Server :: Error: Connection Dropped By IMAP With Dovecot
Apr 19, 2011
I am running SquirrelMail version 1.4.8-5.el5.centos.10 on a CentOS 5.6 64-bit distribution with MailScanner 4.83.4, Sendmail 8.13.8/8.13.8, and Dovecot 1.0.7 release. One user is having problems connecting via the SquirrelMail interface to his e-mail. Whenever he tries to connect, he gets the following error message:
Quote:
Error: Connection dropped by IMAP server with dovecot
I have tested another user account, and that user is able to connect without issue. I confirmed the presence of dovecot.index, dovecot.index.cache, and dovecot.index.log files in the user's <HOME DIR>/mail/.imap/INBOX folder. The /var/log/maillog files do not list any apparent error messages with SquirrelMail.

I'm running Dovecot version dovecot-1.0.7 on CentOS 5.4. I'm trying to create subfolders and I can't. I've tried Mac's mail application and Thunderbird; they both come up with an error, basically saying that the server doesn't support level one folders(subfolders). Squirrelmail can't create subfolders neither. I did some reading and thought that perhaps the problem lies in the /etc/dovecot.conf file; specifically with the "mail_location" directive. I currently don't have that directive active which means Dovecot uses defaults settings: saving users' mail in the %u/mail folder. Is there any way to configure Dovecot to use subfolders?

Sometimes during bootup I get the following error:Starting Dovecot Imap: Fatal: listen(995) failed: Address already in useI tried to figure out what I could with the command lsof -i :995 and this was my output:COMMAND PID USER FD TYPE DEVICE SIZE NODE NAMErpc.mount 2936 root 7u IPv4 9201 TCP *:pop3s (LISTEN)When the system boots without the dovecot error the output of losof -i :995 is as follows:

Does anyone know if there are only personal preferences between the two IMAP servers or does one of a slight advantage over the other? I've used Dovecot only in the past but my package manager loads tons of MySQL libraries with Dovecot which is a problem since that's not authorized on my server right now. I can either install it from source or try another application like Courier.

i have some problems to start my dovecot server. I tried to install it from webmin using "un-used modules" but it was allways the same error: "E: Unable to locate package dovecot-pop3d".When I tried to install it from console using the commands: apt-get install dovecot-imapd dovecot-pop3d dovecot-common - and there are no problems with dovecot-imapd and dovecot-common, but still the same error with dovecot-pop3d. After command: service dovecot status: could not access PID file for dovecot ... failed!
After try to start dovecot with comand "dovecot": Error: mail_executable: Can't use /usr/lib/dovecot/pop3: No such file or directoryFatal: Invalid configuration in /etc/dovecot/dovecot.confI've read a few similar threads in this forum about dovecot errors but still can't to fix it.

I've tried mutt -f imap://xxxx, and Thunderbird to connect as imap and pop3, but both failed, seems dovecot won't accept the password of the login user.the dovecot info log as, Jul 03 20:48:42 imap-login: Info: Disconnected: Too many invalid commands (no auth attempts): rip=192.168.1.3, lip=192.168.1.3, mpid=0, secured

I'm somewhat familiar with Linux and became pretty decent at installing and configuring packages in Ubuntu. One of the things I was able to do with my tinkering was set up a functioning imap and pop3 mail server using dovecot-postfix. Now I'm experimenting with Slackware to get the feel of another distro, and I noticed that the mail server packages were already installed. On my client computer they can pick up that I have users configured and my mx record is working.
However it is failing to send mail saying that it is failing to relay the e-mail message and that the server responded 5.7.1 which was a problem that I was having in Ubuntu when first configuring the mail server. The fix was to edit the postfix.conf file and adding the localhost name of my server. Does anybody know of the file that I need to edit to make it possible to relay my messages with both pop3 and imap.

I just setup dovecot to use imap. I'm using the same cert and key that I'm using on Postfix smtp over ssl. It's a self signed cert. After running this
Code:
openssl s_client -starttls imap -connect localhost:993
I get this
Code:
CONNECTED(00000003)

I have a problem connecting my roundcube to my imap server.
So, here it is : I have a working imap server (dovecot), installed following the guide provided here [url]. I can successfully telnet it, or ssl it (from localhost or from another ip of my local network). I can even use my thunderbird from another local computer. Well, for me it is working fine.
Then I installed roundcube (0.3.1-3) with synaptic, but I cannot connect to my localhost imap server.
I have set auth as plain ($rcmail_config['imap_auth_type'] = 'plain';)
Looking in my dovecot log, i see two different behaviour. One is when it seems correct, and roundcube log in imap server, but is disconnect immediately :
Second is when server is refusing the password :
I am working with a plain text passwd, with no encryption at all. Does roundcube encrypt the password I type before to sent it to imap ?
I cannot explain the first behaviour, when roundcube sometimes managed to connect but disconnect immediately. I manage ONE time to reach my mailboxes, but i don't know how, and this never happens again.

