Depends who you use for an ISP.. the from in your headers doesn't say (From: "Chips" )
Some ISP's require smtp authentication (log on to mail server) to be able to send email thru them. See if you ISP has changed to requiring authentication to send email now.
Did you try adding the domain? When I try and send email from my PDA I to have just the (name), but now have to put in the whole name (like) (name)@domain.com
It was in outlook express.. It asks for the name in it, but whenever I access it any way other than a direct connect (WiFi, cell, sat, etc) but it really wanted the (name)@domain.. It's free to try, and Worth a shot...
Some ISPs (actually most these days) do not allow traffic on port 25 to pass out of their networks in an effort to reduce the amount of spam that originates from their network.
The solution is to see if the e-mail server you want to use also uses a port other than 25 for SMTP and it would be best if that port would use encryption (e.g. SMTP with SSL that may be on port 465; Gmail has this but many other e-mail providers do not). Ideally, you would not be using port
25 in the first place because traffic over port 25 is usually not encrypted and if you need some sort of logon, your name and password would also not be encrypted. This is especially bad if you are using an unencrypted wireless network.
Okay.. so the laptop works wireless else but not there, and the desktop also won't work there wired.... Just for debugging reasons, can you connect the desktop direct to the dsl/cable modem and skip the router.. (just for a test)... That will narrow it down to the desktop or the router... Or does the laptop also have a wired connection, that you can enable and use wired? (sounds silly, but if you can try it that way, you know absolutely for sure where the problem is ((ie in your router or the connection to the ISP)). Makes debugging easier when you can narrow the error down to one device....
I'm using a Belkin Pre-N hub & card in my laptop. Wired to desktop.
Recently I stopped being able to send email through the main email server I use. I can still receive email through it. I can not send it from home using the Belkin router from either the laptop nor the desktop. None of the settings were changed, it just quit being able to send.
Now if I take my laptop to work where somebody else has a wireless network that is wide open, I can hook up to that with my Belkin Pre-N card and send or receive email through the same email server, and with the same settings. Just can't send from home.
The email server for my ISP still works fine for me. It's SBC (I think they use Yahoo).
The email server that I can't send through is run by my website hoster. He says I don't need authentication, and didn't change anything. Also, I tried changing this setting back and forth, and there was no success there in solving this.
My web hoster says there have been a few other customers of his that mysteriously suddenly could not send email through his server. He never figured out why.
Nevertheless, on my laptop, without changing any settings, I can send through his email server from somebody else's wireless router, but not through mine.
The desktop is wired, the laptop is wireless. The desktop has the same results as the laptop, except that the desktop has not been taken elsewhere to be tried on somebody else's network.
