Unfortunately this is not supported by OpenDKIM today, see: https://github.com/trusteddomainproject/OpenDKIM/issues/6
OpenDKIM in this version only supports a single signature (parameter SignatureAlgorithm), eg *either* ‘rsa-sha256’ *or* ‘ed25519-sha256’. ** Bug watch added: github.com/trusteddomainproject/OpenDKIM/issues #6 https://github.com/trusteddomainproject/OpenDKIM/issues/6 -- You received this bug notification because you are a member of Ubuntu Mail Server, which is subscribed to opendkim in Ubuntu. https://bugs.launchpad.net/bugs/1915732 Title: ed25519 signing does not work Status in opendkim package in Ubuntu: New Bug description: Using Ubuntu 20.04 LTS. # apt-cache policy opendkim opendkim: Installed: 2.11.0~beta2-1 Candidate: 2.11.0~beta2-1 Version table: *** 2.11.0~beta2-1 500 500 http://archive.ubuntu.com/ubuntu focal/universe amd64 Packages 100 /var/lib/dpkg/status # opendkim -V opendkim: OpenDKIM Filter v2.11.0 Compiled with OpenSSL 1.1.1f 31 Mar 2020 SMFI_VERSION 0x1000001 libmilter version 1.0.1 Supported signing algorithms: rsa-sha1 rsa-sha256 ed25519-sha256 Supported canonicalization algorithms: relaxed simple Active code options: QUERY_CACHE USE_DB USE_LDAP USE_LUA USE_ODBX USE_UNBOUND _FFR_ATPS _FFR_RBL _FFR_REPLACE_RULES _FFR_SENDER_MACRO _FFR_STATS _FFR_VBR libopendkim 2.11.0: atps query_cache However, when configured to use "MultipleSignatures yes" and two Selectors: opendkim[113250]: 6307460C4C: SSL error:0607907F:digital envelope routines:EVP_PKEY_get0_RSA:expecting an rsa key opendkim[113250]: 6307460C4C: dkim_eom(): resource unavailable: EVP_PKEY_get1_RSA() failed To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/opendkim/+bug/1915732/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-mail-server Post to : [email protected] Unsubscribe : https://launchpad.net/~ubuntu-mail-server More help : https://help.launchpad.net/ListHelp
