Using the Announcer feature, how many email addresses can you send email to? January 30, 2008
Posted by Guy Cook in : Features , add a commentHow many email addresses can you send email to?
When sending mail, there is a limit to how many recipients you can send an email to at one time. This limit is 4,096 bytes, or four kilobytes. Please note that this is not a limit on the size of the actual email itself; this is a limit on the size of the portion of the email which holds the recipient’s email addresses (e.g. the “To”, “CC” and “BCC” fields).
Here’s how it works: each character in an email address, excluding commas, semicolons and spaces (which are used to separate multiple email addresses in the same field, depending on the email client you are using), uses up one byte. Therefore, if your email addresses are twenty-two characters long on average, then one email can be sent to as many as 186 recipients.
In the event that the email addresses exceed the four kilobyte limit, that portion of the email is truncated (shortened), so that it will no longer be over the limit. This means that some of the people on the recipient list will not get the email you sent.
As a general rule-of-thumb, you will be more than reasonably safe if you never send an individual email to more than 100 recipients at any one time.

Canonical issues: www vs. non-www January 4, 2008

Canonical issues: www vs. non-www There’s been much talk lately of canonical issues and search engines. This is where both the www and non-www versions of your pages are listed in a search engine. This is said to possibly trigger a duplicate content penalty and/or split page rank. If this is of concern to you, you may wish to use the following, but be aware that you may suffer a further loss of traffic while the engines sort out what’s what. This example is where you wish to direct all non-www traffic to www. Add the following to your .htaccess file.
Options +FollowSymLinks
RewriteEngine on
RewriteCond %{HTTP_HOST} ^yoursite.com [NC]
RewriteRule ^(.*)$ http://www.yoursite.com/$1 [L,R=301]
Ensure that all your links to folders always end in a trailing / if there is no filename after that link.
FrontPage users: in addition to the above, you’ll also need to change the .htaccess files in: _vti_bin
_vti_bin /_vti_adm
_vti_bin/ _vti_aut Replace “Options None” to “Options +FollowSymLinks” Those folders are part of your FrontPage extensions on the server, so you’ll need to gain access via FTP. Note: test, test and test again after making changes. Test *immediately* after implementing 301 redirects. If you find anything wrong, remove the redirect immediately. User a server header checker to ensure that you’re getting a correct 301 response when using the old URL.
