The version of sendmail was not the issue - the configuration was. This lets us know if things have been altered outside the norm (TLS added ? strange behaviours that we should be aware of that may have impact ?) If the sendmail packages have been updated and the config was changed then generally - the new config will be saved under a different name and you will still be using your older and altered config. - hence the question refering to the confguration NOT the sendmail binary itself. > All other clients work with Outlook.

While it is easy to point the finger and cry "virus", in many cases this is not the case and can end up with unresolved problems. These are still outstanding. > what services pack/OS is on the machine ? > does it work with different clients (OE, Eudora, pegasus mail ?) > what happens when spam filtering is not enabled ? > What do the reject messages say ? > does [domain resolving] ? do other peoples ? Servicepack and OS of the machine (and last time she ran windows updates and what it updated) may be entirely relevant (see the TLS issues above) The different clients are also relevant as this tells us if the problem appears to be related to things othe than the mail seerver itself (the symptoms may not always point directly to the problem) Is the problem with the spam filtering ? remove the complexity and see if this fixes the problem and you can narrow down the things you need to check. Reject messages are vitally imortant as these actualyl give us something real to work with when trying to fix the problem and domain resolving may also point to possible broken things that are easily overlooked. We dont mind helping, but please help us to help you otherwise all we can offer are opinions based on something other than fact. -- Steve. -- redhat-list mailing list unsubscribe mailto:redhat-list-request@xxxxxxxxxx?subject=unsubscribe https://www.redhat.com/mailman/listinfo/redhat-list
