relay mailer assumes, that relay is running sendmail and thereofe uses
different kind limits for line length and so on.
(So 'relay' mailer is 'esmtp' mailer + 'smtp8' mailer + bigger line length.)

Use also: define(`confSMTP_MAILER', `esmtp')
(Value of confSMTP_MAILER should be smtp or esmtp.)
Quote from cf/README: --------------------------------------------------------
smtp The Simple Mail Transport Protocol mailer. This does
not hide hosts behind a gateway or another other
such hack; it assumes a world where everyone is
running the name server. This file actually defines
four mailers: "smtp" for regular (old-style) SMTP to
other servers, "esmtp" for extended SMTP to other
servers, "smtp8" to do SMTP to other servers without
converting 8-bit data to MIME (essentially, this is
your statement that you know the other end is 8-bit
clean even if it doesn't say so), and "relay" for
transmission to our RELAY_HOST, LUSER_RELAY, or
MAILER_HUB.
And another quote: -----------------------------------------------------------
confSMTP_MAILER - [smtp] The mailer name used when
SMTP connectivity is required.
One of "smtp", "smtp8", or "esmtp".
