Note: An increasing number of cable and DSL providers (Comcast, Cox, Roadrunner, Verizon, etc...) are blocking the default SMTP port 25 except for their own mail servers. This is being done to help reduce the amount of spam sent from infected customer PCs.
Symptoms: you get an error sending mail, saying "could not connect to mail.his.com".
Solution:In order to send email through your HIS mail server from your cable/DSL account you will need to use SMTP port 587 for mail.his.com.
