I am running webmin on ubuntu server 10.04lts I have dovecot installed.when I try to check for mail the server unexpectedly terminates the connection. window live mail gives this error, and when i use telnet to try to login and get email it terminates the connection right after i send the "PASS thisismypassword" command.
View 8 RepliesI have been using proftp for about 8 months. After getting the configuration right, it worked perfectly. It is only used intermittently, so I don't know for sure when the problems started, but I suspect it was triggered by a recent OS upgrade to Ubuntu 10.04 (64 bit). I have proftp set up so that TLS is required on both the data and control channels. The problem is that, after successful login, the server seems to be terminating the session because the client (FileZilla) is attempting to renegotiate something (probably the TLS). The client settings didn't change, nor did the server settings.
I have tried switching off the TLSRequired flag, and am then able to establish a non-secure FTP session which works (but that does not meet my requirements). I wondered whether the OS upgrade had somehow invalidated my TLS certificates, but the symptoms don't seem consistent with that cause. The TLS part of my proftpd.conf file is:

View 14 Replies View RelatedI'm using Postgresql 8.4.2-2. I'm trying to remote into my server securely. I figure I could do so with ssh. Apparently I figured correctly, as per, [URL] and [URL] I setup the ssh tunnel. ssh -L 5432:serverip:5432 Then I setup pgadmin3 to connect as follows:
host: localhost
port: 5432
user: postgres
maintenance db: postgres
And I receive the following error:
An error has occurred: Quote: An error has occurred: Error connecting to the server: server closed the connection unexpectedly This probably means the server terminated abnormally before or while processing the request.
I'm not sure what the problem is. I can connect with Code: psql from the cli after connecting to the terminal via ssh. So I know that I'm using the correct password.
was trying to access the server through putty, it immediately closed connection.i tried this a couple of times and still the same problem.

View 3 Replies View RelatedI am running Fedora 10, Postfix and Dovecot I recently changed the password of a user using the 'passwd' command. The problem is that the user can no longer receive their email messages in Thunderbird (Authentication Error). However, they can still login using SquirrelMail and get their mail.
View 2 Replies View RelatedI 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.

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 ?
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.

My question is I've built a new server and now it has Dovecot 2.0.11 & I would like to know if I need to generate a new configuration file or will the above 1.x work in 2.0.11? The configuration file 'dovecot.conf' generated by 2.0.11 is all commented out and I don't know what I need to uncomment / add to the config to get IMAP working.

CentOS 5 box was just setup to replace a crashed old one. I have postfix.admin installed and working, added users (confirmed from mysql command line) and can login using telnet server pop3 with the user information. The problem I am left with is just receiving mail. I have both squirrelmail and roundcube installed, and can also authenticate using both (/var/log/maillog shows);From either webclient I can naturally send mail out and both yahoo and gmail client confirms, yet a reply shows nothing, and nothing ever shows in the maillog. Firewall is shut down but I don't know postfix enough to see how to test, or is something else grabbing the mail.
I can provide anything necessary, just let me know what. As I see it (just so far) Postfix should be the server that answers and receives the mail, dovecot is more the pop/imap the client would use, so I think it's a postfix issue. If so, can I turn up the debugging, etc. but again, I think all mail received should appear in the maillog file 1st as I see the outbound mail go fine!
i had configures sendmail and dovecote in rhel 5.3, as it was working fine with pop3 and imap, but it will not work for pop3s and imaps .the cerificate is chked with mutt it is fine , on client side i use outlook express/Thunderbird . the ports status shown as listening . moreover the certificate was not trusted by the clients. is there any more setting i have to do .

View 3 Replies View RelatedFew days ago we had a server maintenance. The system was shutdown, we fix the CPU fan, and start the system again.

How to find out what happens to my IMAP/dovecot? And anyway to make it run again?
I'm using CentOS 5.5 X64 with dovecot 1.2.16
I have followed the guide for "The Perfect Server - Debian Lenny (Debian 5.0) With BIND & Dovecot [ISPConfig 3]" and all is well, except.
I can send mail (to GMail) from commandline. I can send mail (to GMail) from any of the domains configured in ISPConfig3 through SquirrelMail (how ever terrible that looks, but functions) or IMAP/POP.
but....
I can't receive mail (from GMail) on any of the domains configured in ISPConfig3 in SquirrelMail or IMAP/POP.
I have my domains configured with proper MX records (just like I have them configured at work). I have all ports (80, 143, 110, 25, 22, etc) forwarded on my router that are needed.
I can Telnet to localhost and all checks are fine. I can send and receive from and to local domains on the same server, which makes sense. but
I can't Telnet from any external server to my server behind NAT.
Conclusion:
I figured it MUST be a network/port-forwarding problem as the external Telnet requests fails to my machine on port 25.
Tested my router if it would let met communicate through port 25 and it would.
So it must be my ISP, as I read in different posts.
Question:
Maybe I'm a n00b, but in all other posts the problems were with receiving AND sending.
My ISP responded that port 25 is blocked because of spam issues.
But I can mail (and even spam if I would like to) to external domains while I didn't do anything weird to make that happen.
The only thing I wish for is to receive mails and if you'd ask me, port 25 would be solely for outgoing mails, not for incoming mail deliveries throught MX?
An ISP surely wouldn't disable their customers in having a mail-server for incoming mails, as long as they would send out through their own smtp server to make sure they wouldn't spam the world?
I am able to telnet localhost 143 and telnet ip 143 on localhost.but from outside network am not able to telnet ip 143.

I've read a few similar threads in this forum about dovecot errors but still can't to fix it.
I am running CentOS 5.2 on a server here in my home. It runs Dovecot and Postfix and also serves as a website host for a small website of mine. Everything works fine. POP, SMTP, Webmail, WWW, all works great and has for ages.Here's the issue. I recently reinstalled a clean copy of Windows 7 on a workstation in my home onto a new harddrive(I still have the old drive int he machine so I can boot to it as well). I setup the Windows Live Mail client to send/receive mail with my mail/web server. However, it won't connect to the POP server on my server machine.Here's the kicker. If I boot to the old harddrive that is running Windows 7, it connects fine to my mailserver and can send/receive just fine. I've checked, rechecked and rechecked and all mail settings on the mail clients on both drives are identical.
Note: The installations of Windows 7 on both drives is identical. Same computer name/ same credentials, same IP, etc. However, as I stated, I can send/receive email with my server if I boot to my old drive, but if I boot to my new drive, I cannot send/receive.
I just want to create virtual postfix users using static external file, without using dovecot as MDA or mysql db.
