I'm preparing my new
Sendmail mail server with pop3s + smtps where user
SMTPS is obsolete since a
couple of years. Use SMTP/STARTTLS instead
over the submission port.
I know, I used both ports (SMTP over SSL port 465, SMTP/STARTTLS port 587) for mail- client compatibility. Do you suggest to use only port 25 with SMTP/STARTTLS ?
authentication occurs through Microsoft Active Directory by Winbind
daemon. OS is Centos 6.4 and Sendmail is 8.14
Mailboxes will be in this
server but how to create them !??!
That totally depends on the choice and
configuration of the mail storage
and access server. Sendmail is an MTA, it
does not know about
"mailboxes". It knows - if properly configured - about
destination mail
addresses it is responsible for to hand over to an MDA/LDA.
My MDA/LDA is procmail but neither .forward and nor .procmailrc file exist.
There is no filter/rule .. define(`PROCMAIL_MAILER_PATH',`/usr/bin/procmail') dnl FEATURE(local_procmail,`',`procmail -t -Y -a $h -d $u')dnl MAILER(procmail) dnl ..
It's necessary to add user by 'useradd' command into /etc/passwd
or It's
only necessary add new entry in '/etc/aliases' file for every AD
user
like in following example ?!
That depends on the chosen mail
storage and access server configuration.
I don’t understand server behavior (where no configuration procmail files exist) when MTA receives email message to delivery to mailbox which stays on the same server. How does system know what mailbox file to delivery to ? What link among ‘AD user account’ and ‘mailbox filename’. In my case I had to create new recipient user by ‘adduser’ command, otherwise my system said ‘user unknown’. I remember my user is on AD services on another server which run Windows OS.

The part of your setup
which will server for POP3S. CentOS 6 comes with
cyrus-imapd and dovecot.
Read about them and make a choice. Maybe you
already know one of them good
enough.
I chose Dovecot to use only POP3s service.
POP3s the account
name (AD user), which I'll use to access my mailbox by pop3s,
must have the
same name of mailbox file ?
No.
According to previous example:
if I
wanted to download email of 'mark.landers@example.com', in my client
I
shall have to type 'marklanders' with its password, so my requirement is
to
have this mailbox file into my mail server: <mail path>/<user> for
example: /var/spool/mail/marklanders
First you will have to decide whether
you will run a single domain setup
or to provide multiple domains where
mailbox accout foo@example.com
isn't neccessarily for the same user as
foo@example.org or foo@bar.com.
Single domain
