Hi, folks,

     I'm trying to interpret some results from an SIEM regarding our Exim
servers and am having difficulty. The SIEM claims that ports 587 and 465
are generating traffic on a high-numbered port. I think it's seeing
artifacts from failed authentications and, in about two-thirds of the
cases, I can line the authentication attempts up with that traffic.


     That leaves the other third, which show no sign of authentications in
the logs.


     I'm grasping at straws here, I suppose, but I'm wondering: How
reliable is exim logging on a not-very-busy machine? Pretty reliable, I
figure, but these results make me wonder.


Thanks,

     John A
