Courier-imap pop3d fail to deliver message to a POP client on first attempt. On the second attempt its able to download the messages and no problems. Not sure what could be causing that problem. Are there any tools that are used with courier-imap mailboxes for fixing corrupted mailboxes?
View 2 RepliesI have a problem with an account. The client connects and starts getting his mails, like this:

I have just got a Dedicated Server and everything is running fine except the mail (outbound). Some times it sends mail fine but most of the time I am getting a bounce back stating the address cannot be found (Which I know is untrue because it is my main email address). It is not only happening on my address but a few others I have checked as well.
Here is what I get when I get a bounce back
==========================================
Could not deliver message to the following recipient(s): ......
I have a mail account hosted in a VPS with cpanel and SquirrelMail as webmail client.
It has thousands of mail files. SquirrelMail got very slow, because courier-imap is very slow sorting files and authenticating users.
I've heard that Dovecot is much faster than courier...
Does anyone have replaced courier by dovecot in cPanel installations? is it a good idea?
Basically a client has been getting really bad email problems with their email. They keep getting the standard qmail msg back from several emails. I originally thought this msg was being returned as it was an invalid receipients address, but they are assuring me that this is not the case?
Anyway the basic msg they are getting is:
Hi. This is the qmail-send program at p16489287.pureserver.info.
I'm afraid I wasn't able to deliver your message to the following addresses.
This is a permanent error; I've given up. Sorry it didn't work out ....
yesterday i setup my first vps system and now its hosting 2 forums of my. Thing is in evry 10 mints Mysql & courier-imap are restarting..? I know this from the lxadmin alert email. So is it normal or is it a problem in my configuration..? Im running cent os 5 now. And i also check the log.. there is entry like below in it..

Hopefully I'm posting this in the correct area. Our server runs CentOS 4.4 on x86_64 arch.
So basically everything was going rather smoothly...
Problems began to arise at the point where I finished installing/configuring SquirrelMail. Upon logging in, I saw this:
[see attachment]
Ok, so I checked maillog and saw:
Feb 11 13:50:46 zeus imapd: LOGIN, user=alex, ip=[::ffff:127.0.0.1], protocol=IMAP
Feb 11 13:50:47 zeus imapd: Failed to connect to socket /tmp/fam--
Feb 11 13:50:47 zeus imapd: Failed to create cache file: maildirwatch (alex)
Feb 11 13:50:47 zeus imapd: Error: Input/output error
Feb 11 13:50:47 zeus imapd: Check for proper operation and configuration
Feb 11 13:50:47 zeus imapd: of the File Access Monitor daemon (famd).
Feb 11 13:50:47 zeus imapd: DISCONNECTED, user=alex, ip=[::ffff:127.0.0.1], headers=0, body=0, rcvd=21, sent=57, time=1
So I did some searching and determined it was a problem with Courier-IMAP being compiled with File Alteration Monitor support and famd not running (I built RPM directly from source tarball without any customization whatsoever per the instructions on the Courier website).
I found some possible solutions to be:
1) Install and run fam and be sure portmapper is running as well (problem being is that fam has since been replaced by gamin on CentOS, which is installed properly on my system).
2) Do a source install of Courier-IMAP and --disable-fam
Ok, so route 1 went like this: I uninstalled gamin, found fam-2.6.8, installed it, started it manually, made sure portmapper was running and tried again. This time, I still got the same errors in SquirrelMail, but the errors in maillog didn't show up. However, shortly after the page loaded, the famd process I had started manually promptly ended without my intervention. Ok, onto trying #2.
Route 2 went like this: reinstalled gamin, then I tried building a custom RPM by manually configuring with --disable-fam and then using rpmbuild -bc --short-circuit and rpmbuild -bi --short-circuit. That didn't change anything at all, I still had the same errors both with SquirrelMail and in maillog. Then I said ok, I'll just do a complete source install. ./configure --disable-fam && make && make install. Manually started that server, tried again, same deal, both errors.
So I've got problems. Either with Courier-IMAP, SquirrelMail, or both. The other daemons seem to run fine, I just mentioned them in case of the possibility of some kind of (unknown to me) conflict.
If you need to see any of my configs, let me know...any information greatly appreciated...I'm desperate.
I'm trying to find Courier IMAP config: /etc/courier/imapd
Because i would like to edit the parameters for the trash folder (see qoute and link below)
The file on my server is not there. I did some grep and locate commands and was unable to find it.
##NAME: IMAP_EMPTYTRASH:0
#
# The following setting is optional, and causes messages from the given
# folder to be automatically deleted after the given number of days.
# IMAP_EMPTYTRASH is a comma-separated list of folder:days. The default
# setting, below, purges 7 day old messages from the Trash folder.
# Another useful setting would be:
#
# IMAP_EMPTYTRASH=Trash:7,Sent:30

any hints for EXIM reject E-mail trying to be sent to an non-existent account on a domain hosted by me? I think the default configuration is to accept the E-mails and try to deliver, then it will fail and an E-mail will be sent to the sender
but many times the sender is fake (spammer) and this message will rest on queue for some days...
I was thinking on some filter like
"if ((!exist account@domain) && (!catchall domain)) reject"
but I don't know how to set something like that on EXIM

