disroot org SMTP server gives "483: Device network error. Please try again."

Hi

The email account is working in Thunderbird with same settings and same password.




This is not an App Password.
It's normal SMTP/TLS Login, I not use Gmail

Is there a log file with more info than this?

Model E Series E340. Latest Firmware (v3.1.0.3382_2404178058)


Thanks

@celina_867750978158811 Try with port = 465 (implicit TLS/SSL). Maybe Reolink cams won't send the STARTTLS. I am not home and so I cannot confirm this.

@celina_867750978158811 your SMTP server address is incomplete. It is missing the host. Try using mail<dot>disroot<dot>org for the SMTP server address.

I tried with port 465 but same error

@chopstix my SMTP server is correct. See

dig +short -t mx disroot org
10 disroot org.

[joseph_1979]

@chopstix IMAP and SMTP addresses is disroot(dot)org

Try port 993.

If she is a bit technical, she can capture a trace using wireshark. Maybe there are more details which Reolink camera is not exposing with the error.

@celina_867750978158811 @joseph_1979 yes, MX query resolves to root domain IP address. Full zone file query does show mail<dot> as an A record that resolves the same IP address. I have found over the years that using a FQDN versus root name only can often times solve issues. It doesn't hurt to try.
