Flash (Alert)


Abstract

Domino 9.0.1 Feature Pack 9 introduced a regression issue where the To address fields of messages become malformed and nondeliverable.This issue is fixed in Domino 9.0.1 FP9 Interim Fix 1.

Content

An issue was introduced in Domino 9.0.1 FP9 that could result in SMTP mail headers with random characters inserted into From, Sendto, and Copyto fields. This could then result in non-delivery of mail to/from Internet email addresses. 

Symptoms of the issue include receiving messages containing garbled sender names. Opening the message and replying results in a number of embedded garbled characters in the header. You can observe this by viewing the page source or by simply examining the content when opening an email. Another method is to capture the SMTP outbound message and examine the header.

Fix Available:
This issue is tracked as SPR# JCARAQSJB6 and is fixed in Domino 9.0.1 FP9 Interim Fix 1. For download links, go to the Domino tab in technote 1657963 - Interim Fixes & JVM patches for 9.0.1.x versions of IBM Notes/Domino & add-ons.

NOTE: The solution for the above issue in 9.0.1 FP9 IF1 specifically reverts the following fix that was implemented in 9.0.1 FP9. IBM will revisit addressing the below issue in Domino 9.0.1 FP10.

REVERT 9.0.1 FP9 SPR# TPON949L2M - Fixed an issue where encoded phrases may have embedded delimiters after decoding -- e.g., the comma (',') in Ziffle, Fred <fred.ziffle@zifflemail.com> causes an error for Notes. Fix is to unconditionally quote the decoded phrase: "Ziffle, Fred" <fred.ziffle@zifflemail.com>