I am having some trouble finding the information i need, here is what i am trying to accomplish.
1. Download POP email messages from cody@clearsky.net.au using fetchmail and assigning them to account "cody"
2. Connect and view the emails via IMAP using dovecot server logging in using "cody"
So far i have the fetchmail part working fine, but i cannot see any emails in the inbox. The messages are going thru however as they are visable in MUTT. i have edited my /etc/dovecot/dovecot.conf to change the mail directories, but no luck

Just upgraded to Ubuntu 11.04 - from 10.10, and now experiencing connection problems with Evolution connecting to my IMAP Microsoft Mail Server. This was working, I was successfully receiving and sending mail via my IMAP setup in Evolution. Since the upgrade to 11.04, it stopped working with the error: "Error while Refreshing folder "INBOX". You must be working online to complete this operation." I check to see if it's in online mode, and it is. I set evolution to work in offline mode. Then I set it back to "online mode" and I get the error: "Error while Reconnecting to 'IMAP Server mail.foo.blah.de.bla". Could not connect to mail.foo.blah.de.bla: Connection Refused"

I am having the following error on my logs.
[code]...
I used mail_uid and mail_gid in dovecot.conf to set the permissions, I'm not using local system accounts, instead accounts specified in MySQL. I can dump all the output of doveconf if requested.

I've had Dovecot up and running for months now without any problems whatsoever. Came in this morning and suddenly I can't connect to it. Thunderbird hangs with "Checking mail server capabilities..." and Windows Mail spits out the following error:
Code:
Cannot establish TLS with IMAP server 10.0.0.2:143, SSL_connect error 336142597
Configuration:
Account: Blah
Server: foo
User name: whatever
[code]....
Thing is, I'm not using TLS/SSL and have changed exactly nothing since the server was set up. I've tried having the mail clients use SSL/TLS in response to the above error, but that changed nothing.

To configure webmail in linux5, I�ve followed below procedures:
-Squirrelmail-1.4.2.tar.gz and unzipped under the folder /var/www/html
-cd squirrelmail-1.4.2
-cd config
-within this directory, ./conf.pl
-From main menu, I did choose 2 for domain (i.e. arafapparels.com). This is my official domain
-Then save and exit
-For IMAP setting, I did choose D
-Selected uw and save, then exit
-Then from command line, I wrote chown �R apache.apache /var/www/html/data (I created folder data in the above path)
-I created a folder named as attach to keep attachment in /var/www/html i.e. /var/www/html/attach
-Then typed grep �R apache /var/www/html/attach
-Then typed chmod 730 /var/www/html/mail/attach (Here squirrelmail-1.4.2 directory has been moved to mail directory)
-Then from web browser/Internet explorer, I typed http://localhost/mail/
-Here Username & Password appears. Previously I have created username.
-But when put Username & Password, below error message displays
Error connecting to IMAP server: localhost
13: Permission denied
But I gave permission by chmod 777 /var/www/html/mail and by using 555 but no result.

I have discovered that my ISP drops down my mobile broadband connection specially at night. It is a very annoying fact because this type of net access is not cheap at all. I am using Fedora 14 newest core. I am able to configure Network Manager to automatically connect, but... this option does not solve the redialing issue.
Is there any way to set up redialing a dropped mobile broadband connection? A perl or python script, may be?

