The last packet successfully received from the server was 60.410.682 milliseconds ago. The last packet sent successfully to the server was 60.410.687 milliseconds ago. is longer than the server configured value of 'wait_timeout'. You should consider either expiring and/or testing connection validity before use in your application, increasing the server configured values for client timeouts, or using the Connector/J connection property 'auto Reconnect= true' to avoid this problem.

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?

Why are there many people setting their TTL to higher values rather than lower ones? By setting it lower, won't it propagate faster?

Same as when we write a phpinfo file (that shows libraries, etc) to know php values..

If you enable ssl in apache, you can verify a client certificate. If so apache will create a environment variable for you with the name 'SSL_CLIENT_VERIFY' with values 'NONE, SUCCESS, GENEROUS or FAILED:reason'. URL....What is the meaning of this different values?

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'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.

I am trying to secure my VPS and one thing noted in a recent scan was SSL v2 and v3 being supported for SMTP, POP3 and IMAP. So a check of ‘Disabling SSLv3 Support on Servers’ and the Postfix configuration settings suggest:
smtpd_tls_mandatory_exclude_ciphers = aNULL, MD5
# Preferred syntax with Postfix = 2.5:
smtpd_tls_mandatory_protocols = !SSLv2, !SSLv3
This actually goes further than disabling SSLv2 and v3 and also excludes the use of NULL and MD5 ciphers.
The Postfix conf file, main.cf exists in two places on my VPS:
# find / -name main.cf
/usr/libexec/postfix/main.cf
/etc/postfix/main.cf
Examining both only the copy in /etc/postfix/ is configured and at the end of this file I can find all the Plesk settings, including some RBLs I’ve defined via the UI. Hence I know this is the working config as of the two, it’s the only one actually configured. Hence I add the required commands to the config:
...
smtpd_tls_key_file = $smtpd_tls_cert_file
smtpd_tls_security_level = may
smtpd_use_tls = yes
smtp_tls_security_level = may
[Code] ....
I then go to the Plesk Tools & Settings > Services Management and restart:
SMTP Server (Postfix)
And for good measure:
Plesk milter (Postfix)
I then test whether SSLv2 is enabled:
# openssl s_client -connect x.x.x.x:25 -starttls smtp -ssl2
Now what I should get back is an error as the attempt to connect with SSLv2 should fail as it's an excluded protocol, but instead what I get back is the Plesk cert and a connection:
# openssl s_client -connect x.x.x.x:25 -starttls smtp -ssl2
CONNECTED(00000003)
depth=0 C = US, ST = Virginia, L = Herndon, O = Parallels, OU = Parallels Panel, CN = Parallels Panel, emailAddress = info@parallels.com
verify error:num=18:self signed certificate
...
Why? What do I need to do to have Postfix use the updated config and refuse an SSL2 connection?
I seem to have the same issue with Courier having made similar changes to the /etc/courier-imap/pop3d-ssl file:
# Iain 2014-12-12
# TLS_CIPHER_LIST="SSLv3:TLSv1:HIGH:!LOW:!MEDIUM:!EXP:!NULL:!aNULL@STRENGTH"
TLS_CIPHER_LIST="TLSv1:HIGH:MEDIUM:!LOW:!EXP:!NULL:!aNULL@STRENGTH"
And /etc/courier-imap/imapd-ssl file:
# Iain 2014-12-12
# TLS_PROTOCOL=SSL23
TLS_PROTOCOL=TLS1
actually, this should probably read:
# Iain 2014-12-12
# TLS_PROTOCOL=SSL23
TLS_PROTOCOL=TLS1, TLS1.1, TLD1.2
Why am I unable to disable SSL v2 and v3 for SMTP/POP3/IMAP with Postfix and Courier?

is there a way to set global php values settings for all Domains in Plesk 12. In the older version of Plesk I can do it by linux in /etc/php.ini and restart the apache and all Domains will be load this configuration. But from Plesk 11 the settings are not loading from /etc/php.ini, only by the own php.ini file.How can I do it for all domains?

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.
