IRM E-Mails Not Sent - Length of Text Line is too long without Carriage Return


Emails sent by the IRM test page or main page may not reach the recipient if the email contains long lines without carriage returns.  sender.  The following Symantec article describes this problem with respect to the Symantec Velociraptor Firewall

For information on line length limitations in Internet Messages, read section 2.1.1 of RFC 2282, Internet Message Format, which is reprinted below:

2.1.1. Line Length Limits 

There are two limits that this standard places on the number of characters in a line. Each line of characters MUST be no more than 998 characters, and SHOULD be no more than 78 characters, excluding the CRLF. The 998 character limit is due to limitations in many implementations which send, receive, or store Internet Message Format messages that simply cannot handle more than 998 characters on a line. Receiving implementations would do well to handle an arbitrarily large number of characters in a line for robustness sake. However, there are so many implementations which (in compliance with the transport requirements of [RFC2821]) do not accept messages containing more than 1000 character including the CR and LF per line, it is important for implementations not to create such messages. The more conservative 78 character recommendation is to accommodate the many implementations of user interfaces that display these messages which may truncate, or disastrously wrap, the display of more than 78 characters per line, in spite of the fact that such implementations are non-conformant to the intent of this specification (and that of [RFC2821] if they actually cause information to be lost). Again, even though this limitation is put on messages, it is encumbant upon implementations which display messages Resnick Standards Track [Page 6] RFC 2822 Internet Message Format April 2001 to handle an arbitrarily large number of characters in a line (certainly at least up to the 998 character limit) for the sake of robustness.

Solution - Keep lines in IRM Email Confirmations to less than 78 characters

Files to look at are found in the \IRM\UserText Folder and are:

  • EMailConfirmTop.txt
  • EMailConfirmBottom.txt
  • EmailOwnerConfirmTop.txt
  • EmailOwnerConfirmBottom.txt
  • EmailWaitlistConfirmTop.txt
  • EmailwaitlistConfirmBottom.txt

Make sure that each line in each of these files is less than 78 characters between each carriage return.
