postfix max email size

[40esp]

I cannot send over 10MB of files in one email with postfix. I've even tried setting the message size through webmin to 20MB.

I need some help with getting it to send over 10MB.

My config file is attached.

I'm running an oldr rev postfix. The only limit I see that looks relevant is the
main.cf.default:message_size_limit = 10240000
which you seem to have changed to 20MB.

Did you restart the service after changing the config file ?
Did you check the logs to see where the problem was (perhaps the destination rejected it for size).
There is an mbox size limit too ,but it's unlikely you hit that.

I find that 10 mb is large for a singe email and would suspect many servers might reject it based on size, at least if it's an ISP for residential customers.

Also, don't use mbox unless you have to especially if you deal in files that large :p

let me be more help...
#tail -f -n 60 /var/log/postix

Then send the file and watch it real time and see what's up :p
