        I have a server running centos-release-7-2.1511.el7.centos.2.10.x86_64
with dovecot version 2.2.10.  I am also using roundcube for webmail.
when a vacation filter (reply with message) is created in roundcube it
adds a rule to managesieve.sieve in the user's mailbox.  everything
works fine except the reply comes from vmail@ns1.domain.tld instead of
user@domain.tld.  ns1.domain.tld is the fully qualified name of the server.
it used to work fine on my old CentOS 6 server so I am not sure what has changed. Can anyone point me in the direction of where I can configure this behaviour?
