You need to give information about what exactly you are trying to achieve. Exim and postfix are both good choices, but there are setups that are easier to do with either one or the other. Sendmail can be difficult to configure --- which is an euphemism. Exim is my favourite. I found it extremely easy to configure, the documentation is outstanding, and the support that you can get from exims mailing list is great. It also has always been working totally reliable both on my comp at home as well as for the company I've been working for. If a mail server is "safe" or "unsafe" depends on what you mean by "safe"/"unsafe". You can configure exim in such a way that it might not be considered safe, and the same is probably true for postfix and sendmail. If you're worried about security, you can have a setup involving two MTAs on two different hosts one of which is visible to the outside to receive and to send mail like a smarthost while the other one is only visible on the internal network except for the communication with the smarthost. Exim gives you control over the resources it uses. This allows you to set up the MTA in such a way that it remains fully operational even when having to deal with enourmous amounts of mail. I don't know if postfix has features like that ... -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe". Trouble? Contact listmas...@lists.debian.org
