TLS Certificate Issue

Open basilz opened this issue 5 years ago • 2 comments

Hi,

I am trying to send an email with tls=TRUE using this code:

send.mail(
      from = "[email protected]",
      to = "[email protected]",
      subject = "Test",
      body = "Test",
      smtp = list(
        host.name = "mailgwc.test.eu",
        user.name = "username",
        passwd = "xxx",
        tls = TRUE
      ),
      authenticate = TRUE,
      debug = TRUE,
      send = TRUE
   )

I cannot send any email due to an issue clearly related to a certificate missing but I have no idea how to fix it in this case with rJava in between and strangely I haven't found anyone who came across the same issue.

Here is my debug:

Hey this package repo was moved to: https://github.com/rpremrajGit/mailR and this issue has been resolved in the latest version of mailR 0.8 on CRAN.
