is there anyone out there who has some experience with the blocking mechanism of Microsofts mail server? We're running a mail server at our company which ends up on their blacklist from time to time and we're wondering if there are some steps we could take in order to prevent this.

You may want to join the mailop mailing list: List-Archive: <https://list.mailop.org/private/mailop/> List-Post: <mailto:mailop@mailop.org> List-Subscribe: <https://list.mailop.org/listinfo/mailop>, <mailto:mailop-request@mailop.org?subject=subscribe> and ask there as it seems more applicable to that list, and is a common topic of discussion there.
