SMTP problem: email staying in C:\Inetpub\mailroot\Queue

Discussion in 'C#' started by alanX, May 5, 2007.

    Hi all,
    I wrote a send-email program using asp.net. It works in my school computers.
    However, when i use this program to send the email at home, then emails can not be sent and always forwarded to
    I have installed SMTP server( window XP prof.), but my home computer does not have a domian name(Just a IP address)
    SEMrush
    I have used the telnet ("telnet IP-address 25") to test the port 25. It is ok.

    Can anyone tell what problems on the SMTP server or anything else ?.?

    I would look into mail forwarding - it looks like it either doesn't know where to go next, or it's not being queued. You have standard install of IIS? Do you have a Firewall that's blocking port 25 for reqeust? Are you behind a proxy?

    (1) i have installed all the sub-components of IIS, including SMTP server
    (2) Port is not blocked by firewall ( I test it by turning off the firewall)

    (3) I don't quite understand "Are you behind a proxy"
    Does it mean the ISP or else?

    It means, are you on a network that you have to connect to a proxy to use the internet.

    i've been looking answers for the same problem, i get "Messages stuck in the queue" and while i was trying i notice something that could be the solution (centainly not the professional answer):

    1. click start, control panel, administrative tools, IIS services
    2. expand PC and right click "default virtual SMTP server"
    3. select delivery tab (spanish: ENTREGA)
    4. set lower values for: "first retry interval", "second try interval", "third retry interval", "subsequent retry interval"... (i set them to 1)

    now it's working fine for and hope this to be usefull
