SMTP
What
is SMTP?
SMTP (Simple Mail Transport Protocol) is the standard by
which email is delivered
on the internet.
What
is an SMTP server?
It is a program that downloads email messages from the email
program and forwards
them to their destination. When email messages are sent
from the email program, they
are not delivered directly to the recipient. Instead, they
are first downloaded by an intermediary, i.e. an SMTP server, which then ensures that they
are sent to the right recipient.
Every time an email message is sent, there are four factors
involved in the exchange:
1) The email program in which the message was generated
2) SMTP server which forwards the message to its correct
destination
3) Server which should download the message from the SMTP
server and from which the
recipient will subsequently download it
4) Email program of the recipient which downloads the message
form the server.
Do
I need to set up my SMTP server?
No. Our business directories, Global
Buyers Directory and Chambers
Directory, do not
require you to set up your own SMTP server. You only need
to key in the address of
your ISP's (Internet Service Provider) SMTP server at the
Email Setting option and allow
standard port 25 (the default port for SMTP server) and
our email program to send emails
if the firewall or proxy is used at your computer.
Can
I use another SMTP server to send emails?
Yes, our directory allows relay mode which can accept you
to set another SMTP server
other than your ISP's SMTP server.
What
happens if my ISP is blocking standard port 25?
Generally speaking, it will not affect sending emails if
you use your ISP's SMTP server.
However, it
will not work if you use another SMTP server or program acting your computer as SMTP server using
standard port 25 to directly send emails.
