If you take an email address like my iCloud account, it’s firstname.lastname@example.org. If I take the username and add a + at the end I can then type some characters and put it all in front of the @ and domain name then the mail will still come to me. So, let’s say I use it to create an AppleID for an APNS certificate. That would be: email@example.com Or iTunes: firstname.lastname@example.org Or iPhone1 (or these days iPad1): email@example.com The only gotcha is that occasionally you’ll run into some field on a webpage that has input validation for non alpha-numeric characters. Shouldn’t be the case, but it comes up from time to time. I use this a lot. For example, rather than use my email w/ my credit card company, I can use krypted+SOMECOMPANY@me.com and then I can create filters in Mail a little more easily for mail that comes from them. The best part about that is that it then shows me really easily who is selling my information that shouldn’t. For example, you’d think SOMECOMPANY gets enough $ out of me as a paying customer, but apparently not because they’ve sold my email address to at least 3 or 4 companies.
X traffic takes up a lot of network bandwidth and is insecure. SSH offers compression making it slightly more efficient and security…
The cron command has officially been deprecated in Mac OS X, but still functions if called upon. cron starts a process that executes commands at specified dates and times. Regularly scheduled commands can be specified according to instructions found in the crontab files in the directory /var/spool/cron/crontabs. Users can submit their own crontab files via the crontab command. Crontab copies the specified file or standard input if no file is specified, into a directory that holds all users’ crontabs. crontab options:
- The -e option edits a copy of the current users’ crontab file or creates an empty file to edit if crontab does not exist.
- The-r option removes a user’s crontab from the crontab directory.
- The -l options lists the crontab file for the invoking user.
- minute (0-59)
- hour (0-23)
- day of the month (1-31)
- month of the year (1-12)
- day of the week (0-6 with 0=Sunday)

When I say working directory I am referring to the current directory you are in when using a command prompt. Just an FYI. If you are ever unsure as to what your working directory is then you can use the pwd command to print it out to the screen.
SBC sends all their residential customers port 25 traffic to their mail server, regardless of the destination IP number, regardless if dial up, DSL, etc. Expect this trend to continue to other vendors with residential accounts to help combat spam. IMHO killing spam by effectively blocking out port 25 for end-users is not a huge deterrent of spam.
