exim question (for exim gurus)

graziano1968 · 01-02-2009, 06:09 AM

Hello

at the top of my exim.conf I am using this

local_interfaces = 127.0.0.1
daemon_smtp_ports = 125

to pass all the email to an antispam proxy (ASSP).

It pass all the email to port 125 .
I would pass to port 125 ONLY email which have 1 or more attachments bigger than 1 MB . Is it possible using an "if" condition ? How ?

Thank you

i do not know how you are passing the message to assp but the condition is

Code:

condition  = ${if >={$message_size}{1000K} {1}}

Thank you . I'm trying this now ...

Code:

condition  = ${if <={$message_size}{1000K} 
{

local_interfaces = 127.0.0.1
daemon_smtp_ports = 125

}
}

however messages bigger than 1000K are still passing to port 125 (ASSP)

The condition is correct but it all depends on where in the config file this condition is being executed.

I have just checked, what you are trying to do is NOT achievable, ASSP is the one accepting the mail on port 25 not exim, it is ASSP that passes the scanned mail to exim.

If exim was listening to port 25 then passing the mail to ASSP your scenario could work.

on cPanel servers , using

local_interfaces = 127.0.0.1
daemon_smtp_ports = 125

at the very top of exim.conf , ASSP works great. No other configuration is possible with cpanel servers.

Now , what I am trying to do , is to pass all attachments greater than 1 MB to exim (without passing to ASSP) and all other email to ASSP .

I put the condition above in the first lines of exim.conf .

Currently I have

email ---> port 25 (ASSP) ---> exim port 125

I would have this

email ---> port 25 (EXIM) ... then

if email greater than 1000KB --> EXIM
if email less than 1000kB --> ASSP > EXIM

Any way to reach this goal ?
