Just had a customer complaining that emails are going going through.,
She can't reply to an email - but it is in her outbox - so must be my
problem (!)

In my log (exigrep), I see:

So who is to blame? That's 13 references? The Outlook ones are very
long. I dislike the way Microsoft "shouts" - like they believe they are
always right - but they would appear to be the cause of the problem -
very long references?

Can I reduce the maximum number of references perhaps to 10?
What else can I do to reduce customer anxiety?

I am the "zanet.co.za" side and the local references are reasonably short.

I think this email is now frozen   (-frozen 1699871109, -localerror ) -
so my frustrated email user will never see this - or what to do if she does.

What should I tell the customer to do? What can I do?
