Received domain MTA option

Received header line MTA options:  (string)
The  MTA option sets the domain name for the  SMTP server  to  use when constructing Received: header lines (and Date-Warning: header  lines). By default, the offical host name of the  local channel is used,. Note that this MTA option does not apply to the Received: header lines generated by other channels; in particular, it does not apply to Received: header  lines resulting from a pass through an intermediate channel (such as a  process, reprocess, or  conversion channel). In such cases, the channel official host name---suffixed with the official host name for the local  channel, in the case of short form names---will be used.

If there is no   set, then   is also  the value that a  Sieve  environment " " will  return. (If neither   nor    is set,  then the MTA falls back to the L channel&#x27;s  official host name.)
