Can't send emails with an attachment

Ok, i am with ntlworld. I can send all things fine on my account, but my brother cannot send files with attachments on his - it results in "mail delivery failed "

if i turn on message scanning with norton systemworks 2004 it just gives him an error saying "message not sent "

We are using Microsoft Outlook 2000 btw. Anyone knows what could be the problem?

thanks

 

How big are the files he's trying to send? More and more ISPs are implementing a 2-meg file size limit on email. He might want to call his ISP and check on both that and whether they have also implemented a virus/spam filter. Either a file-size limit or a filter at the ISP may be blocking the sends.

If there is no problem on the ISP's end, check out the MS KB articles, Cannot Access Attachments, and Outlook or Outlook Express Hangs After You Send an E-Mail Message That Has an Attachment.

 

email attachment...

you didnt say if you had a router or the OS...some routers have whats called a MTU size, which is Maximum Transmission Unit...if your using A DSL connection there is a problem with that being set at 1500 and you can get this error...if using a router you change change MTU to 1492 and if its a WinXP they are also having a issue at times with MTU at either 0 or 1500 and this link talks about changing MTU in Win XP (http://support.microsoft.com/default.aspx?scid=kb;en-us;283165)...

hope this helps...i work at a ISP and know of the router issue and of WinXP possibly causing this...
