SMTP server blocking - HELP!

In the past I have always used a local SMTP server to send mail - as has the rest of my family - as we join many different networks and a localhost worked well. Now, at home, through the Plusnet service we can no longer use the local host as Plusnet has blocked SMTP access for any server using a dynamic IP address.
Has anyone got a way round this?

2. Your IP will be marked as being part of a dynamic IP range. Some mail servers refuse to accept mail direct from dynamic IPs as this is a common way that spam is sent out.
3. Changing to a fixed IP won't change that, you'll still be in a range of IP numbers marked as dynamic, it's just it won't ever change.
4. The recommended solution is to set your server to relay all mail via relay.plus.net.

Are you sure it is Plusnet doing the blocking?

Although all of my DNS & MX records have been configured withGo Daddy they do not permit the direct use of SMTP [Port 25] email traffic, which means it is necessary to look elsewhere. Go Daddy suggestedasking your own ISP for a relay or sign up to a freelance company that provides email relays using a smarthost configuration.
You would think that this is a fairly simple question - Can I set a smarthost connection with my own ISP [Plusnet] or will I need run with a company called Socketlabs who provide for free 500 outgoing SMTP messages per month, anything over that a fee i applied.
Unfortunately, I have not been able to get this enquiry answered, so I do recognise your frustration,

+1 on all the above points.
We don't block access to port 25.
@Computech2000, the answer to your question depends on the volume of email you'd be planning to relay via our servers?

I run a small Sole Trader IT Support business from home and am currently implementing a Small Business Server 2011, both to run my own business, use as a training resource to study for the 70-169 MCTS exam in the hope that I will be able to market the same SBS setup to other of my small business customers.
Base on my current email traffic I do not anticipate sending out hundreds of messages on a monthly basis, just sufficient to deal with customer and supplier queries.
It would be nice to try setting up a smarthost using my own ISP (just moved from BT) rather that some unknown company like Socketlabs who are able to supply an FREE account with a maximum of 500 sent messages from my server.
If Plusnet will allow me to at least try out the relay.plus.net system I would be very grateful. If permitted I presume that I would use my existing Plusnet login information.
In the meantime thank you for your kind consideration.

To put it into perspective, a family of four sending only five e-mails a day each would come to 600 a month.

Worst case scenario would be that you start encountering 4xx or 5xx SMTP rejections after sending a certain volume of mail. The volumes you're talking about shouldn't lead to this though.

The message could not be sent to the SMTP server. The transport error code was 0x80040217. The server response was not available
I contacted Support but they said there was no smtp limits.
I have been using port 587 to date with no problems.
Any help out there?

That's not true.
There's a per email recipient limit of 250 and a per hour recipient limit of 1000. When you're sending from outside of the Plusnet network these limits will be much more aggressive.
