updated code pasted here. So I guess CC is not an option at all? In that case is there any other package that would be useful?
require(sendmailR) to <- c("v...@abc.com") header <- list(cc=c("a...@abc.com")) x <- sendmail("t...@abc.com", to, "test", "testing", header=header,control=list(smtpServer=server,verbose=TRUE)) << 220 equity.xyz.com ESMTP Sendmail 8.11.7p1+Sun/8.11.7; Thu, 11 Jul 2013 21:31:43 -0400 (EDT) >> HELO HKD03836654 << 250 equity.xyz.com Hello HKD03836654.gbl.ad.net [169.34.175.142], pleased to meet you >> MAIL FROM: t...@abc.com << 250 2.1.0 t...@abc.com...
