This piece of code should send e-mail to someone@someplace.com - which it does.
It should also send "Blind copies" to other e-mail addresses, BUT all recipients of the BCC see the other e-mail addresses. A bug in SMTP??
B4X:
Sub Process_Globals
Dim Mail As SMTP
End Sub
....
....
.....
Sub SendIt
Mail.Subject="any subject"
Mail.Body="some body"
Mail.To.Add("someone@someplace.com")
Mail.BCC.Add("addr1@a.com")
Mail.BCC.Add("addr2@b.com")
Mail.BCC.Add("addr3@c.com")
Mail.Send
end sub
