Passbolt sends verification with test email option but it doesn´t do that the first time you loggin

Hum, this is interesting:

I think you are facing the issue described in Reason 4 of the FAQ: Passbolt Help | Why are my emails not being sent?

Can you clear the cache ?

sudo -H -u www-data bash -c "/usr/share/php/passbolt/bin/cake cache clear_all"

Cheers,
