All, like a numpty I thought I could save money and hassle by changing ISP. All has gone fabulously well. Except I can't send any outgoing mail! I have two accounts, one for my personal use, and one firstname.lastname@example.org, which should be self-explanatory. Until now, I've put the details of the mail server (easily for the personal one and 'hols' for the 'hols' one into the POP3 server box, and the name of my ISP's smtp server in the SMTP box. So, I thought it would be just a case of changing from the pipex one to the post office one. However, I get error messages along the lines that 'Outlook cannot connect to your outgoing email server' or 'cannot find the email server, Client host rejected, access denied'. Speaking to the techies at the Post Office I've had two responses. Helper 1 said 'no ISP will relay email for a mail that's not their own', and was taken aback to hear that I'd been using my easily account for about fifteen years. He then said the Post Office doesn't support third party suppliers. Helper 2 (today, when I'd calmed down) says that it's a problem with the email providers. Which I think is odd, given that they are not the link in the chain that's changed! Anyhoo, I now have an email from a person on email@example.com that really needs an urgent answer, and I'm fed up with using Faceache as a way of contacting people rather than email. Can any of you clever types shed any light, please?
