Hey folks, We are having some delivery troubles with some IPs to sapo.pt destination, their abuse@ and postmaster@ are not responding so far. Any idea or contact in mind that could help ?
451-Connection temporarily refused, if it persists contact your ISP 451-If your IP is a dynamic one (ADSL or dial-up, for instance) please reconfigure your outgoing settings to use your ISP server 451- -- 451-Ligacao temporariamente recusada, se o problema persistir contacte o seu fornecedor de servico 451 Se acede a partir de um IP dinamico (ADSL ou dial-up, p.e.) por favor configure o envio para utilizar o seu ISP (#4.7.0) Thanks in advance ! Simon, from Sendinblue
