Email server consulting & support services by Linuxcare Vancouver

Linux email servers are stable, scalable and feature rich. Unlike Microsoft mail servers (exchange, Mail Enable, Kerio etc..) Linux mail servers such as Postfix and Sendmail are free software, features such as spam filtering, virus scanning are also free of licensing costs. It may surprise most people that Linux based mail servers already run a lot of the most high volume mail systems on the internet today. ISP's and Hosting companies often choose Linux as the primary mail server to host their clients due to the stability, features and scalability of the Linux mail server.

AmavisD is the new generation of Spam and Virus protection for Linux mail servers. This application rolls into a single package world class anti-spam and anti-virus. This feature can be integrated into many of the primary Linux mail servers such as Postfix, Sendmail and Qmail.

SMTP SSL authentication and Domain Keys

Better ways to keep your email secure.


We can help integrate SMTP SSL with your mail server for secure communications. Self generated SSL certificates or certificates from a certificate authority such as Thawt or Verisign.

Domain Keys to fight spam & domain spoofing

Domain Keys are an innovative e-mail authentication technology developed by Yahoo. It is designed to verify the DNS domain of an E-mail sender and the message integrity. Domain keys are not directly useful in spam filtering. However, widespread use of DomainKeys can prevent spammers from forging the source address of their messages, a technique they commonly employ today.
