[Pkg-exim4-users] How to run a script before each queue run?

[Eugen Melinte]

Hello,

this is not strictly Debian, but: 

Is there a way to run a script before each queue run or before the SMTP transport connects to the smarthost?

Background info: I am using as smarthost the SMTP server of my ISP. They have just changed the policies on their SMTP servers and now each time my exim connects to the smarthost it gets a "550 Authorization required". This is because now they require POP before SMTP authentication. Which is why I need to run the script _before_ any of those two events (queue run or SMTP connect).

Any advice welcome.

Thanks
a.
