Ours sales people have attempted to send mass emails of 100 recipients each (about 3 of them in a row).. Are there any reasons to tell them to not do this.. ie: greylisting fears etc.. I'm concerned because there are some SMTP errors in the log that are a little alarming.. What is also the best site to check to make sure we aren't on a spammer list of some kind.. My other concern is that we are still experiencing an issue we had years ago, which i thought was fixed recently, as comcast went to a true static ip here.. previously.. if emails were sent from our comcast connection (and not the other verizon one).. they would fail to reach their targets.. so we always had to make sure we sent on port2.. this hasnt really been an issue.. here are some examples of errors in the log file: Error Code: 10060, Error Message: A connection attempt failed because the connected party did not properly respond after a period of time Lots of 550 user unknowns (i'm sure this is just a wrong target address).. 452 insufficient system storage (i'm guessing this is just the target address's mailbox is full) 451 Your message has been greylisted, please try again later", "250 You are about to try to deliver spam. Your time will be spent, for nothing.", 250 Hello, spam sender. Pleased to be wasting your time.", 451 Greylisting in action - please try again later (TEMPFAIL), Thanks

http://www.spamhaus.org/ is good for blacklists, etc. Also, implementing things like senderID (www.openspf.org) or (www.microsoft.com/senderID) will help get through. IF you are sending unsolicited mail and in the US, be sure to follow the federal law...search for "CAN SPAM ACT" and you'll find everything you need to know.

Would using a tool like this type of mail merge be helpful?: http://www.sperrysoftware.com/Outlook/Microsoft-Send-Individually.asp Or even the built in mail merge (though i would think the messages would need to be seperated by a delay between them, which is what the above app does)? I'm also thinking that our sonicwall email security device would be useful, as it can be set to limit outbound email connections to 60 at a time.. right now i dont have it processing outbound emails.. only inbound? Thanks

I haven't used it, so i don't want to vouch for it, but it could. Also, take a look at ESP's (Email Service PRoviders) They'll do your marketing/sales blasts for you and SLA inbox delivery, provide reports on click rates, and do auto-unsubscribes. THere are also 3rd party apps that do that. I use one called arial http://www.arialsoftware.com/ I can't say i love it, but it works.