Has anyone successfully configured sendmail to work with vm-pop3d under FReeBSD?
View 1 Replies View RelatedI'm having trouble with horde it is giving me the following error:
Auth_imap: Required IMAP extension not found.
Now I pretty much know why that error is coming up I'm missing the IMAP module. What I don't understand is if it was their before why is it gone now. The last thing I did on the server was upgrade Perl.
I would like to get rid of this error but I'm afraid the only solutions will wipe my current setup. If of course their is a way to fix this error without ruining my current setup that would be a lot more useful
The main thing I want to do is retrieve an address book from the horde server. How would I go about finding where the address book is stored through the command line.
Thanks ahead of time for the help.
Hello, I have a problem with the vm-pop3d service I have set the option (--daemon=30) to 30 and the time out to 900 in /etc/init.d/vm-pop3d but still is not enough, many connections to the pop3 server are dropped is like the connections remains active (persistent) because when I try to restart the server I get a failed error on shutting down and still get the timeout error with outlook, I need to kill all the vm-pop3d process a then restart it in order to work but 10 or 15 minutes later I get the timeout error again, so I don't know why is failing continuously and why don't shutdown properly when restarting the service.
[root@server ~]# service vm-pop3d restart

my mail server stops authenticating users. When they try to check messages they get the login screen in their mail clients again and again. I have to go to the server and restart saslauth, mysqld and postfix.
I'm getting the following warning when restarting MySQL:
070403 13:53:09 mysqld started

Also, my maillogs is showing these errors:
Apr 3 13:24:47 mail1 pop3d: authentication error: Input/output error
Apr 3 13:30:25 mail1 pop3d: authentication error: Input/output error
Apr 3 13:30:28 mail1 pop3d: authentication error: Input/output error
Apr 3 13:30:29 mail1 pop3d: authentication error: Input/output error
Do I have to increase connections on my.cnf? I think 2548 is enough for the amount of user I have which is less than 100 users.
I need to determine which mail server is better so i can know what to install as default on future servers.
View 9 Replies View Relatedi have cpanel with 512 meg ram.
i need fast mail server. so which of them is good?
Courier or Dovecot
Any live expirience for good values of this courier settings for cPanel server:
Maximum Imap Connections (Total)
Maximum Imap Connections Per Ip
Maximum TLS/SSL Imap Connections Per Ip
Maximum Pop3 Connections (Total)
Maximum Pop3 Connections Per Ip

I have a mail server which is courier, postfix, amavisd, using Mysql db and virtual mailboxes which I administer through postfixadmin.
I want to be able to add a set of default folders to all mailboxes created such as Possible Spam and some others.
I have investigated shared folders but this is not what i want, is there a way I can get courier/postfix to create a set of additional sub-folders when it creates a mailbox.
All mailboxes are accessed as IMAP mailboxes.
I have reported this to BurstNET admin/abuse/NOC and have added a line to block them for now.
Does this belong to anyone??? Nslookup/dig reveals nothing.
This is my /var/log/messages

my referals logs that I keep on a website, I have come accross the following this morning, Is this some one who is trying to gain access to the server etc.
[url]
[url]
[url]
[url]
[url]
I have the Ip addresses that they have come from and it resolves to a Russian (I Think) website.
Im just looking through all the folders on the server now and no data has been comprimised as far as I can see and im going to use the query strings in order to block access and also deny access via ip address.
I have started seeing the following error in the Event Viewer every day:
"An anonymous session connected from xxx.xxx.xxx.xxx has attempted to open an LSA policy handle on this machine. The attempt was rejected with STATUS_ACCESS_DENIED to prevent leaking security sensitive information to the anonymous caller. The application that made this attempt needs to be fixed. Please contact the application vendor. As a temporary workaround, this security measure can be disabled by setting the HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlLsaTurnOffAnonymousBlock DWORD value to 1. This message will be logged at most once a day."
The IP address is different every time. It is not an internal IP address or any I recognize. It is from the outside. I have read about this in the Microsoft site but it only mentioned how it might be an internal service/application attempting the access. This is not my case since I am seeing remote IP addresses. Anyone can help me dig deeper into this? How can I find out more about what's going on?
see the log entries below:

What can you say from the above log entries?
I'm using plesk with CentOS 6.6
After setting up some e-mail accounts over the plesk gui I tried to connect via a mail software (like thunderbird).
This failed with every combination of settings I tried. So I checked if the POP3/IMAP services are running correctly using telnet.
I connected using the following command:
Code:
telnet <host-ip> 110
The response was:
Code:
Trying <host-IP>...
Connected to <host-IP>.
Escape character is '^]'.
-ERR Cannot connect to POP server <host-IP> (<host-IP>:110), NB connect error 1460
Connection closed by foreign host.
Did I miss to enable a setting?
The Plesk gui schows me, that the corresponding services are running...
Yesterday we upgraded two of our servers to the latest Plesk 12.
The 1st server is an CentOS/CLoudlinux 6.x server and the 2nd an CentOS 5.x server.
Both of them were running Plesk 11.5 before the upgrade.
After the upgrade, we have the same issue in both servers which is that the START/TLS, SSL protocols at Courier imaps or pop3s do not work, and mail clients (outlook, thunderbird) return that the password is wrong when they connect over a secure connection.
In both of them, at the /var/log/maillog, we are getting the same messages, as the following one:
--------------------------------------------------------------------------
courier-imaps: couriertls: connect: error:1408A0C1:SSL routines:SSL3_GET_CLIENT_HELLO:no shared cipher
--------------------------------------------------------------------------
As the issue is in both server, we believe thath it there is a bug in the new version or the update script.
We have already checked all configurations which seem ok, tried to... reboot the machines, mailchk repair, but nothing seems to work.
