SMTP for non-EUI mail addresses
SMTP stands for Simple Mail Transfer Protocol and is the standard for sending email messages between servers or from a mail client to a mail server.
When you configure any email application (e.g. Windows Mail, Thunderbird, etc.), you must specify the SMTP (or outgoing mail) server as well as the POP3 or IMAP (or incoming mail) server for accessing your Inbox.
You must enter a valid SMTP server setting in your email client to be able to send messages, even though you may be able to receive incoming mail normally.
The SMTP server used must be the one belonging to the provider on which you rely for your current internet connection.
if you are connected to the EUI LAN or EUI WiFi, or enter the EUI network via VPN Remote Connection, and you want to send mail from a non-EUI mail address (e.g. AOL, Yahoo, etc.), then the SMTP server should be set to:
These constraints are for security. A server which acts as an 'open relay', passing messages originating elsewhere and destined for somewhere else again, is vulnerable.
Spammers use relaying and the EUI, like most email providers, does not allow the transmission of outgoing messages coming from an external domain (you get an error report stating 'We do not relay').
Therefore as long as you use an EUI internet connection in order to send your non-EUI mail, you must temporarily set your SMTP server to EUI's one..
