I do not know which action I want to prevent. :) I just want that a letter that comes from the matching host will be simply delivered to its recipient. > Show relevant logging. If it is indeed amavisd-new where the mail is For now I can not show the logging - as they have ceased to send us email, if we are unable to receive it. If farther email arrives I will post its logging here. But for now, to prevent such a situation in the future w/ some other host, may, could You share which steps are undertaken to deliver email from such problematic (not possible to check a host name) hosts? Are the steps I have undertaken in previous posts enough for that, or I miss something and have to dig the problem any farther? If yes, then what are the missing steps? > rejected (or quarantined for having spammy qualities), then you > probably need to route mail from 1.2.3.4 through a separate 'policy > bank' within amavisd-new where spam checks are perhaps disabled.
