Hi fukawi1, Thanks for your quick reply and clarification. Ricstirato, yours is the best explanation I have seen recently (short, but tells everything) for a mail server! Thank you. So, Friends, please clarify my following doubt too.
Correct me if wrong regarding this scenario....
Server1: exampledomain.com = running Postfix as the SMTP
Server2: imap.exampledomain.com = running Postfix as the SMTP
also Dovecot as the IMAP/MDA.
Now, suppose a mail is sent to firstname.lastname@example.org
from someone, the mail will reach the server exampledomain.com. Now, jane, on her Desktop machine, has outlook express/Thunderbird as email client software and has configured the smtp settings as exampledomain.com and to receive mails she has configured imap.exampledomain.com in her outlookexpress/Thunderbird email client.
In this scenario, how will the imap.exampledomain.com server get the mailbox details of jane whose details are in exampledomain.com:/home/jane/Maildir ( hope I am correct) so that jane can download her Inbox mail from imap.exampledomain.com ?
Thanks a lot again for your valuable information.
