Debian Configuration :: Install Courier-pop3 And Dovecot-pop3 Simultaneously ?
Apr 16, 2010
For long-term migration from courier to dovecot I would like to install courier-pop and dovecot-pop3d simultaneously. Aptitude offers me to install one, by removing the other, only. Can this be done without creating problems for the package manager and future upgrades? And why if not?
The following NEW packages will be installed:

I have so far: installed and configured postfix, installed courier, installed MySQL and SASL. mostly following a guide on [URL]
When I want to login via POP3 with a user from the MySQL database, authentication fails.
The mail.log file contains the followiung error:
Nov 25 18:47:55 asmahan pop3d: Disconnected, ip=[::ffff:10.11.39.33]
Nov 25 18:48:05 asmahan pop3d: Connection, ip=[::ffff:10.11.39.33]
Nov 25 18:48:16 asmahan pop3d: LOGIN FAILED, user=john, ip=[::ffff:10.11.39.33]
The problem only occurs when I try to login via POP3. I can send emails via SMTP using the same account without any problems.

I believe I have everything but this setup, as when I use my Outlook's Test Account Setting, it's able to do the following:
1) Send a test e-mail
2) Connect to POP3
3) See the actual test e-mail at /var/spool/mail/<username>
However, the Test Account Setting wasn't able to authenticate to POP3. I then do the following:
1) Start up Command Prompt.
2) Execute "telnet <server IP> 110". It gives me "+OK Dovecot ready".
3) Type "user <username>"
4) Type "pass <password>". It gives me "-ERR Authentication failed".
Then I searched around and found this. However, I'm not sure if I am able to make any sense out of it.
My CentOS 5.5 is setup with the following standard files:
/etc/passwd (password field contains the character "x")
/etc/shadow (examining this reveals it's using MD5 has as the password field begins with $1$)
So how should I set my /etc/dovecot.conf? I think it's this file I need to setup to enable POP3 authentication?

I have recently set up a mail system using Postfix, Dovecot, Spamassasin, ClamAV and atMail - I'm new at this, so proud of myself to have gotten this far. I have required secure authetication for both sending through SMTP and access via POP3 and IMAP. All seems to work properly. I have tested POP3 with KMail and Evolution and everything works great. The only problem is I cannot get Outlook 2007 to authenticate for POP3. I can send through SMTP with secure authentication from Outlook, but no matter what I try I cannot get it to authenticate for POP3 access. Checking SPA in Outlook causes it to repeatedly ask for credentials which it does not accept, while un-checking it causes the client to be immediately rejected by the server.
I have turned on all the various relevant client work-around options in Dovecot and Postfix (that I am aware of) and I have hunted through the web to see what I can find, but no luck.
Besides using the listed client work-arounds in the Dovecot config file, can anyone shed light on what else I might need to do to get Outlook 07 working with POP3?

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'm trying to configure dovecot in RHEL6, but seems system won't accept local user login. I've already disabled pam. 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 have recently set up a mail server running dovecot and everything is fine. However, I now want to retrieve the contents of 2 pop mail boxes and insert them into the IMAP structure under dovecot. I need to check for spam and sort them according to sender and recipient.
What is my best software option for retrieving the mail?

recently I've replaced an old windows mailserver with a new one running 10.04 LTS (postfix - dovecot) but I got a strange problem with MS Outlook 2003 and 2007 on Win XP. These MUAs receive new messages extremely slow. Some of messages are received repeatedly. All I found in /var/log/mail.log is login and then (after 1 minute) disconnection for inactivity. No errors.:
Jul 11 10:36:51 dovecot: pop3-login: Login: user=(user@domain.org), method=NTLM, rip=xxx.xxx.xxx.xxx, lip=xxx.xxx.xxx.xxx Jul 11 10:37:07 dovecot: POP3(user@domain.org): Disconnected for inactivity top=0/0, retr=1/5434, del=0/12, size=954793 nothing more. And outlooks wait and wait reporting "receiving". What they are waiting for? Is there something dovecot should send them?
At the same time Mozilla Thunderbird and Opera Mail on the same network with the same setup don't have any problems. I just don't get it. Does anyone know what to do to get it work please?

I am trying to prepare procedures for email restoration following a file system loss that contained user Maildir directories. Assuming that my most recent backup is earlier than the last time that many users received and downloaded email, the restored mail directories will not contain messages that were previously received and downloaded to clients following the backup and preceding the crash. This is not a problem in itself, however, it does appear to cause problems for the email clients.
My desire would be for email clients (outlook, outlook express, thunderbird) to properly recognize the messages that currently exist on the server, ignore previously downloaded messages and download newly arriving messages.The behavior that I am seeing is that the email client fails to recognize that any new messages exist and fails to download any messages at all. By removing the dovecot.index... files and the uidlist file, the clients will download ALL messages that are present in the "new" and "cur" directories even if previously downloaded. This is also an undesirable outcome.

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 am trying to install Mozilla Thunderbird email client. When I configure this program, it defaults to IMAP4-type incoming mail server (Port 143) instead of POP3 (Port 110) which my ISP uses. I did not see POP3 anywhere in the available dialog boxes. Is there any way to get Thunderbird to use POP3 in opensuse 11.2 Gnome Edition?

