Java R sendmail ASPMX.L.GOOGLE.COM:25无法打开

各位，我希望你们能帮我一把

我试图通过R发送邮件，但遇到了一些问题

library(sendmailR)
from <- sprintf("<sendmailR@\\%s>", Sys.info()[4])
to <- "<myemail@gmail.com>"
subject <- "Hello from R"
body <- list("It works!", mime_part(iris))
sendmail(from, to, subject, body,
control=list(smtpServer="ASPMX.L.GOOGLE.COM"))


Error in socketConnection(host = server, port = port, blocking = TRUE) : 
cannot open the connection
In addition: Warning message:
In socketConnection(host = server, port = port, blocking = TRUE) :
ASPMX.L.GOOGLE.COM:25 cannot be opened

库（sendmailR）
