myself321

Hi there

i can not send emails from my own private email address over my isps ( the post office) smtp server (smtp.mypostoffice.co.uk)

i have got my post office email address setup correctly and i am able to send and receive fine

my domain name email address incoming working fine but obviously can not send any out. i use Thunderbird i also tried windows mail , same message on both as below

The message could not be sent. The authentication setting might not be correct for your outgoing e-mail [SMTP] server. For help solving this problem, go to Help, search for "Troubleshoot Windows Live Mail", and read the "I'm having problems sending e-mail" section. If you need help determining the proper server settings, please contact your e-mail service provider.

the PO does not require Outgoing server requires authentication.

it seems as though if its not a post of email address sending over their servers it rejects it?

i had no problems sending emails over my previous isp (plusnet) servers from my own email address

the only setting that have changed is the outing server is po and not plusnet and i have set up my po email address which works fine. please help

Its worth asking their customer support whether they allow this, otherwise you might need to use a 3rd party SMTP service as I do

are there any good free or paid for 3rd party smtp

It sounds like PlusNet are blocking SMTP port 25?
Some ISP's do this, check your PlusNet documentation.

hi there PROLIANT i take it you mean Post office i am no longer with plusnet
so they let email be sent from their email address through port 25 but block any other email address from sending ?

I use mailcore from verygoodemail.com and have done for years. I have my own mail servers for inbound mail, but relay all outgoing through their SMTP servers. This is solely because some mail servers do not like the fact that I have a dynamic IP address and won't accept mail from me directly

I have no affiliation with verygoodemail.com other than a satisfied customer

myself321

how much do they charge per year , i guess you can send from any email address through their servers

myself321

just spoken to the PO they only allow PO email address to send of the server , are there anymore free/ good priced 3rd party SMTP providers, many thanks for everyone's help

Many hosts run mail on a second port to help circumvent isp's blocking port 25,
If you have your domain name hosed then try asking your host if they can help

my domain name provider does not offer smtp, what are the other options , many thanks

get yourself a cheap web hosting package and domain and use the email through that!
