OK! In other words, if my Exim has to send a BOUNCE to an address with SRS
hash, it gets the real address from it.
And, if my Exim get an E-Mail for a SRS-rewritten-address (for example a
bounce), it checks if the hash is still valid.
Do I understood what you explained?

This is very strange...
I know that the destination of my forward DO sender verification, but I
didn't see anything with NGREP to check my SRS address...
Do you have an explanation for this strange thing?

Thanks a lot!
