XCON: IMC Might Stop if RFC 821 From Address is > 64 Characters

ID: Q152930


The information in this article applies to:
  • Microsoft Exchange Server, version 4.0


SYMPTOMS

The Internet Mail Connector will stop when it receives incoming mail if the RFC 821 "from" address is longer than 64 characters and there is no RFC 822 "from" address.


CAUSE

If the message does not have an RFC 822 "from" address, the IMC will only allocate 64 characters in which to save the RFC 821 "from" address. If the message contains an RFC 821 "from" address that is longer than 64 characters, the IMC will stop in the middle of the SMTP conversation.


MORE INFORMATION

If the message has an RFC 822 address, the IMC will not stop if the length of the RFC 821 "from" address is longer than 64 characters.

The RFC 821 "from" address is the address after the "MAIL FROM" command in an SMTP conversation. The RFC 822 "from" address is the address in the message headers, after the "From:" header.


STATUS
