Hello Everyone,I have configured my server to allow only emails under 10 MB this works great on Exchange accounts but here is the issue, Company users at home using POP email accounts send emails thru our company exchange server and as you know they love to send Photos that exceed the 10 MB policy. The server rejects the email the senders get a error message from Outlook stating Your server has unexpectedly terminated the connection. Possible causes for this include server problems, network problems, or a long period of inactivity. if the home user dosent see the message the email tries to resend again only to be rejected, I was wondering if there is a registry setting that would do more then reject the message.When an exchange account sends an email attchment tool large it is deleted with an Undeliverable email sent to the user or it cant be attached to Outlook due to the size.Any thoughts ? ?

Hi Walter. Quick Question. Why are they using POP? OWA or RPC over HTTPs ( Outlook Anywhere in Exch 2007) would be a superior solution and would eliminate these issues.

If the global message size limit is 10MB they'll stillencounter the problem.If those folks are using an ISP, why not use the ISP's SMTP server asa relay?---Rich MatheisenMCSE+I, Exchange MVP--- Rich Matheisen MCSE+I, Exchange MVP

He wants a NDR generated to the user or to prevent the uploading of an oversize message. Using OWA or Outlook Anywhere will solve that."Your server has unexpectedly terminated the connection.

Althoughhe really didn't ask about using a different mechanism for sendingemail, just about a registry setting to make SMTP do the same thingas an "Exchange account".Semantics . . . go figure. :-)---Rich MatheisenMCSE+I, Exchange MVP--- Rich Matheisen MCSE+I, Exchange MVP

lol. Yea, Well, thats the way I read it. :). But hey, I've been wrong before!

Hi,Whether the POP3 user can send the normal email without attachment?I have tested on my lab, the NDR can be received when the email's size exceeds the limit for the POP3 user.From the symptom, it seems that there is the connection issue between the POP3 client and Exchange server.ThanksAllen
