Where to find your mail servers 

If your email is hosted on the Papaki 2.0 control panel: 

• Incoming mail server: mail-gr.securemail.pro 
• Outgoing mail server: smtp-gr.securemail.pro 

If hosted on the Plesk environment: 

• Find the server's name in the browser's address bar when logged into Plesk 
• Do not include the port :8443

Additional configuration notes 

• Recommended secure ports:
  • IMAP: 993 
  • POP: 995 
  • SMTP: 465 
  • Use either Encrypted password or Normal password 

• If secure ports are not available:
  • IMAP: 143 
  • POP: 110 
  • SMTP: 25 or 587 
  • Use STARTTLS and Encrypted password (mandatory) 

This ensures that your password is not transmitted in plain text, even on non-encrypted connections.

Additional tips 

• If you’ve recently changed your domain’s nameservers, full email functionality may take 4 to 48 hours to activate. 
• You can test access by logging in via
  • webmail.yourdomain.tld if hosted on the Plesk environment (Papaki 1.0) 
  • webmail.papaki.com if hosted on the new Papaki 2.0 control panel) 

If it works there but not in Thunderbird, the issue is likely with client configuration.
