It doesn't appear to be a networking issue, pings show no packet loss. Not sure what it could be really. Do you notice a delay before you get the 220 banner ?
I tried with both tls and without, same result: openssl s_client -connect smtp.secureserver.net:25 -starttls smtp CONNECTED(00000004) Didn't find STARTTLS in server response, trying anyway... write:errno=0 --- no peer certificate available --- No client certificate CA names sent --- SSL handshake has read 0 bytes and written 356 bytes Verification: OK --- New, (NONE), Cipher is (NONE) Secure Renegotiation IS NOT supported Compression: NONE Expansion: NONE No ALPN negotiated Early data was not sent Verify return code: 0 (ok) On Wednesday, 14/05/2025 at 10:42 Viktor Dukhovni via mailop wrote: On Wed, May 14, 2025 at 10:15:02AM -0400, Scott Q. via mailop wrote: > Can someone from GoDaddy reach out ?
