I have 6 or 7 jobs that have email triggers, all using the same IMAP connection. Most of the time, they work nicely, but I do occasionally get a connection error just like the ones stated before in this thread. I'm not sure it's a problem with VC - I think it might be a problem with the mail server. I can't really prove that, so it'd be nice to be able to find out for sure, but I would think that the mail server might have a setting that says something like "if there are X connection attempts within Y seconds for the same account, block them" in order to prevent DOS attacks. With 200 jobs all checking every 60 seconds, the extreme scenario is that all 200 of them check at exactly the same time. I'm not sure how the mail server would react to that.
