Unhappy After yum upgrade, Postfix/Dovcott mail server is broken


Hello all,
I have just upgraded my server Centos 5 using yum and now my mail delievery is not working. Here are things that work:

It looks like I can send mail from squirrel mail but the mail never goes to internal/external users, gmail or my domain. Here is my postconf output.

I am unable to recieve mail from external mail servers.

Here is my setting for postfix:


Code:
[root@host postfix]# postconf -n
alias_database = hash:/etc/aliases
alias_maps = hash:/etc/aliases
broken_sasl_auth_clients = yes
command_directory = /usr/sbin
config_directory = /etc/postfix
daemon_directory = /usr/libexec/postfix
debug_peer_level = 2
disable_vrfy_command = yes
header_checks = regexp:/etc/postfix/header_checks
home_mailbox = Maildir/
html_directory = no
inet_interfaces = all
mail_owner = postfix
mailq_path = /usr/bin/mailq.postfix
manpage_directory = /usr/share/man
mydestination = $myhostname, localhost.$mydomain, localhost, $mydomain
mydomain = XXXXX.com
myhostname = host.XXXXX.com
mynetworks_style = host
myorigin = $mydomain
newaliases_path = /usr/bin/newaliases.postfix
queue_directory = /var/spool/postfix
readme_directory = /usr/share/doc/postfix-2.3.3/README_FILES
sample_directory = /usr/share/doc/postfix-2.3.3/samples
sendmail_path = /usr/sbin/sendmail.postfix
setgid_group = postdrop
smtpd_recipient_restrictions = permit_sasl_authenticated,       permit_mynetworks,      reject_unauth_destination,        reject_invalid_hostname,        reject_unknown_sender_domain,     reject_unknown_recipient_domain,        reject_rbl_client list.dsbl.org,        reject_rbl_client sbl-xbl.spamhaus.org,           reject_rbl_client cbl.abuseat.org,      reject_rbl_client dul.dnsbl.sorbs.net
smtpd_sasl_auth_enable = yes
smtpd_sasl_security_options = noanonymous
smtpd_tls_auth_only = yes
smtpd_tls_cert_file = /etc/postfix/cert.pem
smtpd_tls_key_file = /etc/postfix/key.pem
smtpd_use_tls = yes
tls_random_source = dev:/dev/urandom
unknown_local_recipient_reject_code = 550
What should I be looking for, in a bind here.

Thanks for the help,
Timgerr

When I run
Code:
 /usr/sbin/sendmail -v myaddress
it says that the mail was sent to root,
I do not see anything sent.

Here is the tail from /var/log/maillog
Code:

That looks like it is working.
I guess I have to clear my log,

OK, Here is more information, I cleaned it up for security reasons.
Code:

is this a SASL Authentication problem?

Thanks,'

Code:
Aug 24 00:28:09 host postfix/cleanup[6614]: 25F021C685A0: hold: header Received: from wf-out-1314.google.com

OK, I think it is my mail scanner
Code:
Starting MailScanner daemons:
         incoming postfix:                                 [  OK  ]
         outgoing postfix:                                 [  OK  ]
         MailScanner:        is only avaliable with the XS version at /usr/lib/perl5/vendor_perl/5.8.8/Compress/Zlib.pm line 9
BEGIN failed--compilation aborted at /usr/lib/perl5/vendor_perl/5.8.8/Compress/Zlib.pm line 9.
Compilation failed in require at /usr/lib/perl5/vendor_perl/5.8.8/Archive/Zip.pm line 11.
BEGIN failed--compilation aborted at /usr/lib/perl5/vendor_perl/5.8.8/Archive/Zip.pm line 11.

Compilation failed in require at /usr/sbin/MailScanner line 79.
BEGIN failed--compilation aborted at /usr/sbin/MailScanner line 79.
what do you think???

thanks for the reading,

Ok, you have a number of problems.
  1. Your SASL is incorrectly configured, and can't authenticate
  2. Mail is being held because there is a Received header_check rule that is holding the mail
  3. Mailscanner (amavisd-new + mods) is failing to load because there are version problems with your Compress::Zlib perl libraries.

There is too much to fix here all at once. You should focus on getting one portion of your mail server working at a time, in this order 1) plain SMTP, no authentication, no content filter, 2) authentication, 3) content_filter. 4) add various header_checks/body_checks/filter rules to tune.

Are you following some HowTo?

Honestly, I have no interest in reading or debugging somebody else's HowTo.

In my opinion, it is worthwhile learning about how the software you use works. Consider
The Book of Postfix to guide you to understanding what is going on.

Otherwise, you end up in a position where you can't resolve any problems that arise.

So, you have a couple of choices. You can either tear it all down, and try to follow the
HowTo again to rebuild it, checking each step along the way. You can fix one component at a time, but
still need to learn about how to do that. I can't advise which way is best for you.

You can comment out your header_checks in your main.cf for now.
You can comment out all the smtpd_sasl* and smtpd_tls* settings in main.cf until you get basic postfix working.

There is no content_filter setting shown in your output of postconf -n, so mailscanner is being configured in master.cf or elsewhere.
Show master.cf also.

Your mailscanner software required certain perl modules, which it seems you probably updated via CPAN or source (right?).
These are in conflict with your existing package-based or base perl modules. You need to update some dependent perl
modules such as List::Scalar. But ignore this for now, at least until you get your basic mail server running.

OK, thanks for the advice, I didnt mean to have you debug someone elses how to, I thought you wanted me to post what I was going/went from. I will try to disable all the security settings so I can get the smtp working.

I thank you for the time you have taken, this is a learning experience.

No problem, I didn't take it that way. I'm happy to help out.

It is very useful to read:

http://www.postfix.org/BASIC_CONFIGURATION_README.html
http://www.postfix.org/SOHO_README.html
http://www.postfix.org/STANDARD_CONF...ON_README.html

Then for content inspection:
http://www.postfix.org/CONTENT_INSPECTION_README.html

And for SASL/TLS:
http://www.postfix.org/SASL_README.html
http://www.postfix.org/TLS_README.html

It is a lot of documentation, and this is what makes trying to do too much at once so difficult to troubleshoot, which finally leads to:
http://www.postfix.org/DEBUG_README.html
