[OT] Problems sending e-mail via Zen

I switched ISP from Demon to Zen a few weeks ago, and am now 500 miles
from home, but cannot send e-mails, although can receive.
Am staying with my brother, accessing his wi-fi, as I have done many
times before. Web access is fine, as is receiving news and mail, and, I
assume, news sending. Is this something peculiar to Zen? Could always
send via Demon when connected via brother's wi-fi to his Virgin account.
Error message :
Wed, 15 Oct 2014 21:35:43 SMTP[C8299] <- 550-This is not an open relay.
To send through this server you must either be
Wed, 15 Oct 2014 21:35:43 SMTP[C8299] <- 550 on a Zen Internet IP
address or be authenticated over TLS.
Wed, 15 Oct 2014 21:35:43 SMTP command rejected while talking to
mailhost.zen.co.uk: DATA
550-This is not an open relay. To send through this server you must
either be
550 on a Zen Internet IP address or be authenticated over TLS.
Not a major problem, but assume this is because I am trying to use Zen
via Virgin?

you'd do at home when connected to Zen - which is probably a login to that
server without a userid & password. But at your brother's house you're
connected to his ISP instead so when you try to use the Zen server, they
have no idea who is making the connection.
The solution is (as it says) to use TLS, ie to do an authenticated logon to
the Zen server. Then Zen will know it's you, and trust you.
Ideally you should have used a TLS connection even when at home, so that if
you then went elsewhere the same same definitions would work...

with TLS.

If you are outside of an ISPs range of IP addresses, they will usually
deny SMTP send since it would open the floodgates to the spammers.
Hence you need to change your settings to authenticate your SMTP access
with your zen username and password, and also enable TLS encryption.
(I am not a turnpike regular, so don't know where to twiddle the settings)

Nope, quite a few ISPs do it like that.

Not all ISPs do it like that.

Yep, quite a few ISPs only allow you to send email
when you are connected to their service. Mainly so
their service can not be used as an open relay.
One obvious alternative is to use something other than
the ISP's email service for your emails. That has the other
advantage that you don't have to tell anyone when you
change ISPs, just keep using the email service you do use.

Better still NEVER EVER USE AN EMAIL ADDRESS TIED TO AN ISP!!!

Sheesh, plenty of free reliable email services out there that will never
cause you any grief when you change ISP.

What on earth has the email address got to do with it? The OP can't

establish a connection to the Zen relay. He *might* get bumped off
later but that would be a little unfriendly.
The OP has two options:
1) Configure his mail client to always authenticate with the Zen
"smart host".
2) Configure his mail client to send mail directly to the recipients
listed MX address.
The first is preferable on a device that can pop up almost anywhere
on the internet, otherwise you run the risk of your mail being tagged
as possible spam depending on where you pop up.

Sounds like you need a different port setting and authentication setting
when not on their network.
This is quite common nowadays.

ongoing commitment to provide excellent levels of support, "
I used to have a handy utility called Mailroam so all outgoing mail
was sent to local host, picked up by Mailroam which used the SMTP
server I had (last) selected via a dropdown. Worked really well till
authentication was required. On the plus side authentication has for
me enabled better roaming.
