XCON: IMC Might Stop if RFC 821 From Address is > 64 Characters (152930)
The information in this article applies to:
- Microsoft Exchange Server 4.0
This article was previously published under Q152930 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
Microsoft has confirmed this to be a problem in Microsoft Exchange Server
version 4.0. This problem was corrected in the latest Microsoft Exchange
Service Pack. For information on obtaining the Service Pack, query on the
