[exim] require verify = sender/callout but if $interface_por…

Hi,

I want to set something here. I have this in my current config:

  require verify          = sender/callout
  accept  domains         = +local_domains
          endpass
          message         = "The recipient can not bla bla."
          verify          = recipient

I want to add something like this: if the interface port is 587, don't use
the callout function. Please help me to join the following stuff in the acl
above.

          condition       = ${if eq{$interface_port}{587}...

and

  require verify          = sender

Awaiting your answers.
