Mysterious mail problem

[machman5]

Hello all,

I apologize if this question seems vague please bare with me.

Mail goes out, and everything appears to be fine, logs show nothing out of the ordinary (ie no errors), however sometimes (randomly), people wont recieve it. This very well could be an issue on the recipients side, but on the off chance its not, what IF ANYTHING could cause my sendmail server to do this?

The issue could be that the receiving server (due to a misconfiguration on your end) thinks that the mail sent is spam and silently rejects it.

Do you know of any misconfiguration on my end that would make the recieving server think its spam. (I did happen to wonder if perhaps they have an overzealous spam filter)

Oh BTW we are now Blacklisted.

Damn, what I meant to say was, we are NOT blacklisted.

Do you receive any bounce-backs? What does the header of the message look like?
