Description

Considering https://tools.ietf.org/html/rfc1891 and http://www.sendmail.org/~ca/email/dsn.html

TD;DR
SMTP session via Telnet:
R: 220 Pure-Heart.ORG SMTP server here S: EHLO Pure-Heart.ORG R: 250-Pure-Heart.ORG R: 250-DSN R: 250 SIZE S: MAIL FROM:<Alice@Pure-Heart.ORG> RET=HDRS ENVID=QQ314159 R: 250 <Alice@Pure-Heart.ORG> sender ok S: RCPT TO:<Bob@Big-Bucks.COM> NOTIFY=SUCCESS,DELAY ORCPT=rfc822;Bob@Big-Bucks.COM R: 250 <Bob@Big-Bucks.COM> recipient ok S: RCPT TO:<Carol@Ivory.EDU> NOTIFY=FAILURE ORCPT=rfc822;Carol@Ivory.EDU R: 250 <Carol@Ivory.EDU> recipient ok S: RCPT TO:<Dana@Ivory.EDU> NOTIFY=SUCCESS,FAILURE ORCPT=rfc822;Dana@Ivory.EDU R: 250 <Eric@Bombs.AF.MIL> recipient ok S: RCPT TO:<Fred@Bombs.AF.MIL> NOTIFY=NEVER R: 250 <Fred@Bombs.AF.MIL> recipient ok

Now Net::SMTP#rcptto looks like this:
def rcptto(to_addr) if $SAFE > 0 raise SecurityError, 'tainted to_addr' if to_addr.tainted? end getok("RCPT TO:<#{to_addr}>") end

It's impossible to use SMTP Service Extension for Delivery Status Notifications in current implementation?

UPDATED: Maybe it's Postfix's job (http://marc.info/?l=postfix-users&m=139333445015239&w=2 and http://www.postfix.org/postconf.5.html). This issue can be closed I guess
