In the exim configuration file, routers section, X-AntiAbuse headers are added to the outgoing email.
Is there an UI option for turning those off? I tried re-writing the routers section in advanced exim configuration but that is not allowed (i.e. duplicate router name error). The only way seems to be manually editing the exim.conf and commenting out the lines from each router description which is over written during update 
Code:
headers_add = "${perl{mailtrapheaders}}"
