Configuring System E-Mail Settings

Encoding Method for Attachments According to File Type

Enter the transfer encoding for attachments by file type.

When an attachment is added to an e-mail, the default encoding type is used unless you specify the attachment file type to be encoded with some other method. The setting consists of file type and encoding method pairs. The values are separated with an equal sign (=) and the pairs are separated with a semicolon (;). An asterisk (*) is a wild card character that can be used to change the default encoding.

For example, value wav=base64;txt=7bit;*=8bit; defines that wav files are encoded with the base64 encoding, text files with 7bit and all other files with 8bit. The default value is base64.

Character Set for E-Mail Message Body

Enter the character set for e-mail body. The selectable values are defined by the MIME standard. The default value is utf-8.

Encoding Method for Sent E-Mails

Enter the transfer encoding method for sent e-mails. The selectable values are defined by the MIME standard. The default value is 8 bit.

Max. Size of Incoming E-Mail (KB)

Enter the maximum mail size that is read via the IMAP connection for incoming mails. In practice the accepted mail size may be smaller than this since binary attachments are encoded. If a mail is too large, the body text and attachments are not read from the mail server.

The maximum value is 100 000 KB and the default value is 25000 KB.

The maximum size of the sent e-mail is 100 MB, and the maximum size of one attachment is 10 MB, these values cannot be adjusted.

Save E-Mail Attachments in Folder

Select this option if you want to save e-mail attachments into a disk instead of the database.

Enter the location in the Attachment Folder field. Otherwise the attachments are saved into the database.

Attachment Folder

Enter the file location using the UNC name format or browse to the correct folder.

The structure of the created subfolders in the location is YYYY\MM\DD.

Minimum File Size (Bytes)

Enter the minimum size of the created file. The default value is 8000.

If the attachment size is less than 8000, the attachment is saved into the database.

Save Email in MIME Format

When this option is selected, emails through the OII integration are saved in the MIME format. By default, this setting is enabled.

Added in 2005.

E-Mail Too Large

Enter the replacement text if the received mail is too large. The maximum size is the value defined in Max. E-Mail Size (KB). The default value is *** ERROR: Mail was too big, body and attachments dropped ***.

E-Mail with No Body Text

Enter the replacement text if the received mail has no body text at all, or if an unusual error occurs when receiving the body text part. The default value is ***WARNING: Could not get IMAP body text.

As of 1608, it is possible to connect with an external SMTP server managing the outgoing mail.
