Test to see if your ISP blocks external SMTP





Testing to see if your ISP allows you to use external SMTP servers

 

Open a command prompt, you can do this via...

 

Start > Run > Type "cmd" and press "Enter"

 

(Note: If "cmd" does not work please try "command")

 

A black window will appear - in this window type the following...

 

telnet mail.dc-servers.com 25

 

(NOTE: If you get any prompts about telnet trying to access the internet please allow it)

 

If you receive the line

 

220 mail.dc-servers.com ESMTP

 

Then you are OK - please type "quit" and press enter


 

If you get a timeout error this means your ISP is blocking external SMTP servers - this is becoming more and more common - but do not worry! We also operate our SMTP servers on a non standard port as well so you may still be able to use our SMTP server - click here for details

 

If you get a response but it is NOT from mail.dc-servers.com then your ISP is redirecting the SMTP service - most likely to their own SMTP server (Or you may have some sort of proxy)
