CentOS 5 :: Dovecot/pop3 Email Service Following File System Restoration?
Sep 11, 2009
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.

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:
The following actions will resolve these dependencies:

I would like to change an email account from POP3 to IMAP on an ISPConfig 2 system, I can see that the IMAP and POP3 process are both running.
I have the Maildir check box ticked for the server
Is there anything else I need to do, or is it just a case of changing the mail client from expecting POP3 to expecting IMAP?

Having my Diploma Final Project on setting up a virtual mail server within Local Area Network (LAN) only. I had follow this how-to [URL] and complete up to squirrealmail web mail. I added two new user to try on sending and receiving mail. It works. I run CentOS on VMplayer. I using my laptop to do all the stuff, the laptop default OS is windows 7, I install VM player on it and run CentOS inside the VM Player.
I want to do testing on Windows 7 side by installing Thunderbird email client program, I want to connect to mail server with SMTP, IMAP/POP3 using the email service. I have problem while setting up user account on Thunderbird, Thunderbird seems like cannot detect my CentOS mail server. How? Do I have to do any other configuration on CentOS? Any DNS? Port number for IMAP, POP3 or SMTP?

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 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'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 set up a mail server on centos5 using sendmail and dovecot, and eventually spamassassin and some antivirus filter as well. I'd also like to get the proper secure auth mechanism set up at some point too. But for starters, I've been having a lot of difficulty trying to even connect to the mail server from a client computer in the local network. I installed Eudora on the client and after some tweaking in dovecot I was able to connect to the mail server, but then when I try to send an email I get a "connection refused" error, with nothing being logged on the server that I can see.
The last time I set up a mail server was Fedora Core 2, so the configuration files have changed a bit to say the least, and I can't really refer back to those to set up this new server. Does anybody know of a good step-by-step doc on getting the mail server going? I've read the man pages and other various readme's, but these really only list out the available options with no really good explanation of what needs to be done to get the mail server going. If there isn't a full write-up on how to do this, I'll put something together when I'm finished so others can use it in the future.

My actual mail is via pop3 from verizon. What I've done so far is just pull my pop3 mail onto my main machine at my house. But I'm finding I'd rather have a single imap server on my network so then all my machines could see the same mail.
I don't really want the imap server to poll verizon for mail, I just want the imap server to check pop3 mail at verizon only when one of my mail apps checks into it to look for mail.

I want to retrieve emails from my POP3 servers to my home server. But from there, I want to be able to access them via IMAP from my other computers, i.e. desktop, laptop, phone. And then of course I want to be able to send emails from said devices via IMAP to my home server which POP3's them out to my mail servers. Basically, I have a few POP3 accounts with various hosts and I want to conveniently interact with them from lots of devices using my preferred software (i.e. Mutt, or Thunderbird on my Windows boxes). My home server is Ubuntu Server if that's relevant.

I have an email server configured with postfix, dovecot, saslauthd and squirrelmail. It works great. In fact I'd even say it works too well: in squirrelmail, I can configure any sender address and my server will accept it. Message will be sent, wether the sender's address is [URL] or [URL]. Is there any way of limiting it in such way that only [URL] is accepted as sender's address?

In the config file, I have :
protocols = imap pops imaps pop3s

I have a very basic install of dovecot and postfix on the latest version of Ubuntu server. This is an internal only email server with internal only DNS. I can send email via clients and check said emails via the command line when logged in as the appropriate user. I cannot for the life of me check said emails via SquirrelMail on the server nor using IMAP clients. I have no idea where to look and I can't find a basic tutorial for the life of me. Where should I start?
