I'm getting NDRs while sending Email from Exchange 2000 to Jana-Server. Ehlo... 250 OK Mail from...250 OK Rcpt to... 250 OK Data... 354+Ok,+send+<CR><LF>.<CR><LF>+when+done 500+Synax+error,+command+unrecognized+(line+to+long) What does this mean? Witch configuration should I change on my Exchange 2000? Thanks, Daniela
RFC-2821 defines a 1000 character limit (including <CR><LF>) per line. 1001 for dot suffing in DATA. If a message exceeds these limits on any given line then a server may optionally return an error. Exchange 2000 and 2003 will accept and relay messages, unmodified, that exceed this limit. It should not generate any when transforming content or creating new messages. There is no setting to change this behavior. This type of problem usually indicates a bug. It could be Exchange or it could be the client submitting the message. It is also possible the remote server miscounted the bytes or got into the wrong state. Finally "bare LF" characters (not allowed per RFC) can have an adverse effect on some servers. If you can examine the transmitted data using a tool such as Netmon and carefully count the bytes it will be possible to narrow down the source of the problem. More details on how the message was submitted such as client version and type of access (MAPI/POP/IMAP/WEB) will also help. http://www.microsoft.com/resources/documentation/Windows/2000/server/reskit/en-us/Default.asp?url=/resources/documentation/windows/2000/server/reskit/en-us/iisbook/c05_netstat_and_netmon.asp -- Please do not send email directly to this alias.
