Question

Hello,

i'm trying to setup events reporting via mail on my RUTXR1 with firmware RUTX_R_00.07.02.8 , but somehow it will not accept my mail account. I use the following settings on the RUTXR1 according to the strato server settings (https://www.strato-hosting.co.uk/faq/product/the-strato-email-server/).

Secure Connection:   ON
SMTP Server:            smtp.strato.de
SMTP Port:                465
Credentials:                ON

The server expects SMTP SSL/TLS but RUTXR1 seems to use STARTTLS (excerpt from system log). Is it possible to change the protocol or does anybody know what's the issue here? I searched the web, the manual and this forum but cannot find anything.

Fri Sep 23 20:39:59 2022 daemon.err events_reporting: Failed to send email to "elw@***"
Fri Sep 23 20:40:42 2022 kern.notice kernel: sim_switch configuration has been changed
Fri Sep 23 20:40:42 2022 daemon.err events_reporting:  email to "elw@***"
Fri Sep 23 20:40:42 2022 kern.notice kernel: events_reporting configuration has been changed
Fri Sep 23 20:40:43 2022 daemon.err vuci[3581]: Didn't find STARTTLS in server response, trying anyway...
Fri Sep 23 20:40:43 2022 daemon.err vuci[3581]: write:errno=0
Fri Sep 23 20:40:43 2022 daemon.err vuci[3581]: sendmail: helper exited (1)
 

Thanks a lot for any help or hints!

Best regards,
Philipp

Hello,

Did you have this issue with previous firmware versions.

Also, could you provide a complete troubleshoot file?

Best regards,

Hey,

our device is very new, so I did not use older firmware. I added the troubleshoot file to the original post.

Thanks a lot!

How can i disable STARTTLS? If i use your guide https://wiki.teltonika-networks.com/view/Sending_emails_via_command_line and remove the STARTTLS i can send an email without any issues:
