Open relay but not an open relay?

[mstuebner]

Hello,

to my surprise I got the following alert message from lfd:

Time: Sat Mar 8 20:34:56 2008
Type: RELAY, Remote IP - 201.141.15.50 (customer-201-141-15-50.cablevision.net.mx)
Count: 101 emails relayed
Blocked: No

Sample of the first 10 emails:.....

what lets me think that this server works as open relay (quite fresh standard installation). A test made by abuse.net makes 10 tests and concludes that this server doesn't relay at all.

Who may I trust more, or what may cause that alter if it isn't an open relay? How to understand this?

Thanx for hints,

Edit: For one of the message IDs listed in the alter exim_mainlog shows the following, what I would understand as a TRY to relay, but without success?

The logs you attach mean that 201.141.15.50 sent two email to two different email addresses on domain.de. If domain.de is a local domain for your server then it is expected behaviour to accept those mail. As for lfd, i don't know the internals of it at the moment to explain why it complains.
