Hello. I'm using ISPC 3.1 for years now, already bought manual few times (and i would buy once again if there would be version for ISPC 3.2). My old ISPC 3.1 server (on CentOS 7) is rock stable, i know everything and all problems that may appear. Now i've setup new server, with fresh install of Debian 11 (as it is recommended distro for ISPC), and fresh install od ISPConfig 3.2 using autoinstaller (where i found one error: https://git.ispconfig.org/ispconfig/ispconfig-autoinstaller/-/issues/74 ). Today i finally setup firewall settings, added some websites and find out problem when trying to add email. What i've done was - add new email domain (DNS records are already configured outside) - add new email account (genereated new DKIM) - sent email for testing (using this site: mail-tester.com ). It find out DKIM problem. So at first moment my idea was that i've done some problem when copy/past keys, so i regenerated it, checked twice. Still problem (with new DKIM). The message on the testing site was that DKIM key lenght is unknown that was a hint for me, that it must be problem with DNS record (i'm using cloudflare, got like 50 domains there, and i never had any problems with DKIM). So i comapred what is on the ISPC panel with data inside file and it appeared that there are differences. My domain name is marcinwilk.eu, here is what ISPC shows to add for DKIM DNS record: And here is what is inside file: # cat /var/lib/amavis/dkim/marcinwilk.eu.public -----BEGIN PUBLIC KEY----- MIIBIjANBgkqhkiG9w0BAQEFAAOCAQ8AMIIBCgKCAQEAlW+ocwBLPgpBulZf0CRB 70/1+6kv3mEFY5raNd5u6YfRg1O03TCWfYMTF7ih3S5p3Oaa5k4dBkEOl9vXgV/x MqfBaFkfpUg2+8swiBltWAzyw7JyrZZuU0m/uvI5ZW5JG6TSZsUmpAh0zRJkDATP Ux6H6cmW5rVaIalUDcoG5webLFpKCOekCeJkgJAz6hD5aM2st3lsue4JPKkLZG8j XcNPiJCg4AYAaggYAAeyA3f9oR53PzF6pNEfTwp+uKSG24aPDGQGKgnzdRVpAij1 +wAK+OQ8HA2VlqrMbd5JZzLr6SHjWHO2oVW8bDwMdcsoJIn6UkaF7opB3SSZvNqs hwIDAQAB -----END PUBLIC KEY-----I do not know where can be problem. I was trying to change key lenght to 1024 bits and regenerate it, but it didn't resolved problem. Regenerating keys also didn't help. I believe there must be some error inside ISPC (as i didn't configured anything manually). I would also want to know if there are 3 things implemented in ISPC 3.2: - Postfix SNI support? - Whitelisting from RBL checks? - Limiting users sending mail in specific period of time? Thanks for any response.
That seems to match the public dns key: Code: $ host -t txt default._domainkey.marcinwilk.eu default._domainkey.marcinwilk.eu descriptive text "v=DKIM1; t=s; p=MIIBIjANBgkqhkiG9w0BAQEFAAOCAQ8AMIIBCgKCAQEAlW+ocwBLPgpBulZf0CRB70/1+6kv3mEFY5raNd5u6YfRg1O03TCWfYMTF7ih3S5p3Oaa5k4dBkEOl9vXgV/xMqfBaFkfpUg2+8swiBltWAzyw7JyrZZuU0m/uvI5ZW5JG6TSZsUmpAh0zRJkDATPUx6H6cmW5rVaIalUDcoG5webLFpKCOekCeJkgJAz6hD5aM2" "st3lsue4JPKkLZG8jXcNPiJCg4AYAaggYAAeyA3f9oR53PzF6pNEfTwp+uKSG24aPDGQGKgnzdRVpAij1+wAK+OQ8HA2VlqrMbd5JZzLr6SHjWHO2oVW8bDwMdcsoJIn6UkaF7opB3SSZvNqshwIDAQAB" No. You can configure it manually if you wanted. No. I use postscreen for my up-front rbl's, including white and black lists, but that must be configured manually. Likewise any whitelists in your spam scanner (other than default configuration) would need configured by you. No. I use postfwd for time based rate limits, which is pretty close (just set the limit to 0), but nothing in ISPConfig configures this.
Yes. I made correct DNS record when i identified problem. I want my email to work Thank You for all answers. Now i know where i'm at with new version
