How can I save storage space? Can I allow messages to expire?

The archive of your domain contains all messages that were considered legitimate by the filter. If your memory is not enough, then you have the option to let older messages expire.

Go to "Archiving" > "Settings" and check the option "Messages expire" and enter a number of days that a message should remain stored. Older messages that are no longer needed can be automatically removed from the archive if the storage space is insufficient.

To save storage space, you have the possibility to specify which parts of a message EuropeanMX should archive. EuropeanMX offers the following options for this:

• Message Header

  ---

  Searches for text in the header name or in the value of the message. For example, if you are looking for messages that have an X-Campaign header or have a specific name in the CC header. This setting only has a small impact on memory consumption.
  
• HTML

  ---

  Searches the HTML version of the message. Many senders send their messages both in HTML and as a text-only version. We recommend leaving this option active so that messages that do not contain pure text messages can also be searched. This setting only has a small impact on memory consumption.
  
• Text

  ---

  Searches the plain text version of the message (purely text-based). As some senders send the message without HTML or the text cannot be extracted from the HTML version, you should always leave this option active. This setting only has a small impact on memory consumption.
  
• Images (using OCR)

  ---

  Searches the image for contained text. Images received by email are searched by EuropeanMX for contained text using OCR and the found text is added to the index. This setting has a large impact on memory consumption.
  
• Attachments / Documents (.doc)

  ---

  Searches a Word document (Microsoft Word 2003 and earlier) for text and adds it to the index. This setting has a large impact on memory consumption.
  
• Attachments / Documents (.docx)

  ---

  Searches a Word document (Microsoft Word 2007 and earlier) for text and adds it to the index. This setting has a medium impact on memory consumption.
  
• Attachments / Documents (.pdf)

  ---

  Searches an unencrypted pdf document for text, which is added to the index along with some metadata (e.g. author and subject). However, images are not processed with OCR. This setting has a medium impact on memory consumption.
  

If the memory is still not sufficient, you can of course extend it. Please contact our support for this.
