I want to send notification emails to a local email server. The following test failed: ```auto barsch@machine ~ $ kopia notification profile configure email \ --profile-name=email \ --smtp-server=127.0.0.1 \ --smtp-port=25 \ --mail-from=noreply@xxx.yy \ --mail-to=admin@xxx.yy \ --format=txt \ --send-test-notification Sending test notification to SMTP server: "127.0.0.1", Mail from: "noreply@xxx.yy" Mail to: "admin@xxx.yy" Format: "txt" ERROR unable to send test notification: unable to send notification message: tls: failed to verify certificate: x509: cannot validate certificate for 127.0.0.1 because it doesn't contain any IP SANs ``` Sending emails per shell is working, e.g. ```auto barsch@machine ~ $ echo "This is a test." | mail -s "Test" barsch@xxx.yy ``` Any ideas? ---

> [@barsch](#): > > `cannot validate certificate for 127.0.0.1 because it doesn't contain any IP SANs` This is not really kopia issues but your SMTP certificate problem. Looks like kopia does it right and requires server to be configured properly. To validate the certificate successfully the IP must be given inside the subject alternative names section. When you create your certs: 1. Edit your `/etc/ssl/openssl.cnf` - add `subjectAltName = IP:127.0.0.1` in `[v3_ca]` section. 2. Recreate the certificate You will also find tones of sources on google how to create proper certs. ---

no - port 25 above means I want to connect via plain unencrypted SMTP service (configured as send only to smarthost) which does not require a certificate - one can test this with a simple telnet client, e.g.: ```auto barsch@machine ~ $ telnet 127.0.0.1 25 Trying 127.0.0.1... Connected to 127.0.0.1. Escape character is '^]'. 220 machine ESMTP Exim 4.96 Sat, 14 Dec 2024 00:30:00 +0000 EHLO xxx.yy 250-machine Hello localhost [127.0.0.1] 250-SIZE 52428800 250-8BITMIME 250-PIPELINING 250-PIPECONNECT 250-CHUNKING 250-STARTTLS 250-PRDR 250 HELP MAIL FROM:noreply@xxx.yy 250 OK RCPT TO:admin@xxx.yy 250 Accepted DATA 354 Enter message, ending with "." on a line by itself Subject: Test This is a test. . 250 OK id=1tMG3n-0020gr-2R QUIT 221 machine closing connection Connection closed by foreign host. barsch@machine ~ $ ``` So it seems Kopia does not to support unencrypted SMTP, or? ---

Unfortunately I am also realizing that Kopia notification email authentication is limited and only supports SSL, and has no other options. In my case I got this error when sending to port 587 (which requires SMTP authentication username and password) _ERROR unable to send notification message: tls: failed to verify certificate: x509: certificate signed by unknown authority_ Just when I discover that Kopia now has email notifications I get disappointed that I cant use it since we have an internal LAN mail server that use SSL for internal communications ☹ ---

Hey same problem here!

Same situation. send email with internal smtp server on port 25 with no security give error. I have made a python script that expose webhook api, takes the message via post/get and in script can configure the SMTP server externally as a relay. A raw fix …waiting kopia decide to accept insecure connections in notifications it’s a beta code but soon I could publish it or attach it here if possible ---
