Error: NO MAIL SERVERS FOUND
If you get numerous of these errors, such that each e-mail you attempt to send results in this error in the log file, then the DNS server needs changing on the settings control. Look at getting started option on the left for full instructions.

Error: Server refused connection
Unfortunately, many servers, including the big ones like AOL have taken massive measures to block spammers using their servers to send out mass unsolicited mail. They block connections to dynamic IPs and it doesn't matter what SMTP server you use, the servers implementing this will always block you.

Other SPAM errors
If you get other Spam errors in your logs, it's most likely these servers are doing as above. They will not let your proceed to send mail, in case you are a spammer. This happens if you have a dynamic IP such as on dial-up accounts.

My ISP blocks port 25
SMarTPost will let you change the port that incoming clients communicate on, such as from 25 to 8080. But some ISPs block port 25, meaning if any program on your PC attempts to send out on port 25, it is routed through their own servers instead of yours. SMarTPost must send out on 25, and in the event your ISP blocks the port, SMarTPost cannot work. This is the same for all SMTP servers you can download.
