Smtp problems

i have rcn. won’t recognise smtp servers…what happened?

What’s the exact error you’re getting? If the SMTP server name doesn’t resolve, talk to your ISP (assuming you’re using their DNS servers). If connections time out, your ISP may be filtering outbound port 25 traffic. Change your mail client to send mail through DH’s SMTP server on port 587 (not recommended, as you’ll have to send your username/password in plain text) or use your ISP’s SMTP server.
