[Help] email notifications with local smtp server not working in TOS 7 [SOLVED]

We kindly request that you send me the "Administrator's email" and "Added recipient email" via forum PM (just click "Contact:" below my username). We'll take a look on our server end.

Hi,

Thank you. I will send the requested details via private message.

Just to add a technical note: the issue is reproducible immediately when clicking “Send test email,” and it started only after upgrading from TOS 6 to TOS 7. On TOS 6 the same configuration was working correctly. The error is visible in the screenshot attached to my first post.
Since DNS resolution and Internet connectivity on TOS are both working, I suspect the problem may be related to the SMTP test path or to the local mail service initialization after the upgrade.
Also, the examples about Gmail, “mail from machines,” and even the anecdote about a recipient mailbox being full may be interesting in general, but they do not seem relevant to my case.

Please let me know if there are any additional logs, diagnostic files, or specific checks you would like me to provide.

Best regards,

Enrico

Sorry — even with the details you gave us, we still can't pinpoint the cause. If you're available tomorrow, you could reach out to Live Chat to book a remote session with our engineer (assuming you're on Italian time). Just make sure to include the link to this thread and your forum name when you do.

Thanks, I need a moment to organize myself since your time zone isn’t very convenient for me, but I’ll definitely follow your advice!

Hi,

This morning your support team fixed the issue with my NAS. The problem was the libsignnas.so file, which had not been updated during the upgrade to TOS 7. The correct version was copied, and now the local SMTP is working again.

Thank you very much for your support!

This fix will be implemented in a future release of TOS7.

Top! Thx again for support! I hope this also helps, and above all, to avoid underestimating the problems highlighted by users, as has been done by other support staff in this forum
