    hey guys. i just moved to london and the house im staying in has ethernet. i have to sign in on safari and after i do it says some ports are blocked on the internet connection. I noticed I cannot recieve or send emails so i am assuming that its because those ports (110) are blocked. Anybody have an idea of which ports I should use or whatever so i can use mail rather than safari for my email. Spanks.

    The standard ones for mail are port 25 and port 587, try one of those.

    tried both of those and neither work. i had been using 110 in the states and never had issues.

    That makes no sense and I highly doubt your ISP is going to block port 110 as this is the standard incoming port to connect to a pop3 email server.

    Your ISP probably won't block this as you wouldn't be able to use one of their own email accounts they provided you.

    You should contact your ISP or email provider for information on what ports to use.

    587 is what I use at work and at home with no problems.

    The regular port is blocked at both for me so I switched to 587

    No luck

    I have upgraded to snow leopard and now I cannot send emails. I use orange and the message I get is

    "Verify that you have addressed this message correctly. Check your SMTP server settings in Mail preferences and verify any advanced settings with your system administrator.

    Select a different outgoing mail server from the list below or click Try Later to leave the message in your Outbox until it can be sent."

    I have no other mail servers and up until two days ago all worked fine.

    Tried switching ports, 25 110 587 no difference. So much for a smooth upgrade
