You will need to create a directory such as /var/mail/virtualmbox, assign the 
proper permissions then add that path to the above directive.

Configure Postfix for local delivery + forward to another address

[Keith Palmer]

I'd like to configure Postfix to locally deliver the mail and also forward
it to another address.

I'm using unix account for the mailboxes. How do I have to configure
/etc/aliases (or something else) to have it deliver the mail locally and
also forward a copy of that message on to another e-mail address (hosted
somewhere else)?

Thanks!

Need help to configure postfix to send only emails.

[Manoj Burande]

Hello There,

  Can anybody please provide me the required configuration for the
main.cf and master.cf to configure my postfix mail server to send
only emails.

1] Postfix will never accept any emails for any domains for the email
delivery except my locally hosted domain.
2] Only emails generated through my JAVA application will accept for the
delivery on the internet.
3] Postfix should also responsible to deliver locally generated emails(for
root e.g. syslogd..) to any other email user from other domain e.g.
manoj.bura...@artificialmachines.com.

I have already gone through the on line documentation for postfix but
found little bit information to configure postfix to send only emails.

Please help me.

Thanks in advance.

This is not correct. The OP's problem is that virtual_mailbox_base isn't
set. If the stored mailbox path is absolute rather than relative, simply
set virtual_mailbox_base to /. If the stored mailbox paths are relative,
put whatever directory they're relative to in virtual_mailbox_base.

If you need to define your LDAP servers in SRV records, you can
run a cron job that queries DNS, and rebuilds your "map.cf" files
based on an updated server list.

There is no support in Postfix for using SRV records to find LDAP servers.

What standard defines SRV records for LDAP?

A lot depends on the type of domain, for "virtual alias" domains for

other users in the domain.

Maybe the OP is referring to Microsoft Active Directory where some

mycingular.net verification failed: Name or service not known

[Dan Schaefer]

One of my coworkers would like to send emails from her blackberry using 
the work mail server and her work address. Whenever she attempts to send 
a message, I get the following error messages in the mail log:
Nov  4 13:28:35 pony postfix/smtpd[26853]: warning: 32.144.231.15:

Nov  4 13:28:38 pony postfix/smtpd[26853]: disconnect from

This apparently is a DNS problem:

Host mobile-032-144-231-015.mycingular.net not found: 3(NXDOMAIN)


I was wondering if errors like this could be ignored as long as her 
phone is setup to authenticate before sending messages?

Thanks in advance.

The "error" (actually "warning") is ignored, but logged, so that you
later understand why the client address is logged as unknown, and why any
restrictions that object to "unknown" clients may reject the transaction,
(if you use such restrictions).

Yes, it simply means that the internet provider which is used by the

Is support for:

_ldap._tcp.example.com

enough? Is this sufficiently well standardized?

What should the user interface be? Right now we have:

server_port = 389
server_host = hostname ...
server_host = ldap://hostname:389 ...
server_host = ldaps://hostname:389 ...

Unless there is an LDAP URI syntax that indirects through SRV records
implemented in the OpenLDAP library, Postfix would need a new syntax
to trigger the construction of a URI list from DNS.

I think it would be much simpler to write a cron job, than to ask Postfix
to determine the server list on the fly. Ugly issues creep in if DNS
queries time out, or temp-fail... This is much easier to handle in a
cron job that simply leaves previous settings untouched...

No changes required. This "warning" does not adversely impact the
delivery of email, unless you go out of your way (non-default setting)
to deny access to clients with unverifiable PTR records.

Neither the original recipient or the original sender received 
notification that there was a problem or any form of bounce message. The 
original recipient also never received the email.



Indeed. The original message was rejected with a permanent error
("550 5.7.1 Unable to relay"), as was the non-delivery notification.

  
My question is what happened to the email and the bounces and how can I 
change the setup so that if this occured in the future (i.e. the spam 
checking server can't communicate with the mailenable server) mail does 
not disappear.



Configure the Mailenable system such that it doesn't reject mail
with a PERMANENT error for conditions that you don't consider
permanent.

You can configure the Postfix SMTP client to pretend that permanent
errors aren't permanent, but that introduces other risks.

