yet to come) all prefer different
values. I was thinking that I could use a flat file, or some db where I could store
username:$message_size values, like
user1: 3M
user2: 5M
I'd like to do this globally, not via some .forward as maintaining that would be
a pain in the $%*.... MySQL would be a good option but my users are not MySQL based.
These are system accounts.
Any pointers/suggestions most welcome.
Thank you.
