[Exim] Squirrelmail and exim headers

Is anyone else running Exim and Squirrelmail together? I do, and the
return path on all my outgoing email is "apache@???" rather
than "paul@???". If there a setting to correct that?

Squirrelmail 1.4.1
Exim 3.20
Redhat 8

Regards,
Paul

PS: I tried installing Exim 4 but had dependency issues.
