[IMail Forum] Intermittent Mail Error

[Andrew Cook]

Hi,

My IMail server gets intermittent errors on delivery.  99% of the time a
message will go through properly, but occasionally the sender gets this:

451 <[EMAIL PROTECTED]>...I/O error
Warning: message still undelivered after 4 hours
Will keep trying until message is 5 fays old


The box exists and gets other mail, even from the same SMTP server.  Any
ideas?

BTW - no problems with disk, 5 GB free, and no restrictions on this
particular mailbox for size, etc.