I have a Netgear DG834 ADSL router (v3) which I have used for a couple of years. Prior to that I had a v2 of the same router, but upgraded for the one that supports ADSL 2+ (here in the UK).
Recently I have been having problems with the connection often being dropped, and when I access 192.168.0.1 for the router admin page, when it is not working I get no IP address listed for that of the ISP's server, and sometimes as well the upstream and downstream speeds are listed as 0 kbps.
Usually this was resolved by rebooting the router.
However, for the last couple of days, when using Ubuntu 9.04, the page of the router at 192.168.0.1 will not load. I have tried numerous different browsers, and none of them will give the router admin page.
When I tried booting from a live CD of Fedora 13, the router admin page came up just fine, no problems (although still not getting a proper connection to the Internet).
I was going to try to use the older router I had, but so far, as I cannot access the router admin page in Ubuntu, I have not done so (not had the time, and now I am at work posting this).
So there must be a problem in Ubuntu that is preventing it showing the router's admin page. The Network connection details show that the router has given the PC an IP address of 192.168.0.6 and the DNS servers are listed, so I know that Ubuntu is talking to the router, but it is not allowing me to access its settings in any way.

Using Thunderbird 3.0.6 under OpenSuse 11.2 worked without a problem. I have installed Opensuse 11.3 (freshly on a new partition) and I found that Thunderbird 3.0.6 is NOT connection with the same server. I used the old configuration (~/.thunderbird) from the 11.2 partition first to no avail, later remove the ~/.thunderbird link to make a clean start with Thunderbird, also to no avail.
I see some traffic coming on the server from my new 11.3 machine, but the courier IMAP server doe not respond at all.
So, same configuration, same Thunderbird version, difference is only 11.3 versus 11.2.
I now returned to 11.2 back again without any changes.

I am running an Ubuntu Server on a VirtualBox VM running on my windows machine. So I've created a self-signed certificate using the following tutorial: [URL]
From this tutorial I'm left with 3 files:
server.key
server.csr
server.crt
Then I found this very similar tutorial that has an extra bit on installing the certificates in apache: [URL] So I followed it's instructions which boil down to this:
[Code]...
So I'm thinking this should work now. However in Chrome I get: SSL connection error Unable to make a secure connection to the server. This may be a problem with the server, or it may be requiring a client authentication certificate that you don't have. Error 107 (net::ERR_SSL_PROTOCOL_ERROR): SSL protocol error. IE8 gives me a typical "Internet Explorer cannot display the webpage" Note that [URL] fails while [URL] works fine, so it's definitely something in my ssl setup I'm thinking.

I have installed a linux server in my office to run 16 machines. Its main use will be a internal mail server but will be also running websites.
I have installed Ubuntu 9.10 server x64 and have got apache running.
I am looking for the simplest more robust solution for smtp, pop3 and imap. I have only ever used qmail before and found it a pain to configure and its getting old so I though I should probably try something new. I have not much experience with running pop3 or imap on linux so would love a suggestion on that.

I've been running Courier IMAP for many years now, but when I added gmail's IMAP to my Outlook I noticed something interesting: when you delete a message, it gets thrown into the trash instantly.
With Courier IMAP (or any other IMAP server, for that matter), when you delete, it first marks it for deletion. Then after you Purge Deleted Messages it either gets rid of them or moves them to trash.
Is there a way to implement this in Courier IMAP?

I'm looking for a method to sync my calendars on my IMAP server with both my Thunderbird/Lightning any my Blackberry. I found "IMAP Calendar Proxy" here recently, but it has been inactive for 5 years. I've seen people suggesting the use of services like Plaxo and such, but I don't like the idea of a third party messing with my calendars and contacts. Also, I've had to remove several viruses from computers with Plaxo, and I'm not sure if it in itself is a virus or not..... It certainly is a thorn in my side as is. This is for my personal IMAP server, so I'd prefer a free solution even if it is more difficult to install than a paid version. I mainly need it to just sync my calendar to my Blackberry and Thunderbird and couldn't care less about the contacts.
I've been Googling for things for quite some time now, and haven't really found anything that says that it will work with Blackberry and Thunderbird. They really only give a sense of maybe with nothing really defined. I can put on an Ubuntu server to sync everything? I don't want to leave my computer on all the time, and RIM has yet to come out with something decent to sync Blackberries and Thunderbird properly as far as I know.

I am merely trying to change the port for my ssh server.However it isn't changing.I edited my ssh_config file to:
Code:
# This is the ssh client system-wide configuration file. See
# ssh_config(5) for more information. This file provides defaults for[code]...
When i try to connect to my server via port 443 i get a connection refused error. However when i try to connect via port 22 it connects. Since that didn't work, i tried restarting the entire server.To restate, i changed the config file and restarted ssh then the computer, however the port didn't change.Ohh and yes my router is set to port forwarding on port 443, though it doesn't matter since I'm inside the network.
