there's definitely an issue somewhere.
i am getting emails now that are 1 hr old.
one, a bounce message, came in as follows:
66.218.66.166 failed after I sent the message.
Remote host said: 451 timeout (#4.4.2)
I'm not going to try again; this message has been in the queue too long.
also, i have not got an auto-response for a ticket i sent in.
