jpickeri Posted October 17, 2003 Posted October 17, 2003 This is a SMTP protocol error that the receiving SMTP server generated because of the contents of a command your SMTP server sent. It probably due to an extremely long line in your mail message. Is is difficult to tell. Which SMTP server are your using? Which mail delivery software are you using? Are there any long lines in your message? From RFC 821 4.5.3. SIZES There are several objects that have required minimum maximum sizes. That is, every implementation must be able to receive objects of at least these sizes, but must not send objects larger than these sizes. **************************************************** * * * TO THE MAXIMUM EXTENT POSSIBLE, IMPLEMENTATION * * TECHNIQUES WHICH IMPOSE NO LIMITS ON THE LENGTH * * OF THESE OBJECTS SHOULD BE USED. * * * **************************************************** user The maximum total length of a user name is 64 characters. domain The maximum total length of a domain name or number is 64 characters. path The maximum total length of a reverse-path or forward-path is 256 characters (including the punctuation and element separators). command line The maximum total length of a command line including the command word and the <CRLF> is 512 characters. reply line The maximum total length of a reply line including the reply code and the <CRLF> is 512 characters. text line The maximum total length of a text line including the <CRLF> is 1000 characters (but not counting the leading dot duplicated for transparency). recipients buffer The maximum total number of recipients that must be buffered is 100 recipients. **************************************************** * * * TO THE MAXIMUM EXTENT POSSIBLE, IMPLEMENTATION * * TECHNIQUES WHICH IMPOSE NO LIMITS ON THE LENGTH * * OF THESE OBJECTS SHOULD BE USED. * * * **************************************************** Errors due to exceeding these limits may be reported by using the reply codes, for example: 500 Line too long. 501 Path too long 552 Too many recipients. 552 Too much mail data. jim Quote
