I am new to postfix , I have compiled postfix from scratch to include the pgsql, and tls driver, and I have installed the dovecot and squirrel packages and configured them as far as possible on Centos 6.3 based server, my traget is to be to send and receive emails from my domain using squirell we interface, but I am getting the following:
On regular basis as long as I am logged in the squirell mail I keep having:

    Dec 15 19:23:36 myserver dovecot: auth: pgsql: Connected to postfix
    Dec 15 19:23:36 myserver dovecot: imap-login: Login: user=<me@mydomain.nl>,method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, mpid=30914, TLS
    Dec 15 19:23:36 myserver dovecot: imap(me@mydomain.nl): Connection closed bytes=46/364

And when trying to send a message I am getting:

    warning: request to update table btree:/var/spool/postfix/smtpd_tls_session_cache in non-postfi directory /var/spool/postfix
    Dec 15 18:33:37 myserver postfix/tlsmgr[30573]: warning: redirecting the request to postfix-owned data_directory /var/lib/postfix
    Dec 15 18:33:37 myserver postfix/smtpd[30571]: connect from localhost.localdomain[127.0.0.1]
    Dec 15 18:33:37 myserver postfix/smtpd[30571]: lost connection after UNKNOWN from localhost.localdomain[127.0.0.1]
    Dec 15 18:33:37 myserver postfix/smtpd[30571]: disconnect from localhost.localdomain[127.0.0.1]

So I can see that I have the following problems (Until now :-) ):<br>
     1- Not able to send an email for this UNKOWN issue.<br>
     2- Send password in plain and encrypted over TLS.<br>
     3-  Issue in updating the table btree.<br>
     4- Issue in redirecting the request to postfx-owned data directory<br>
I am not sure if they are all related, and if it is ok to post them in one post.<br>
My configurations are:<br>

i have not digged into other problems, but the warnings concerning file ownerships should be corrected by running "postfix set-permissions" as root

the UNKNOWN issue does not mean much. usually postfix would state after MAIL FROM or after RCPT TO or the likes so you can determine at what step of the smtp transactions things went wrong. in your case, nothing was transmitted so the last command is UNKNOWN

can you send mail without ssl/tls. did you compile with tls or ssl ? is your client using ssl or tls ? mixing both usually ends up not working properly

Yes I comipled Postfix with ssl and tls, if you want please send me the command you want to check the tls.
I configured the squirrelmail to use TLS in config.pl
By the way I am using a self signed certificate for the email which is different than the certificate of the site which a verified one.
Any advie regarding this issue?
I will try the command postfix set-permissions an try again.

as far as i know, you can't : it is either one or the other. interoperability between them is still quite messy

I configured the squirrelmail to use TLS in config.pl

try squirrelmail without tls so we can confirm this is an ssl/tls issue and the rest of the setup works fine. as a side note, if both run on the same machine using ssl/tls is quite useless. you'd have similar security with regular tcp, and much better security using a unix socket with proper permissions

By the way I am using a self signed certificate for the email which is different than the certificate of the site which a verified one.
Any advie regarding this issue?

yes : do not do this. if you do, you'll most likely need to setup an option in squirrelmail to instruct it to ignore certificate verification checks. this might be the source of your problem.

Ok, I have configured the postfix and dovecot to use TLS, if I configured the squirrelmail to use open ports would that work?

TLS vs ssl is not a config option. it is a compile time option. you can compile it either against libssl or against libtls, both being mutually exclusive (that is as far as i know). on linux, you're most likely using tls. whatever the problem the squirrelmail log should provide the information you cannot find in postfix's log. if you don't need ssl, don't bother.

given the logs, i can tell that the tls negociation fails. i can't guarantee that nothing else will fail along the line if you solve the problem or skip ssl altogether. if your postfix config is correct, it will work. you need to try.

if your postfix setup is correct, you should be able to use port 25.
if you want to use a unix socket, you can clone the line containing port 25 and replace "25" with the path to the desired socket and "inet" with "unix" in your master.cf

Can you please tell me the location of the squirrlmail log? it is installed in /usr/lib/share/squirrelmail

no idea. this depends on your setup, and i do not know much about squirrelmail

assuming you installed it on apache with mod_php,
it is likely that errors are actually php errors that default to be sent to stderr and hence end up in apache's error-log

- squirrelmail may log it's own errors but that is unlikely
- it may raise php errors
- if so, your php.ini determines where these errors go (usually stdout)
- if they are logged to sdtout, apache usually sends them to it's error-log
- they can be just trashed by either of the above

if you can't find it, you can grep for words such as "cyrrus" or "smtp" or your user name recursively in /var/log

I ran postfix set-permissionsbut I still get the error in create (Image attached, it seems it does not like the file name .sent
However the dovecot created its mailbox in /home/vmail/usernma/.xxxxxx

You were indeed correct the tls port is the port created the problem, however when I removed it I got the following:Dec 18 22:21:23 myserver postfix/lmtp[849]: 78106DEBAA: to=<myemail@yahoo.com>, relay=127.0.0.1[127.0.0.1]:10024, delay=2, delays=0.16/0.06/0.05/1.8, dsn=2.0.0, status=sent (250 2.0.0 from MTA(smtp:[127.0.0.1]:10025): 250 2.0.0 Ok: queued as 4B08CDEBB0)

One more point I have check for the user admin@mydomain.com and I got this output:

#postmap -q admin@mydomian.com pgsql:/etc/postfix/pgsql_virtual_mailbox_maps.cf
admin@mydomian.com/


So I can see the user is there.

I ran postfix set-permissionsbut I still get the error in create (Image attached, it seems it does not like the file name .sent

you can set the file names used for the sent mail in squirrelmail's config. apparently you are not allowed to use filenames that start with a dot. i see no reasonable reason why you would want to do so anyway. i'm not even sure the imap specifications allow this.

And I can see libssl there so I assume that my installation support ssl, correct?

yes. your problem is probably the self-signed certificate. there should be a way to instruct squirrelmail to ignore the cert validation. this feature is builtin the cyrus imap php extension which i assume squirrelmail uses.

the apache/squirrelmail log should display an explicit error

everything seems ok, (including MXs and mail for your domain is allowed) except that the user does not exist

i'd need to see how you refer to the virtual users map in postfix's config

i saw this warning i had missed previously by accident

Dec 18 22:23:40 myserver postfix/trivial-rewrite[828]: warning: do not list domain mydomain.com in BOTH mydestination and virtual_mailbox_domains

most likely, postfix checks for mydestination first and assumes the user is a local user of the machine. in this case, it will use aliases.map and not your postgres database to lookup the user.

this can be checked by raising the log level using debug_peer...something in your main.cf. postfix should log each map query with the name of the table, the query and the answer

but I have removed the name already from the main.cf and I do not have this warning any more in the log file, honestly I feel the problem is in dovecot-sql.conf, because even the commands:
       doveadm quota get -a user
       doveadm quota get -a user@mydomain.com
    Are not working as well, the problem I can not find much explanation for this config with postgres and my database structure, what do you think about this file?

virtual_mailbox_maps is used by the virtual delivery manager if the domain is listed in virtual_domains

given the fact that your last log shows  this line

Dec 18 23:13:27 myserver postfix/local[1329]: 42F0CDEBC1: to=<admin@mydomain.com>, relay=local, delay=0.11, delays=0.01/0.05/0/0.05, dsn=5.1.1, status=bounced (unknown user: "admin")

postfix is using the local delivery manager instead of vitual so you probably removed the long line (or should post a more recent log)

if the dovecot commands are not working, most likely there is also a problem in dovecot

also remind that increased logging gives more information
