[05:19] <Neo4> hi
[05:20] <Neo4> read this "The mydestination parameter specifies what domains this machine will deliver locally, instead of forwarding to another machine." and let's break down this together
[05:21] <Neo4> what will mean if I do (mydestination = kselax.ru)??? I read here and don't understand anything https://rudd-o.com/linux-and-free-software/setting-up-a-mail-server-using-postfix-in-5-minutes
[05:22] <Neo4> http://pix.toile-libre.org/?img=1516512124.png
[05:22] <Neo4> let's postfix know which domail will delivered?
[05:23] <Neo4> don't know how in practice test it
[05:23] <Neo4> I have real domain kselax.ru
[05:24] <Neo4> if I put it there it will mean postfix will delivered my message from this domain? And what is it on practice, Who can bring a real examples?
[05:24] <Neo4> Just simple examples who he/she consider it must be?
[06:12] <Neo4> what does mean deliver mail direct and indirect?
[06:13] <Neo4> indirect we use relay-host? What is it?
[06:13] <Neo4> What is relay-host?
[06:30] <Neo4> Can we call any domain like FQDN?
[06:30] <Neo4> blabla@gmail.com is it FQDN?
[06:48] <Neo4> What is USE ?
[06:48] <Neo4> USE ( unsolicited commercial email )
[06:48] <Neo4> SPAM in other words
[06:49] <Neo4> send USE )
[06:49] <Neo4> 90% of mails are USE (unsolicited commercial email)s
[06:50] <Neo4> UCE*
[06:51] <Neo4> exists UCE policy restriction
[06:51] <Neo4> my postmaster is admin on my mailserver?
[06:52] <Neo4> he must accept all server errors
[06:57] <Neo4> might be in ubuntu many apps inform or log errors on root + @ + hostname and post server only postmaster + @ + hostname
[06:57] <Neo4> hostname and domainname is differ notions
[06:58] <Neo4> domain server name DNS
[06:58] <Neo4> and hostname is name of your computer
[06:58] <Neo4> what is localhost? is it hostname?
[06:59] <Neo4> what is this ip 127.0.0.1?
[09:29] <Neo1> horde vs squirrelmail vs roundcube?
[09:29] <Neo1> this is equal software?
[09:29] <Neo1> What is we called "webmail"?
[09:30] <Neo1> Webmail is any email client implemented as a web application running on a web server.
[09:30] <Neo1> is it real mail term?
[09:30] <Neo1> webmail any software that is running on mail server
[09:34] <Neo1> I'm wrong
[09:35] <Neo1> webmail is email client running on web server
[09:35] <Neo1> php client
[09:42] <Neo1> webmail apps are squirrelmail, hord and roundcube
[09:43] <Neo1> the most popular is roundcube