Wietse
  
I heard back from MailEnable and it occurs when MailEnable can't access 
the boxes. This is ok and probably as it should be.
When you say I can configure Postfix SMTP client to pretend that 
permanent errors aren't permanent is this something I could change 
temporarily (say for the time the MailEnable machine is rebooting) and 
then change back?

Postfix non-production snapshot 20091104

[Wietse Venema]

Postfix 2.7-20091104-nonprod introduces a "speed adjust" feature
that reduces the number of before-queue filter processes, without
reducing the number of before-filter SMTP server processes.

This addresses a concern of people in Europe who want to reject
all bad mail with a before-queue filter, instead of having to use
an after-queue filter and having to discard mail (which is illegal)
or having to bounce mail (which violates good network citizenship).

With "smtpd_proxy_options = speed_adjust", the SMTP server will
receive the entire message before it connects to a content filter.
For more information see the RELEASE_NOTES.

This is released as a non-production release first, because I took
the opportunity to clean up the existing before-queue filter code.

How to override an MX value for a particular domain only?

[Eric B.]

Hi,

I'm running postfix on an internal network with an internal DNS.  My 
internal DNS is configured for my particular domain (ie: mydomain.com).  I 
have an MX pointer that points to my postfix machine so any email being 
generated for mydomain.com from the internal network ends up at the postfix 
machine.  All that setup works fine.

My problem is the following.  The email received by Postfix for mydomain.com 
actually needs to be resent out into the internet destined for the actual 
mydomain.com email server located in a geographically different location. 
At the moment, Postfix will do an MX query for mydomain.com, realize that it 
is itself, and understandably not forward the email to the appropriate 
place.

How can I instruct Postfix on that server to ignore the MX record being 
served by the internal DNS and actually query an external DNS server for the 
MX pointer instead?  I looked through the main.cf config file, but can't 
seem to find anything.  Can I configure Postfix to use a different DNS 
server as opposed to the internal one specified by my resolve.conf file?

Any help or suggestions would be appreciated.

Thanks,

Eric

mycingular.net verification failed: Name or service not known

[Stan Hoeppner]

Dan Schaefer put forth on 11/4/2009 2:18 PM:

> The OP was all I had in the log for that transaction.

If that's truly the case then your Postfix is horribly broken.  Every
inbound message must/will either be rejected by smtpd, or accepted and
queued for delivery, or deferred by, qmgr.  There should always be a log
entry stating the disposition of each message.  Any logging at all is
useless without this.

Either it's in there and you can't locate it, or you've totally hosed
Postfix's logging somehow.  Stop grepping for the message ID and cat the
file, looking manually for all the entries around that transaction
timestamp.

Martijn's above suggestion will reliably send mail for mydomain.com to 
realmx.mydomain.com, which is what you may want to do.


Note: It does *not* query any DNS server for an MX record for 
mydomain.com, though. You would need to adapt it manually in case the 
external MX pointer is changed.



Hope this helps,

Don't slam the OP just yet...

It's very possible the mail client disconnected for some 
reason.  As one guess, maybe the client is configured to 
require TLS but the server doesn't offer it, so the client 
disconnects.  In that case, there wouldn't be a "reject: ..." 
message in the log.


Adding the client to debug_peer_list will probably give more 
information.


OP can grep the log for the smtpd process ID around the time 
in question to make sure nothing was missed.

for some reason, the client disconnected without attemtping to send mail.

No. the DNS issue is just a warning. if you look at your logs, you'll
probably find that you receive mail from clients with reverse dns issues.

By default, mail is accepted even if the client IP doesn't resolve.

time to reread the list welcome message, and provide infos about your
setup, ... etc.

note that your postfix and your client need to "agree" on tls &
authentication methods. if they disagree, your client will disconnect.

This is definitely helpful information; thanks.  I'll take a look into that 
ASAP.  My only concern with this setup, of course, is that it requires me to 
manually update the MX for the domain if ever it changes.

Is there no way to direct Postfix to a different DNS server (as opposed to 
the ones specified in resolve.conf) either for a particular domain, or for 
all domains altogether?

Thanks,

Eric

No, that's outside of the purview of Postfix. You could probably do

If you chroot-jail the smtp(8) delivery agent, it will use the resolv.conf
file in the chroot jail. This is ugly, you are probably solving the
wrong problem.

You could also use a cronjob to check for a change and then update
the configuration based on that change. Why can't you update resolve.conf?
