currently we ran into some issues with our mail server setup. im preparing a list of actions that we should enforce and use in order to maintain a proper email solution within our company.
we have around 80 exchange users, and send mass emails out almost on a monthly bases to 20,000 + customers each time..
the checklist i currently have:
1) mcafee mxlogic 'cloud' anti-spam functionality for incoming message.
2) antivirus on each computer in company
3) antivirus on exchange and DNS servers
4) setup SPF record
5) setup DKIM
6) setup domainkey
7) setup senderID
8) submit spf to microsoft, yahoo, etc. for 'whitelist' purposes.
9) configure size limits for messages in exchange to safe numbers
10) i have 2 outside IPs for my email server, incase one gets blacklisted, switch to the backup.
11) my internet site rests on a different ip than the mail server
12) all mass emails for company sent through 3rd party company (listtrak.com)
13) setup domain alias, media, enews, and bounce for the 3rd party mass mail software.
14) verify the setup using
[email protected]
15) configure group policy and our opendns.org account to prevent unwanted actions and website viewing
mass emails:
1) schedule them to send different amounts at different times (1,000 at 10am, 1,000 at 4pm, 1,000 10am next day)..
2) setup user prefences, decide what they want to receive ect. ( there interests)
3) send a more steady flow of email, maybe 100 a week with top new products instead of 20,000k every other month..
if anyone has suggestions or additions/subtractions to this checklist they are greatly appreciated.
thank you
