7.16 logging email not sent immediately after boot

I sent the following to support@mikrotik.com - will update if I get a response.

Hello Mikrotik,

Logging to email for “critical” topics is broken since 7.16 - it worked in 7.15.3.
I have this issue on all of my devices hAPac^2, hAPac^3, Metal52ac, and RB750Gr3.
I’ve reset my RB750Gr3 to the default configuration, then enabled the bare minimum to reproduce the issue.
/system logging action
add email-start-tls=yes email-to=mikrotik@mailinator.com name=email target=email
/system logging
add action=email topics=critical
/system ntp client
set enabled=yes
/system ntp client servers
add address=ca.pool.ntp.org
/tool e-mail
set from=mikrotik073@gmail.com port=465 server=smtp.gmail.com tls=yes user=mikrotik073
With this configuration, on 7.15.3, at boot there would be a “system, critical, info” log about the ntp time change showing in the memory buffer. An email would also be sent, and this action was logged in the memory buffer as well.

After updating to either 7.16 or 7.16.1, the email is no longer sent and the memory buffer does not show any attempt to send the email.

In the 7.16.1 config I added a new logging action to email all “info” and “!e-mail” events.
/system logging
add action=email topics=info,!e-mail
On reboot, the memory buffer does show attempts to send email for “info” events, but it does not show any attempt to email for “critical” events.

Attached to this email are archives with supout.rif, .backup files and screenshots of the memory buffer log for both the working 7.15.3 config and the not working 7.16.1 config. FYI, The gmail account the router is sending from was generated specifically for this test - I’m not worried about security if you extract the password for it from the backups.

Cheers,
Dave N.
