Not receiving email

I noticed this morning that when my wife forwarded me a message, complete with all the others to whom it was sent, it did not come in. I am using OS X 10.4.9. I tried several more times to send the forward from her Mac, (in the next room), and nothing even shows up in the Log. I then sent a test message to my Mac from hers and it came through, as did several other forwards from her Mac. Is there something that prevents multiple recepiants emails from being forwarded?
Thanks,
Ken

SpamSieve does not affect which messages are received. All it does is move the spam messages out of the inbox and into the Spam mailbox. So if you don’t see the message in the Spam mailbox, then the problem is not related to SpamSieve.
