Sending Email via S7-1200 Using TMAIL_C Without SSL

roberto.zeni Experienced Member Joined: 4/9/2009 Last visit: 12/15/2025 Posts: 71 Rating: (1)	Hello, I would like to send an email using an S7-1200 PLC. I only have access to an email account without SSL (using port 587 or 25). Is it possible to use the TMAIL_C instruction without loading any certificates, simply using the SMTP server with the corresponding password? Thank you in advance for your help!
