Hey guys/gals and thanks in advance! I can not send mail from Apple Mail but can receive. What's strange is that I can send from my office at school, but not at home. I was able to as of a month ago but can not do it now. What's especially strange is that my wife can do it from her computer with the same Apple Mail settings and I can send from my iPhone on my home network. Both of my accounts (Gmail and school) will not send from home. I didn't make any changes, so I can't figure out what happened. I even went in and deleted my mail pref files to no avail. I have Cox Communications running OS 10.5.6 with Gmail outgoing set to: Using default ports with SSL with smtp.gmail.com. My username and pswd is correct. My school account is set to the default ports with what I had before for the smtp server name that worked before. Overall, I think my setting should be fine because they work at school. I just don't know why my computer won't allow it to send from home.
