About 20 years ago I was able to register IP addresses of our designated mail forwarding servers at SpamCop (via mail to deput...@admin.spamcop.net), so that they would not get listed, and we don't receive reports for those. This still seems to be active today.
Unfortunately I have not been able to update this registration since SpamCop introduced the Mailhost configuration somewhere around 2013. Looks like nowadays every recipient has to add the forwarding servers manually. -- Thomas Mechtersheimer CSL Computer Service Langenbach GmbH Hansaallee 191-193 40549 Düsseldorf Telefon: +49 (211) 8 67 67-0 Telefax: +49 (211) 8 67 67-10 mailto: thomas.mechtershei...@csl.de CSL wird 50 - was Kunden sagen: https://csl.de Geschäftsführer: Renate Altmann-Spangenberg Amtsgericht Düsseldorf HRB 34900 _______________________________________________ mailop mailing list mailop@mailop.org https://list.mailop.org/listinfo/mailop
