Recently, (in the last 2 days or so) I noticed that emails that have attachments or hyperlinks contained in the body of the message are not being received by various recipients. The email shows up in my "sent" box as if it was sent, but the recipients never receive the email. After reading the forums here, I did some troubleshooting and tried sending emails with attachments while in SAFE MODE and that worked! But, the problem is, I don't know why it worked, so I can't fix it.
Any possible solutions?
