I'd been happily using the CDOSYS component with "127.0.0.1" as the E-mail server address but for some reason Gmail are now blocking emails being sent like that (I checked with another email address that sending emails was not a problem). I'm seeing in the SMTP logs that the gmail servers are returning "Our+system+has+detected+an+unusual+rate+of " errors so I'll see if I can get that sorted...not holding my breath!
I'm wondering if there is a MOD, even a hard coded one to send email using GMAIL's servers directly smtp.gmail.com and inputting login info ?
