Maximum attachment size formula
The maximum attachment size formulas use the following variables:
„
Encoding adjustment The factor by which the attachment size increases
when the attachment is encoded and attached to an e-mail message.
„
Memory adjustment The factor by which the encoded size increases when
an e-mail message is loaded into the internal representation of the e-mail
message in memory.
„
Buffer memory The memory required by the parts of the application not
involved in processing inbound e-mail messages, which is fairly static.
The approximate values for these variables, used when calculating how much
memory to reserve to process an e-mail message, are:
„
Encoding adjustment : 1.3 (this can vary slightly based on the encoding
used)
„
Memory adjustment : 1.2 (this factor decreases slightly, the larger the
e-mail is, but it has been left as a fixed value)
„
Buffer memory : 20 MB
Note: When the following subsections specify an attachment size, they mean the
total size of all attachments of an e-mail message. Also, the size of the body of
an e-mail lowers the supported attachment size by the size of the content of the
message. However, in most cases, the content of an e-mail is negligible
compared to large attachments.
