Sounds familiar.  People are too often completely ignorant.  They don't care
that simple upgrade of any component of email system (from email client 
to SMTP
server to IMAP/POP3 server) can couse problems again (crashing the 
email clients
or simply causing delivery problems again).  The only thing they care about is
to delegate problem to somebody else.  If your organization decides to swtich
to Cyrus IMAPD (for example) in the future, his emails are going to start
bouncing again.  Luckily, this time, you would be able to tell "I can't do
anything about it, it is erorr in client's software that generated those
emails, and it can only be fixed in that software".
