Oddly missing emails

[Danita Zanre]

Hi folks!

I usually receive multiple email messages from a vendor each day.  About 
3 days ago, they seem, with a couple of tiny exceptions, to have 
stopped.  I thought perhaps they were having a problem with their order 
system.  It's pretty difficult to get together with their IT staff 
though, so I've been trying to figure it out from here.  This is the 
only "error" I see in the mail log, but these messages are delivered. 
I've searched for the IP address, the sender, etc. in the mail log, and 
only the messages that get through even seem to appear in the mail log.

The kicker is though that if I change my address on their site to my 
gmail account, all mail gets through.  I expect an email almost 
immediately when I place orders - 30 orders were placed yesterday with 
NOT ONE email acknowledgement, and today I have alternated orders by 
changing my address from my address that goes through mailscanner and my 
gmail account.  The gmail messages always make it and my own account on 
my corporate mail server do not.  Here is the only thing I can see at 
all - by the way, long ago I used Xeams, and my server name is actually 
xeams ;-) - so do not be confused by seeing xeams all over the log!

I have searched the log for the IP address, the host name, there are 
simply NO other errors.  I will note that the error about the hostname 
starts about January 25, but I received all mail as usual until about 
the 27.

Where can I look to find out why these messages don't even seem to make 
it to the mail log?

Thanks!
