What is Yahoo's mail server address to receive/send mail in Outlook?

Problems with my outgoing (SMTP) mail server with Outlook 2007.

  • Problems with my outgoing (SMTP) mail server with Outlook 2007. For some reason I was able to set up Outlook 2007 at my office just fine, but I can't get it to work at home. Incoming (POP3) is fine at the office and at home, but I can't get outgoing (SMTP) to work at all from home. I have checked and all the account settings are the exact same as far as I can tell. Really trying to work this but feeling lost. As a bonus boner, my inbox at work doesn't contain all the same received emails as my inbox at home. I'm going nuts here. Home Settings: (Same as work settings AFAIK) Your Name Joe J. Doe E-mail Address [email protected] Account Type POP3 Incoming Mail Server mail.domain.com Outgoing Mail Server(SMTP) mail.domain.com User Name [email protected] Password 1234 Remember Password CHECKED Require Login with SPA UNCHECKED Mail Account [email protected] Organization BLANK Reply E-Mail BLANK Outgoing SMTP Req. Auth. CHECKED Use same setting as my… CHECKED Connect using my LAN CHECKED Incoming Server 110 Outgoing (SMTP) 25 Use the following type… None Leave a copy of messages… CHECKED Error Message when testing settings: Send test e-mail message: Outlook cannot connect to your outgoing (SMTP) e-mail server. If you continue to receive this message, contact your server administrator or Internet service provider (ISP). This would seem to be an issue with my ISP, but I can login fine at work with the same settings. I'll be around checking today. God bless your little hearts.

    For some reason I was able to set up Outlook 2007 at my office just fine, but I can't get it to work at home. This is because at work you rely on your ISPs smtp server to send out your mail. So lets say your business is on AT&T but your home connection is on Comcast. You will not be able to connect. Now your home or business smtp might have some settings for outside of network use. You'll have to contact them or google for the right settings.

Your ISP typically will block outgoing port tcp/25. You can try alternative mail ports, such as tcp/465 (this is SMTP with SSL, so make sure your SSL is turned on) and tcp/587, the mail submission port. Note that your office may also block tcp/25 for relaying if the connection isn't encrypted, so you can try turning on TLS on tcp/25 to see if that helps. But, most likely, what you're seeing is your ISP trying to block off spambots by prohibiting tcp/25 to anything other than their own mail server.

To test chengjlh's theory, try this - from a command prompt, try to telnet to your mail server on port 25. For example: telnet mail.domain.com 25 Trying IP_address_of_server... Connected to mail.domain.com. Escape character is '^]'. 220 mail.domain.com ESMTP Sendmail 8.13.1/8.13.1; Sun, 24 Feb 2008 17:47:24 -0500 This assumes that your mail server uses sendmail, but I would think that the basics would be the same. I get the 220 response from a sendmail and a qmail server. I don't have an Exchange or Postfix server to test with. If you don't get the 220 response, you're not connecting to the SMTP port on mail.domain.com. This could mean something on your local network is blocking the port, but generally, it's your ISP blocking port 25 unless you're connecting directly to their mail server.

Ask your IT department if they have smtp over SSL set up, that sends on port 465 and is generally not filtered by ISPs. Ideally all mail communication would be over SSL, but i'm not your IT guy. :)

I saw this on re-read: "As a bonus boner, my inbox at work doesn't contain all the same received emails as my inbox at home". IMAP would fix that. The mail would live on the server instead of being downloaded to either your home or work client. You could access it from either machine and see the same messages each place. Again, IANYITG.

just to clarify, I work in a small professional office and we use regular business DSL. sorry for not making that clear. I am unable to telnet from the CMD prompt.

I'm using AT&T broadband at home btw.

Mr_Crazyhorse

Port 465/SSL is not working. any advice on how to get telnet access from the cmd prompt would be appreciated.

Mr_Crazyhorse

I am unable to telnet from the CMD prompt. Does that mean you can't get to the command prompt, or that when you try to telnet from the command prompt, you don't get the 220 response - you get an error message? If the former, what version of Windows? If the latter, what is the error message? Also, most "business" class DSL packages don't block any ports, while a lot of residential DSL/Cable packages do, and port 25 is a common one to block.

Vista Ultimate "'telnet' is not recognized as an internal or external command, operable program or batch file"
