Cfmail attachment failing at 7Mb


i have app users can upload files attached email message. whenever file size exceeds 7mb in testing, mail fails, goes undelivr directory , mail.log shows:"ioexception while sending message." exception.log shows: "javax.mail.messagingexception: ioexception while sending message; nested exception is: java.net.socketexception: software caused connection abort: socket write error"

the file uploaded , exists specified on cfmailparam tag.

any ideas?


what mail server using. admin on mail server? possible there max limit set on mail server prevent people sending ridiculously large email attachments such this.

when says "software caused connection abort" mail server refusing attachment.

if user can "upload" file, why arent using cffile tag file upload processes?
