    exim rety time problem with greylisting

    Hi

    I have a cpanel server with exim. A customer try to send a mail to another server which is using greylisting.

    In exim.conf I have the retry time configured, that during the first 2 hours, eximt should retry every 15min to deliver the mail.

    * * F,2h,15m; G,16h,1h,1.5; F,4d,8h

    But when exim realize, that the other server is often "temporary down", which means the other server gives the error 451 back (greylisting), then exim ignores my retry time which I configured and just wait very long. Here is an example:

    Code:
    2009-09-01 23:20:17 1Miam1-0001jl-JF <= Info@customerdomain.ch H=84-72-143-74.dclient.xxxxxxx.ch ([10.0.1.3]) [84.75.148.74] P=esmtpsa X=TLSv1:AES128-SHA:128 A=fixed_plain:info+xxxxxxxxx.ch S=1124 id=90126716-7D8A-4541-8A43-5AF7B65FD45F@customerdomain.ch T="Konten"

    How can I configure eximt, that it ignores this database and just retry like configured?

    Thanks
    Michael

    I noticed this issue when I was researching exim. At that time (about 2 years ago) the only solution was to modify source and compile for your own use.

    I was suprised and not in a good way
