Help... 503 Valid RCPT TO must precede DATA / Packet Loss
Whenever I or any of my clients try to send OUTGOING e-mail (that is, not to one another on the server), this error is given:503 Valid RCPT TO <recipient> must precede DATA
Anyone know any fixes? This happens when using Outlook, for example, but does not happen when using e-mail.
Also, there has been an increase in packet loss recently. Anyone know any way to fix that? Thanks.
