We have just started to have this problem with sending some messages to accounts on hotmail or windows live. It doesn't seem to make any sense. Is anyone else experiencing this? Strangely some seem to get through with exactly the same content from the same address to the same recipient!


SMTP error from remote mailer after MAIL FROM:<> SIZE=5282:

Reasons for rejection may be related to content with spam-like characteristics or IP/domain reputation problems.
