287032 - Return receipt sometimes sent second time

Status: RESOLVED EXPIRED

(SeaMonkey :: MailNews: Backend, defect)

Sometimes a return receipt is sent a second time for a very old message that is
read again.

Reproducible: Sometimes

Steps to Reproduce:
1. mail configured, IMAP account (UW imapd), no prompting for return receipts
2. lots of messages in your inbox or other folder, already read
3. you are doing some searching or cleanup and read old messages again

Actual Results:  
Sometimes the original sender of a message receives another return receipt

Expected Results:  
Return receipt has already been sent before, should not happen again

We have first been using Netscape and then moved on to Mozilla.
At first I believed the above was caused by this transition, as it appeared that
Mozilla would not always recognize the "MDN already sent" indicator from Mozilla
and thus would re-send it.
However, it now appears it can also happen with messages received after the
migration to Mozilla.
It can sometimes have nasty effects as senders believe their message has only
been read after a year or so, or get reminded to an issue solved long ago.
