I'm relatively new to Linux (Ubuntu) but have manged, thus far, to get it installed on my former Windows machine when I purchased a new desktop. A month or so ago, I cedided to install Apache and VSFTP on it which proved to be a reasonably trouble-free task though I'm sure there's lots I haven't even considered. Two weeks ago, I decided to try my hand at installed a mail server. This, unfrortunately, has turned out to be a taxing process and I'm in way over my head. The problem is further complicated by the fact that I have a severe visual impairment and use screen reading software to acess written material. As a consequence, I find myself editting configuration files on a Windows machine equipped with voice sythesis and then copying the files back over top. Not for the faint of heart. There are a host of help guides out there many of which are somewhat dated so I was looking for something recent dealing specifically with Ubuntu 12.04 so that it would be relevant to my software. I have used the guide at: http://www.exratione.com/2012/05/a-mailserver-on-ubuntu-1204-postfix-dovecot-mysql/ but, of course, it doesn't work. I'm not sure where the problem lay. It's likely several problems or several things that have to be addressed. And, not to overstate the fact, I am very new to linux. I'm hoping I can find someone in here who can walk me thorugh the process, one step at a time, and help me sort out where I've gone wrong. I expect it's going to take some time to sort out and there'll be a bit of a learning curve on my part. (Patience on yours I hope.) When I try to telnet into the localhost 25 it reports: Trying 127.0.0.1... Connected to mail.mydomainname.com. Escape character is '^]' Connection closed by foreign host. The latest entry in /var/log/mail.err reads: Sep 19 15:50:13 mail postfix/smtpd: fatal: no SASL authentication mechanims Help and patience greatly appreciated.
