[Dovecot] [Urgent] Email Retrieval from remote servers doesn't use Dovecot
Dovecot Version:
2.0.13
Output of "dovecot -n":

Objective:
We need to download emails from remote server using Dovecot and thunderbird. Our objective is to store emails in maildir or mbox format, and process them as part of our research project.
Problem:
Dovecot works for localhost, but not for remote servers. How do I know?
Because thunderbird downloads emails in its default location (specified in
settings) and not in maildir or mbox folders. If I send mail to
<user>@

Commentary:
As is obvious from the commands and output listed above that dovecot is running, listening on 110 and 143 - but only for localhost. When I try to telnet mail.ut.ee 110/143 I get to see IMAP4/POP3 ready rather than Dovecot ready.
Queries
Shouldn't I get "Dovecot ready" message for remote servers as well? It is an MRA and we shouldn't be required to install it on remote servers, right? What should I do to make dovecot work for remote servers?
Hi,
What makes you think that e-mail retrieval from remote servers should be over Dovecot? Is 193.40.5.156 running Dovecot that it should say "Dovecot ready." ?
I think what you need fetchmail or getmail. Dovecot is a MTA, not a MRA.
Best, Kerem

It seems obvious that mail.ut.ee/193.40.5.156 do not address the Dovecot host in question, but another host. Otherwise you would see "Dovecot ready" across the board. Please show:

It looks like you want to get e-mail from someone else's mail server and store it in maildir or mbox format on your server.
You could do this by pulling the mail from someone else's mailserver using Thunderbird, then using Thunderbird to move it across to an account configured to access your server by IMAP.
Alternatively you could do it by retrieving the mail using "fetchmail" on your server and have it delivered to an address on your server. This would have the benefit of being more reliable and more scriptable.

That is the expected behaviour. You installed Dovecot on your server, ergo it is only on your server. Installing Dovecot on your server doesn't magically install and configure it on other people's servers.
Queries

No; you only installed it on your server.
It is an MRA and we shouldn't be required to install it on remote servers, right?
If, by "MRA", you mean "Mail Retrieval Agent", then no, Dovecot is not an MRA.
What should I do to make dovecot work for remote servers?
Dovecot, in and of itself, won't "work for remote servers".
You may be able to do what I think you want to do by pulling the mail from the remote server on to your server.
You may want to look into "fetchmail".
