Sending mail from R failed using sendmailR

Question

I am trying to use the mailR library in R to send mail. This is my code:

install.packages("sendmailR")
library(sendmailR)
sender <- "myemailid@umd.edu"
recipients <- "myemailid@gmail.com"
send.mail(from = sender,
      to = recipients,
      subject = "Subject of the email",
      body = "Body of the email",
      smtp = list(host.name = "exch.mail.umd.edu", port = 465,
                  user.name = "myemailid@umd.edu",            
                  passwd = "mypassword", ssl = TRUE),
      authenticate = TRUE,
      send = TRUE)

This code is giving me the following error:

org.apache.commons.mail.EmailException: Sending the email to the following server failed : exch.mail.umd.edu:465

I am not able to get the reason behind this error even though the host name, sender and recipient address are all correct. I am using Windows 10 and R 3.2.2.

yep.. port 465 is correct. I still tried using port 995 and getting the same error. — viralshah009, Jun 06 '16 at 18:55
