Cant sent email with Prestashop 1.75

[presta175]

Have read all possible posts i could find in internet about it.. But still cant find a sollution...

• website: www.digitfort.gr (made tries and in test.dfo.gr - same server)
• Theme: warehouse
• Prestashop version 1.75
• Php 7.0
• Have installed the module "mailalert".
• Languages only Greek enabled (In test subdomain - tried with only english default enabled too)

Tried to make test with PHP and with SMTP. After test email, with PHP it tells me it sents it (but no email ever arrives) and with SMTP enabled, it tells me "Connection could not be established with host smtp.gmail.com [Connection refused #111]"

Have tried with all SMTP variants (SSL, TLS)

I've used a google account (old one and a new one for test) with two verification disabled and "Allow Low Security Devices" , SMTP Enabled too...

 

I'm running out of ideas... Any help ?

Does the Prestashop default email address (which you set up in backoffice) belong to the domain digitfort.gr?

Where do you find the "default email address" ? In parameters, contact ? If yes, yes it is the same domain   ([email protected])

Our emails ( [email protected]) are being sent/received from google servers. Is this connected ?

Is the Mail alerts module installed and enabled?

As for the Google SMTP, depending on your hosting setup you might need to set the hosting email to relay mails through Google
