It hosts some Mailing Lists with Mailman3 and can do that much volume sometimes whenever there is a discussion. My VPS provider noticed this volume and warned me that I was exceeding the limits, and they suspected that I was a source of spam or something, I explained myself and answered all their questions clearly and technically and they lifted the limits. I have DKIM signing and SPF/DMARC DNS records. The VPS provider is CONTABO, if that matters. -- Best regards, Odhiambo WASHINGTON, Nairobi,KE +254 7 3200 0004/+254 7 2274 3223 In an Internet failure case, the #1 suspect is a constant: DNS.
