Contrary to another review in this list, RapidoSMTP DOES work on MacOSX 10.4.9+. This machine is a MacPro Dual-Core Intel Xeon 2.66 GHz with Mac OS X 10.4.10 (8R2210) and Darwin 8.10.1.

There WAS a problem with PORT 25 - I moved things over to PORT 587 - and opened same in the firewall (not sure if that was really necessary) and am successfully sending eMail with impugnity. In my sendMail class I used "localhost." (notice period at end of string) and had no problems except for the fact that mail sent to ME at an external eMail address did not seem to make it all the way to that inbox. It may be that my ISP is thwarting the issuance of mail from MY computer to MY smtp conduit as a SPAM prevention measure. I need to contact them and ask if they can help me understand the current behavior.

The USER INTERFACE is attractive. It seemed like I had to reboot my system about 4 times as I went through the various INSTALL-REMOVE-CHANGE_PORT-INSTALL but then that's a MacOS EXTENSIONS feature where the existence of root-level extensions are not considered except at boot time.

Frankly, I am VERY happy to be able to make use of the MAIL facilities in my system as it lets me test Java software that is intended to run on a Linux system with no other modifications or special cased treatment needed to be performed.

If I HAD to provide some UI feedback, the ability to TEST the possibility of port 25 presenting a problem could be included up front so you did not have to go thru numerous reboot-cycles in search of something that would work. Also the question of what one might need to do with their firewall could be clarified in a single sentence.

Thanks VERY much to the App4Mac people for doing such a nice job with this FREEWARE! It was my good fortune to come here and find out about it.

Best Wishes,
