When sending mail through MS Exchange 200, I keep getting 421 Too many errors on this connection -- closing Any idea???
julien cool Exchange has a limit on the number of mail messages that can be sent across a single SMTP connection. If you hit this limit, then you'll get this message.
In MS Exchange 2000 (and it seems in SMTP Server coming with IIS), there is a properties panel in the Default SMTP Server named "Messages" where you can tune :
- size of one message
- number of mails by connection (default is 20)
- total size of messages in one session
- recipients by message
