Linux Email Server Administration

Few, if any, companies have been providing Qmail support longer than tummy.com, ltd. We first started running and supporting Qmail in 1996, and have used Sendmail since our company inception (and before) in 1995. Our first installation of the "new kid on the block", Postfix, was in 1997.

Whether you are running Qmail, Postfix, Exim or Sendmail, we can help you with your Linux Email Servers.

From experience with e-mail servers at regional ISPs with 20,000 users, down to small-business mail servers, we have the experience you need.

Spam, Viruses and Malware

Spam, viruses and malware are a problem that we all face. We currently use a combination of greylisting, SPF, Spamassassin, and other tools to manage our mail, and have good luck setting up similar systems for our clients.

Reliable Email

We can help you take back your e-mail box from the spammers. We know how bad it can be. Because our company has been on the Internet since 1992, and has a fairly high profile site due to our heavy participation in the Linux community, we have gotten up to 4,000 spams per day per employee. A rate that no human could ever hope to keep up with.

Through innovative use of technology, we currently get only 2 to 4 spams through to our normal mail-boxes per employee per day, with only one or two messages per month total which are incorrectly classified as spam.

If you are running a mail server for a group of users, you know how much they rely on a smooth running server. We can help you set up:

High availability mail servers
High reliability servers
Offsite secondary email servers
Spam filtering
Virus filtering
Email archiving
Secure email servers
