sieve sending vacation message from vmail at ns1.domain.tld

[Matthew Broadhead]

I read somewhere it might have something to do with a line in master.cf
dovecot   unix  -       n       n       -       -       pipe
flags=DRhu user=vmail:mail argv=/usr/libexec/dovecot/deliver -d 
${recipient}

i changed it to
flags=DRhu user=vmail:mail argv=/usr/libexec/dovecot/dovecot-lda -f 
${sender} -d ${user}@${nexthop} -a ${original_recipient}

but it made no difference
