1 month or so back, I registered with inbox.com because I read that they\nhave sophisticated challenge-response systems in place to stop spam. 80% of\nwhat I get each day is spam, and I'm sick of it, so this sounded like a\npotential replacement for my Unix based pine shell, which I've been using on\ndialup for 14 years. (it has no spam blocking whatsoever)\n\nI recently read that they were setting up pop email access, so you could\nuse programs like Eudora to do email offline, then connect for a short time\nto send and receive.\n\nI followed the directions and set this up. I thought it was working when\nI got a test email I sent from my other account in the Eudora inbox.\n\nLater, I found that for some reason, I can receive, but not send emails.\nI do fine on the inbox.com webmail - no problems there. However, I was\nreally looking forward to being able to compose email offline, since I am on\na limited time per day of dialup - 5 hours a day.\n\nSo, I wrote inbox and asked why this might happen. Here is what they\nsaid:\n\n\n\nSUPPORT ANSWER(10/24/2007 9:18:29 pm):\nIf you are unable to send/receive emails using Inbox.com account via Email\nClient, then please try to do Telnet test first to check if there is a\nconnection with any of the SMTP Port 25, 465 or 587 and POP3 Port 110.\n\n\n1/ click on the Start button,\n2/ then click on the Run,\n3/ type in the box the word "telnet" and press enter - new window will be\nopened,\n4/ type in "open my.inbox.com 25" OR "open my.inbox.com 587" OR "open\nmy.inbox.com 465" and press enter and wait until you will be displayed by\nany response,\n5/ also check the connection with port 110 - type in "open my.inbox.com 110"\nand press enter, wait until you will displayed by any response.\n\nIf any error message comes back (connection failed), it is necessary to\ncontact your internet service provider (ISP) to ask for help.\n\nI did all of the telnet tests, and all worked EXCEPT for the first one\n"open my.inbox.com 25" - it would never connect.\n\nMy dialup ISP is VTISP.com - they don't provide pop email with the dialup\naccount, mostly because they don't want to deal with support questions.\nIt's ultra cheap - .25 a month for 150 hours. However, now I'm wondering\nif I was wrong to think that I would be able to use Eudora.\n\nIs there a chance that VTISP actually has something switched off that\nwon't let me use Eudora? I'm currently stuck with 1 way email - in only!\nKind of annoying when people can write to you, but you can't answer!
