(Sorry, I missed your immediate reply) The from addresses you configure for each account should match that account. I can't send "from" chrisridd(a)mac.com using the VM SMTP server, only using the MobileMe SMTP server. Being able to mix and match would be very insecure and lead to things like account spoofing. What if I could authenticate to VM SMTP and send "from" steve(a)mac.com? How would VM's SMTP server know this was a legitimate thing for it to do? ISPs are also publishing SPF records in DNS, which allows ISPs to say that mail from their particular domain (isp.com) *can* only come legitimately from one of their SMTP servers. Sending "from" chrisridd(a)mac.com using a VM SMTP server would violate that. >> For example, I use primarily two accounts - a BTconnect one (I pay �5 a >> month to keep this as a basic address) and a Compuserve one (now free). >> I quote either of these in my outgoing mail using VM (I don't use VM >> mail) but I use the VM smtp server to send mail.

Most ISP's will only allow use of their SMTP server for email addresses allocated by them. Many ISP's, including BT, block access to third party SMTP servers. A way round this is to change the port number from 25 to 587 (this is the most usual alternative port but check with your email provider). Some ISP's will even block the alternatives. Generally speaking you can only use a from address that is tied to the ISP operating the mail server. Some ISP's, and BT is one, will allow you to use your own domain name email addresses once you prove to them you have the authority to do so. A fairly simple and free process aimed mainly at their business customers. Google will allow use of your own domain name for sending. To set this up go to your settings in gmail. It works. The best way out of your predicament is get your own domain name and use that for all your email routed through gmail. -- http://www.dream-weaver.com/email.php Web development promotion and seo http://www.spaldingcomputers.co.uk http://www.overseasmovingsolutions.com/

Also, some do block access to third party smtp if Ray's right in his post, but he says you can get round it in some cases. So it seems that at present VM is an open system. > Yes, paid/unpaid is not the issue here. It is is you have to pay to get to the smtp and POP. I'll see what happens if I try and use the Compuserve and BT smtp servers (although I do pay a small amount for the Bt address). E.

What really matters is the return path, not the From: header, in any case. (Doesn't mean that there aren't ISPs that will insist you get the header 'right' too but it's more tedious to check for.) Of course your client might not allow you to set these things to different values making the distinction moot... -- http://www.greenend.org.uk/rjk/