I'm a newbie here but I have a question on how to make the connection between webmin and thunderbird via POP3. I have webmin set up and it is able to send and receive mail via webmin but when I enter the account details in thunderbird it cant find the settings for my mail account. I'm not exactly sure where I need to go in webmin to set it up to allow a connection from a client to allow the downloading of mail to the client. Would simply prefer to go to thunderbird to send and receive mail as opposed to logging into webmin then going to my mail.

Recently while upgrading my email environment which was on postfix, POP and IMAP, server was crashed. We had to rebuild the new server and managed to restore everything from database but the during that process somehow users were not able to login using their old password hence we had to reset the password for every user manually. There were arnd 2500 users configured on the system. Now I have been asked not to put the newly built system into the production unless and until all the POP users and passwords are verified.I m thinking to write the bash script by which I can telnet to my POP server and then provide username and password to see the response

According to RFC 1939: "POP3 is not intended to provide extensive manipulation operations of mail on the server; normally, mail is downloaded and then deleted." However most of the mail clients have that option "Leave messages on server" after they have been downloaded. How is it done?
I tried sniffing mail traffic with Wireshark, but the only POP3 provider I have is Gmail and its POP3 access is SSL secured, so I was unable to gather any info from this... I tried downloading sources of Thunderbird and Evolution and checked what are they doing with "leaving messages", but it seems my C++ skills are not enough - I was unable to understand what is happening when "leaving"...
Suggest me some POP3 provider, that is providing unsecured POP3 access, so I could try again reverse engineering with Wireshark?

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 first seriously tried to switch to Ubuntu. I now find myself very rarely booting into Windows XP, and all the apps I need to use have free replacements.However, after porting about 15-20 years worth of email from Outlook (via Thunderbird) into Evolution, I'm finding Evo's performance has gone down the toilet.It was snappy to start with, but over time has got slower. I regularly get long waits as it displays notes that it is retrieving message number <whatever>.
I'm using POP3/SMTP for most email (I've a low-usage IMAP account with gmx.com too), but it seems like some sort of issue where I'd want to optimise or "defragment" my local mail store.Has anyone any ideas or suggestions on this?My ~/.evolution/mail folder contains about 2.5Gb if that's any help.This is with 9.10 Ubuntu; I have done some basic tuning on the setup, but not a lot.

I'm run 10.10 desktop x64 and when I start setting up an account in thunerbird and enter name, email address and password in the first window and go on to the next next that window flashes pop and imap very quickly before stopping with a showing of imap. There is no edit button and I have not been able to find out how to set the protocol to pop3. Is there and error? Or am I missing something. I like thunderbird and would like to continue using it but my email providers only support pop3. I'm writing to this list because I'm thinking the problem may be specific to my version of ubuntu but I'm not sure.

I'm trying to set up my gmail account with Evolution. I am trying to set up a mail client where -
1) All the mails are stored locally, so that I can work offline. When I reconnect, the client (Evolution) syncs with the server - sends emails and updates any changes.
2) All the labels/folder system to be respected and retained.
After struggling with various sites that argued Pop3 and IMAP (numerous blogs and google searches), I came across this conclusion (pls correct them if they are wrong)-
1) Pop3 allows mails to be stored locally, but will not break them up into folders.
2) IMAP will allow the folder system, but will only store the headers of mail on the local server, and the content will be downloaded as per request.
1) Will Pop3 access allow syncing between the local version and the server version? For instance, a mail read in Evolution should be marked as read when I sign into the web-interface as well.(I can always create a filter/rule that replicates gmail filters)
2) Will IMAP allow me to store all mail locally (isn't this exactly what IMAP is not!)? The combination of imap-gmail-evolution was not so successful when I tried it out - too slow!
PS: I would prefer Evolution over Thunderbird so that I can integrate the Calendar. However, if ThunderBird is the easiest solution, then it's fine too...

I'm trying to connect to Gmail to pull my emails from the Gmail site, via the IMAP/POP3 access server. However, I can't seem to connect to the server when in Ubuntu code...
And it hangs here indefinitely. However, if I reboot my PC into Windows, it connects fine. I've turned off UFW so I would expect the connection to work. I've also been able to POP3 into other servers, so it seems to be something specific to the gmail IP.
Anyone else had the same problem or know how I can debug/fix this?

I have a mail server running RHEL, with postfix, dovecot, etc. I installed Fail2ban and this works wonders against SSH brute force attacks. It'll ban an IP address for a period of time if it unsuccessfully attempts to log on 3 times within, say a minute. I was wondering if it can be as effective with pop3 attacks. If it is, how can I get it done?

My server listens to POP3/IMAP requests. Some users have configured their mailers with high checking frequencies, say once every minute, such that the system logs are full of entries with no significance at all.I'd like to ask if there is a way to limit the per IP frequency of POP3/IMAP access ?I'm using "xinetd" to wrap the "ipop3d" and "imapd" which come with the Alpine package.
