Greetings, I have Magento 126.96.36.199 CE.
Precisely from today's midnight neither my customers nor I receive transactional emails. Until yesterday everything was ok, starting from today everything seems broken.
Few emails [3 / 10] arrive with a 2 hour delay. The other ones look like won't ever arrive.
Any third party extension?
Confirmed all other emails from Magento and server?
Try removing queuing of emails.
@simone_romeo you can refer the below link to check if your emails are there in queue.
You can also download the extension suggested by @Vimal Kumar and then you can check the cron status.
Also check the logs if there you get any clue.
thank you for your answers.
1) Yes, I have a third party extention called SMTP Pro, but it's disabled and I never used it.
2) In my database, cron_email_queue and cron_email_queue_recipients are empty. If I make a new order I see that both of them get an entry with the email that has to be sent.
Edit: after 30 mins about, the entries in these tables are still there and emails are not sent.
@simone_romeo can you take a backup of cron_schedule table and after that truncate it and check if it is repopulated.
