In my absence, someone decided they needed to switch to on-prem ProofPoint appliances, and I guess the software stack or configuration subsequently regressed. FWIW, the "mi.ruhr-uni-bochum.de" MX host of "ruhr-uni-bochum.de" is ECDSA only, and probably not missing much mail. -- Viktor. 🇺🇦 Слава Україні! _______________________________________________ Postfix-users mailing list -- [email protected] To unsubscribe send an email to [email protected]
