This will depend on what you are comfortable with :) (aka a flamebait question). In DNS servers, you have djbdns and Bind as the two main contenders. I did get another DNS server notification on the opennic list, but until I go through the code, or wait for other people to do that, I wouldn't recommend it on an internet facing server.
DJBdns is the more secure one of the two, but bind has improved a lot. In mail servers, your main contenders are: Sendmail, Exim, Postfix and qmail. Sendmail: Its strengths are that it has been around for a long time, and has good support. Its the default MTA with most unix systems. Weaknesses: sendmail.cf, monolithic, and administrators using linuxconf. sendmail.cf is not to be touched humanly, you are supposed to edit sendmail.mc and generate sendmail.cf using m4. Older versions of wsendmail needed root privileges, the newer ones don't. http://www.sendmail.org Exim: It is a single monolithic binary, with the easiest config to parse by humans. Can handle high loads far better than sendmail. http://www.sendmail.org Qmail: Consists of a large number of little processes, each running as a separate user. This has been designed for security, and the config is in a large number of little files. Not very polite to other internet users, it sends out one mail per recipient even if they are in the same domain. http://www.lifewithqmail.org Postfix: Has a number of binaries doing their own stuff, config is a single human readable file. This has been designed with security in mind, and has very good support in the mailing lists. Sends out multi-recipient mail if it can. This has a single configuration file. http://www.postfix.org My MTA of choice is postfix. It has a very light load on the system, and is very polite by default. > NB: Expecting more tips & tricks on this regard... Tricks to do what? Optimize your MTA? Select your MTA, and then read its documentation for how to scale it, and how to use RBL type lists with it for blocking spam.
