Smarthost settings for Exim in ispmanager 6

By default, the Exim configuration in ispmanager 6 doesn't contain any standard settings for connecting to smarthost. To connect to smarthost in this situation, edit the configuration file.

Add the following lines to the very beginning of the configuration file:

UPEX4CmacrosUPEX4C = 1
# ROUTER_SMARTHOST=MAIL.HOSTNAME.FOR.CENTRAL.SERVER.EXAMPLE

The second line must be uncommented if the address of an existing smarthost server is specified.

At the beginning of the begin routers section, add the following lines, replacing the dnslookup: block:

.ifdef ROUTER_SMARTHOST
  smarthost:
    driver = manualroute
    domains = !+local_domains
    transport = smarthost_smtp
    route_data = ROUTER_SMARTHOST
    ignore_target_hosts = <; 0.0.0.0 ; 127.0.0.0/8 ; ::1
    no_more
.else
  dnslookup:
    driver = dnslookup
    domains = !+dummy_domains : !+local_domains
    transport = remote_smtp
    ignore_target_hosts = 0.0.0.0 : 127.0.0.0/8
    self = pass
    no_more
.endif

If you previously modified the parameters in the dnslookup: block, save them for the new block.

At the beginning of the begin transports section, add the following lines:

smarthost_smtp:
  driver = smtp
  message_size_limit = ${if > {$max_received_linelength}{998} {1}{0}}
  multi_domain
.ifdef _HAVE_TLS
  hosts_require_tls = *
  tls_verify_hosts = *
  tls_try_verify_hosts = *
  tls_sni = ROUTER_SMARTHOST
.ifdef _HAVE_OPENSSL
  tls_require_ciphers = HIGH:!aNULL:@STRENGTH
.endif
.ifdef _HAVE_GNUTLS
  tls_require_ciphers = SECURE192:-VERS-SSL3.0:-VERS-TLS1.0:-VERS-TLS1.1
.endif
.endif
.ifdef _HAVE_PRDR
  hosts_try_prdr = *
.endif

After making the changes, begin configuring a specific smarthost for Exim.
