[exim] How to set source IP for callout check?

Hi!

Is it possible to specify source interface for callout check?
I set "interface = 213.133.161.33" in smtp transport, it works OK
for outgoing smtp, but has no effect for callout, and sometimes I
get something like this:

Aug 25 09:50:41 happy exim[1413]: H=hermes.ldc.net (mail.volz.ua) [213.160.128.8] sender verify fail for <balya@???>: response to "RCPT TO:<balya@???>" from mail.volz.ua [213.160.128.8] was: 550 5.7.1 Client host rejected: cannot find your hostname, [213.133.164.6]

Mail from me to this email sends OK, from 213.133.161.33:

Exim 4.69.

Please help.
