Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

try to resend that mail after it get back after five days, and get the same.
can anyone tell me, what direction i must to look and so on?
with another recipients i do not have similar problems, all work.
on other hand - i do not sure, i have an ssl3 links to another my email respondents.
my mailserver is slackware64 14.0 with default sendmail....
took a quick look at the sendmail source (i have 8.14.7 installed); the error is in file ./sendmail/sfsasl.c, function tls_read (line 717). The function SSL_read fails and returns a value of 0, according to 'man SSL_read' this means it was an improper shutdown.
According to 'man SSL_get_error', SSL_ERROR_SSL is a protocol error. Try to upgade to SSL-1.0.1e and see if it happens again.
but i do not change or touch my mailserver configuration for several months - and that problem get out about a two or so weeks ago. very strange. now i update openssl and openssl solibs to 1.0.1e and see, what happens
EG look, now it's works!
thank you very much!
but interesting, where is reason? because in my side there not be any changes for long time, and all works until suddently stops. there may cause by other side ( ellentech) upgraded their openssl and there starting some incompatibility between the machines?
ok, thank you again.
the first string, version=TLSv1/SSLv3, verify=FAIL
is, as i understand, because i have no SSL certificates? and if i have a selfmade certificates, without authority signed, i also do not have a good working ssl protocol on mail, as it is with http / apache ( https) ?
its not a big deal, simply want a bit more understand in that topic...
the server don't know the CA of the certificate your sendmail is using; for an home sendmail it's quite normal, simply, the server doesn't trust you by certificate, but you can have other credentials, like user/pass login
