VFEmail Glossary of terms
I'm interested in using VFEmail's services, but I was wondering..
I've signed up for VFEmail, but I have another question.
Port 25 blocking is widely used by some ISPs to easily resolve two "problems".
First, it is a means used to block spam. By not allowing mail to be sent through any non-ISP servers, it is thought that spammers are prevented, at least in theory, from se nding out huge volumes of unauthorized junk email. The second, and more common use of port 25 blocking, is to prevent small, home-based businesses from using "residential" accounts for commercial purposes, which are billed at substantially higher commercial rates than residential. Thus, certain "key" ports (port 25 for email, port 80 for web, etc.) are prevented from working in both directions (i.e. you can surf OUT to port 80 for web pages but, no one can surf IN to your computer on port 80).
With Port 25 blocking, anyone logged in to an ISP access number will only be able to send mail through the that ISP's mail servers.
To tell for sure if your ISP does not permit you to use external SMTP servers, try to telnet to NL101.vfemail.net port 25. If you are able to get through, you should ideally see this:
$ telnet NL101.vfemail.net 25
If you get some other error, we will need to see the error to provide a diagnosis.
Many ISP's including AT&T, Earthlink, Mindspring and MSN do not ALLOW OUTGOING SMTP. Here are the information links for the various ISPs we have work with:
For faster resolution of this problem, please check your ISP's policy on this issue prior to contacting our support department.
Finally, as a last-resort, VFEmail provides SMTP/IMAP services over what are typically HTTP ports:
