Most mail delivery systems have a maximum size for attachments. In the past, if an elog attachment was larger than this size, the email server refused to accept this email and no notification is sent. Now one can specify the maximum allowed email attachment size with

Max email attachment size = <n>

where <n> is the number of bytes. If an email attachment is larger than <n>, the attachment is not sent with the email notification, but rather replaced by a link to the elog server for that attachment. By clicking on the link in the email notification, a browser will then open and download the large attachment. For each each elog installation, the admin has to figure out what the maximum attachment size of their SMTP server is, and then put this number into the elogd.cfg setting  above. For most installations, the default of 10 MB will just work fine.
