i have a unique situation. i have a user that is unable to send a particualr email with certain conditions. the email is a small excel attachment. that delivers interally perfectly fine, but fails externally. actually it hangs in queue and eventually fails.
the user can email to individuals all day long but when you add mutiple people (3) to the recipient list with the attachment it never leaves the queue.
4.7.7 delay error connection dropped by host.
funny thing is that one of the domains this user sends to doesn't have any filtering enabled.
it seems to be a failure on the sending server not the receiving server since it is for mutiple domains.
any help would be great.
