I try to check the sending of email from R using the mailR package, but I keep getting an error message that I don’t understand. I looked if there is an existing solution, but did not find it.
I also tested starting the same smtp host with port = 25 via telnet, and the connection to the smtp server looked great through telnet. So the port and smtp host does not seem to be a problem. It only becomes a problem when I run through R for some reason. Can anyone help interpret the error here? I really appreciate it.
Command:
send.mail(from = " abc@company.com ", to = " xyz@company.com ", subject = "Hello this is a testing message", body = "And this is a body text", smtp = list(host.name = "mailhub.company.com",port=25), authenticate = FALSE, send = TRUE,debug=TRUE)
Error:

Further debugging shows:

But I can’t understand why sendin email for the designated smtp host does not work correctly as long as the port and smtp information is correct.
