Configuring and managing the Pickup Directory-Part 2

In this article i suppose bring down how to configure pickup directory. Ok lets began.

By default pickup directory exits on every exchange 2007 computer that has installed Edge transport and hub transport installed. You cannot configure Pickup directory using Exchange management console and you have to use Exchange management shell.

Permissions you need to configure Pickup Directory

Configuring pickup Directory the account must have delegated the fallowing

  • Exchange Server Administrator role and local Administrators group for the target server 

Note: – if you performing this procedure in edge transport server role, account must have a member of Local administrators group.

Configuring Pickup directory location 

By default pickup directory located at C:\Program Files\Microsoft\Exchange Server\TransportRoles\Pickup. the Directory must be a local to the exchange 2007 computer.

Also pickup directory must have fallowing permissions.

· Administrator: Full Control

· System: Full Control

· Network Service: Read, Write, and Delete Subfolders and Files 

You can use below command to change location of pickup directory.

Set-TransportServer <Identity> -PickupDirectoryPath <LocalFilePath>

In my case I want to change my Pickup directory location to C:\Pickup from default location. So i run below command on EMS.

Set-TransportServer Exchange01 -PickupDirectoryPath "C:\Pickup”

image

  Now we can check location of pickup directory, Run fallowing command in EMS.

Get-TransportServer -Identity "E2k7-srv01" | Fl *PickupDirectoryPath*

image

Configuring maximum size for message headers that are accepted by pickup directory. 

By default maximum size of message header is 64 KB. Messages that contain headers that are larger than the specified maximum value are rejected by the Exchange 2007 server. Keep in mind when you add to value to maximum size use fallowing Units.

  • B (bytes)
  • KB (kilobytes)
  • MB (megabytes)
  • GB (gigabytes)

To configure maximum message header of pickup directory run fallowing command in EMS.

Set-TransportServer <Identity> -PickupDirectoryMaxHeaderSize <HeaderSize>

In here I configure it to 100 Kb. I run fallowing command in EMS.

Set-TransportServer E2k7-srv01 -PickupDirectoryMaxHeaderSize 100KB

image

Now we can check maximum size message of message header, Run fallowing command in EMS.

 Get-TransportServer -Identity "E2k7-srv01" | Fl *PickupDirectoryMaxHeaderSize*

image

 Configuring the Maximum Number of Recipients for Messages That Are Accepted by the Pickup Directory

By default, the maximum number of recipients in a message that can be processed by the Pickup directory is 100. Messages that contain more recipients than the specified maximum value are rejected by the Exchange 2007 server.

You can add values 1 to 10000 for Maximum Number of Recipients for Messages.

Run the following command to set maximum number of recipients for messages.

Set-TransportServer <Identity> -PickupDirectoryMaxRecipientsPerMessage <NumberOfRecipients>

For example configure it to 200 recipients for messages.

Set-TransportServer E2k7-srv01 -PickupDirectoryMaxRecipientsPerMessage 200

Now we can check Maximum Number of Recipients for Messages, Run fallowing command in EMS.

Get-TransportServer -Identity "E2k7-srv01" | Fl *PickupDirectoryMaxRecipientsPerMessage

image

Configuring the Maximum Rate of Message Processing for the Pickup Directory

By default, the Pickup directory can process messages at a rate of 100 messages per minute. Limiting the rate of message processing helps prevent performance issues that are caused by processing lots of messages in the Pickup directory.

Run fallowing command in EMS.

Set-TransportServer <Identity> -PickupDirectoryMaxMessagesPerMinute <MessagesPerMinute>

For example, to set the maximum rate of message processing by the Pickup directory to 200 messages per minute on an Exchange 2007 computer named E2k7-srv01, run the following command:

Set-TransportServer E2k7-srv01 -PickupDirectoryMaxMessagesPerMinute 200

image

  Now we can check Maximum Rate of Message, Run fallowing command in EMS.

 image

The valid input parameter is 1 to 20000 for PickupDirectoryMaxMessagesPerMinute.Pickup directory scan pickup directory once every 5 second or 12 times per minute for new messages. That interval you cannot configure.

The rate of message processing for both the Pickup directory and Replay directory is specified by the PickupDirectoryMaxMessagesPerMinute parameter.

Configuring and managing the Pickup Directory – Part 1

This article series contain two articles, in first article I provide Theoretical Basics information of pickup directory, how works and importance of pickup directory. In the second article I’ll describe how to configure pickup directory using Exchange management shell.

By default pickup directory exists in "\Transport Roles\Pickup" of installation directory on every Exchange 2007 computer that has installed Edge role or Hub role. If you formatted .eml file and placed in the pickup directory, pickup directory will submit to delivery. This method used by most Exchange Administrator for mail flow troubleshooting their emails by creating .eml files.

 

How Pickup Directory process messages 

Correctly formatted messages that copied to pickup directory is processed for submission for delivery as fallowing order.

  1. Pickup Directory checked for new email messaged every 5 seconds and you can’t change that time interval.By default pickup directory processed 100 messages and messaged are cannot open left in the directory for next pool.
  2. Limits that are messages in pickup directory checked.By default maximum header size is 64K and maximum recipient limit is 100 recipients.
  3. eml file rename to .tmp file.if .tmp file already exists it is renamed as a <file name><Date time>.tmp.If the file renaming fail, pickup process proceed for next eml file with generated event log.
  4. After the .tmp file converted to the email message, a “Delete on Close” command is issued and tmp file still exists but can’t open file by anyone else.
  5. after submitted the message to delivery ,a “Close” command issued,.tmp file is deleted from pickup directory.If deletion is failed, event error generated in event log.If transport services restated all .emp files are renamed to .eml files and start repressing messages.That could lead to duplicate mail messages transmission.

Requirements for Message Files in the Pickup Directory

 

A message file that is copied to pickup directory must be meet following conditions.

  • The message file must be a simple text file that contain with basic SMTP message format.
  • A message file extension must be a .eml.
  • At least one email address must be exists in from: or sender message header fields. If a single email address exists in the both from or sender filed,email address in the from: filed used as the originator of the message in the message envelop.
  • Only one email address can ever exist in the send filed.The sender filed is not required if email address present in From: filed.
  • Multiple e-mail addresses are allowed in the From: field, but a single e-mail address must also exist in the Sender field. The address in the Sender field is then used as the originator of the message in the message envelope.
  • At least one e-mail address must exist in the To:, Cc:, or Bcc: fields.
  • A blank line must exist between the message header and the message body.

 

Please see below example of text message that uses acceptable message formatting for the pickup directory.

To: chinthaka@msglab.info

From: Devid@msglab.info

Subject: Test message

This is test Message to check mail flow.

 

MIME contain messages are supported in pickup directory.Please see below example that is compatible with pickup directory

To: chinthaka@msglab.info
From: bob@nwtraders.com
Subject: Message subject
MIME-Version: 1.0
Content-Type: text/html; charset="iso-8859-1"
Content-Transfer-Encoding: 7bit
<HTML><BODY>
<TABLE>
<TR><TD>cell 1</TD><TD>cell 2</TD></TR>
<TR><TD>cell 3</TD><TD>cell 4</TD></TR>
</TABLE>
</BODY></HTML>
