Im very new to sendmail. Im using sendmail 8.12.9 and when I send mail out to others such as hotmail and yahoo through my server, it gets put in the spam folders rather then in ther inbox ? Ive been searching alot for the things I need to change but not have much luck. Im using webmin and sendmail m4 to make changes. Any help would be greatly appreciated
A lot of mail service maek e-mail sent from "consumer" IP ranges (i.e. those used by major broadband and diaslup ISPs) as spam. The reason for this is many home systems running Windows are compromised by the virus/worm of the week and used as zombies to send spam. So if your server is running on a consumer IP address, this may be an issue. Another thing to check is to make sure you don't have your server set as an open relay. Open relays are often abused to send spam and are usually quickly marked. Make sure you have all your domains to relay in /etc/mail/relay-domains and that sendmail is using this file (most distro's sendmail enable it by default, but you should check).
thanks for your reply. I am on a consumer IP and relay domain is set. I assuming this is only going to be a problem on servers such as yahoo and hotmail or pretty much most other mail servers with spam control. How would a person go about getting an ip that would fix this problem ?
Probably the best way is to sign up for business class service. Depending on your ISP's TOS, you may not even be allowed to run any sort of server on their network unless you shell out for the business class stuff (again, actual policy and enforcement will depend on your ISP). You might simply want to bounce all of your outgoing mail through your ISP's mail server (the smartserver setting in the config IIRC) to avoid the hassle. Since you're in their address space, the ISP's SMTP server should be willing to relay for you.
Please do not post the same thread in more than one forum. Picking the most relevant forum and posting it once there makes it easier for other members to help you and keeps the discussion all in one place.
