Many thanks, did all recommended steps and issue is solved: - defined Identity in the DKIM-selector definition at dkimconfig.txt - updated Mail::DKIM - updated assp - updated perl

The latest version of Mail::DKIM should add an '@' in front of the domainname/hostname! make sure Mail::DKIM is uptodate (latest version 1.20200513.1) if the problem still exists, define the Identity in the DKIM-selector definition (a general recommendation to avoid identity missmatches). Notice: older Mail::DKIM version may not support this setting. Identity=EMAILADDRESS or Identity=@DOMAIN - assp is outdated - perl is outdated Thomas Von: "Thomas Kofler" <k...@outlook.com> An: "assp-user@lists.sourceforge.net" <assp-user@lists.sourceforge.net> Datum: 20.08.2020 21:13 Betreff: [Assp-user] DKIM: Validating Signature, Details: bad identity ASSP version 2.6.3 *SPAM-Evaporator* build 19169, perl-5.16.3-292.el7.x86_64, CentOS 7 x64 Hi, DKIM signatures are attached but are shown as Validating Signature result = invalid Details: bad identity when verified (tho...@domain123.com ==> a6icpijhjr5...@dkimvalidator.com) Also ASSP comes to the same result: Aug-20-20 20:43:08 m1-48988-06675 [Worker_1] [MessageOK] 192.168.2.20 <tho...@domain123.com> to: a6icpijhjr5...@dkimvalidator.com message ok [1] -> notspam/1--2823069.eml Aug-20-20 20:43:08 [Worker_1] DKIM: Selector = key1 Aug-20-20 20:43:08 [Worker_1] DKIM: Domain = domain123.com Aug-20-20 20:43:08 [Worker_1] DKIM: KeyFile = /opt/assp/certs/dkim-private.key Aug-20-20 20:43:08 [Worker_1] DKIM: Method = relaxed/relaxed Aug-20-20 20:43:08 [Worker_1] DKIM: Headers = Message-ID:From:Subject:To:MIME-Version:Content-Type Aug-20-20 20:43:08 [Worker_1] DKIM: Mode = DKIM Aug-20-20 20:43:08 [Worker_1] DKIM: Domain = domain123.com Aug-20-20 20:43:08 [Worker_1] DKIM: KeyFile = /opt/assp/certs/dkim-private.key Aug-20-20 20:43:08 [Worker_1] DKIM: Method = relaxed/relaxed Aug-20-20 20:43:08 [Worker_1] DKIM: Headers = Message-ID:From:Subject:To:MIME-Version:Content-Type Aug-20-20 20:43:08 [Worker_1] DKIM: Mode = DKIM Aug-20-20 20:43:08 [Worker_1] DKIM: Algorithm = rsa-sha1 Aug-20-20 20:43:08 m1-48988-06675 [Worker_1] 192.168.2.20 <tho...@domain123.com> to: a6icpijhjr5...@dkimvalidator.com info: successfully added DKIM-Signature Aug-20-20 20:43:08 m1-48988-06675 [Worker_1] 192.168.2.20 <tho...@domain123.com> to: a6icpijhjr5...@dkimvalidator.com DKIM: self signature check: result: invalid - detail: invalid (bad identity) DKIM-Signature: v=1; a=rsa-sha1; c=relaxed/relaxed; d=domain123.com; h= Message-ID:From:Subject:To:MIME-Version:Content-Type; s=key1; i= www12.hosting.cc; bh=yozb3+jTZHJZWY6+yAc67TjplMM=; b=f/PePz5s6q0z EGEGFxPJ9H6jCI7bQ+sT+hGF/Fh1KSpXKMSxMvSO3lXp4KCdjkL4UKllR/NzEBrS v00DehJ652IJYOF4orwpuDX2qZ6l2hqdNKK+4eMoqXXRP8gnsgAEpk91N5D8ql6O DSwZ36EWVoIkmaHnWYOZPcnKjgn8Xek= I suppose its the i tag which is causing the issue? www12.hosting.cc is an alias of the machine on which assp is running, but not the external DNS name. Shouldln't it be something like i=domain123.com (the sending mail domain?)
