Question

Blacklist mail server settings

Hello there,

I work with a small startup company and recently, many of the client email servers have begun to mark my company's mails as spam, i.e, it directly goes into their spam mail. For some servers such as gmail, the mails don't go out from our server at all. Our network admin here told us that he called Google at that it'll take 7 days for them to whitelist our server. I have no idea how our server got blacklisted by the various mail servers out there. I just wanted to know whether we can trust this network admin of ours. Can't be too careful these days. Could someone tell me why mail servers get blacklisted automatically? The admin here says it's because of the numerous number of mails that come into and out of our server. I have a hard time believing that which is why I'm here. If this is the reason, then how do big servers like Gmail,etc. work? They must have 100x the number of mails going in and out. Any idea?
