Hello everybody, I recently contacted contabo to upgrade my VPS and they did, as soon the upgrade took effect, email forwarding stopped working.
Forwarding to gmail doesnt work, Even Internal email forwarding doesn’t work, I used sogo UI to set the forward rule.
This is the error I am getting:
lmtp(email@example.com)<1372><eMCxKX2UfWRcBQAAEZdznQ>: sieve: msgid=CANcrvUSdAC2uSJheccn9xTavzmFaEf8mxsevH6168w5w+ONXfirstname.lastname@example.org: redirect action: failed to redirect message to email@example.com: smtp(postfix:588): RCPT TO failed: 554 5.7.1 <mailcowdockerized-dovecot-mailcow-1.mailcowdockerized_mailcow-network[172.22.1.250]>: Client host rejected: Access denied (permanent failure)
I suspect it happens maybe because they rebooted the VPS, if so is there anything I should check? obviously I did contact them, but they are not helpful.
