i have a question regarding the email setting of a domain...

if i disable the antispam support, does that means that all the email from that domain, will straight go to inbox, and not reach the spam folder...

the reason being is that, i have a customer that uses pop3.. lately, all the regular email such as notification from bank, will go into the spam folder. so when they check offline using pop, they will not get it as it only check the inbox folder...

or any idea on how to overcome this..

thanks..

If it's the only user on that server, here is exim.conf that will just add [SPAM] in Subject and not move mails to Spam folder:
