    Yahoo mail sent me this:
    How do I do this?

    Whereabouts do I look for these?
    My problem is... I am not getting bounces. My mail is just ending up in the bulk boxes and not being delivered to the inbox, so all of my customers on Yahoo think I'm ignoring them. I already enabled all of the SPF stuff on cpanel.

    Mail server (MTA) logs are stored in:

    /var/log/exim_mainlog
    /var/log/exim_rejectlog
    /var/log/exim_paniclog

    The paths are slightly different on FreeBSD. /var/log/exim_paniclog should be empty (or nearly empty).

    Thank you.

    I see some very strange stuff in here, like:
    (Anyone know what that means)
    ...and tons of other stuff. Looks as though I have a very popular mail server as there's hundreds and hundreds of attempted spammers trying to use my server.

    The only thing empty was the paniclog.



    Final question: Do these logs ever get erased? I'm able to go to about 2 days ago and it just keeps going and going..

    I couldn't find anything from my legit address to yahoo. I suppose if a message is accepted, it wouldn't show here?

    In the UK, Yahoo seems to run its email system jointly with British Telecom (BT). BT-Yahoo garbles destination email addresses. For example: If you send to <fred.bloggs@branch.myshop.co.uk> they may lose the substring "branch." in the address and attempt delivery to <fred.bloggs@myshop.co.uk> - which may not exist! This has the effect of a "black hole" for branch staff emails from BT-Yahoo users.

    When I reported it, they said I had reported it to the wrong department, but my evidence is that both broadband and dial-up users suffer the same problem anyway. I chased it up yesterday.

    I think they now use DomainKeys, but am not sure whether they yet enforce SPF compliance.

    I presume your rDNS is set up? I did find a hosting company whose users could not send email to many places because the hosting company did not have rDNS set up, and customers had no facility to do their own!!
