Inward Bound

The old Linux was setup as a gateway: one nic had the public ip that they would ssh to. I really do not like this configuration: I prefer hardware firewalls. As mentioned elsewhere, I also implement internal firewalls; that is, I have the hardware firewall forwarding the ports I want inward but at the Linux box I also specifically both disable and block all ports not being used.

Take Control of Apple Mail, Second Edition

Simple outgoing email for SCO Unix (and Linux)   2013/05/22 rblake
- Configuring MMDF or Sendmail on SCO Unix was never fun and it only gets worse as fewer people care about any of it. Here is a simple fix for scripted outgoing email -

Email addresses still matter (for now)  
- Email: it has helped kill the post office, is the primary source of spam, is critical to many businesses and, after malware, is probably the single largest source of user difficulties. Every internet user has at least one email address and many of us have several. Email is ubiquitous and very important. It's also threatened: many people use services like Facebook and Google+ for most of their daily communication. Somewhat ironically, you typically need an email address to sign up for these services, but the deficiencies of email have even caused some to try to eschew it completely and only use alternatives like those. That trend may continue; in a decade or so, "email" may be as antiquated as "gopher" and "uucp" are today. -

Why you shouldn't send Word attachments   2011/08/31 BigDumbDinosaur
- As I continued my walk, I thought about how email issues are likely the most common mysteries my neighbors have with their computers. Notice that I said "mysteries" and not "problems". That's because most email issues are from misunderstanding and confusion, not necessarily any real problem. A virus infection is a problem. A dead hard drive is also a problem, but email is usually simple confusion or lack of knowledge. -

Helping my sister-in-law with Gmail   2011/06/02 TonyLawrence

Gmail vs. in-house Mail Server   2011/07/06 TonyLawrence
- Well, in fact I can recommend this for some cases. It may not be for everyone - there are some disadvantages - but it can make a lot of sense and the price is reasonable, especially for very small organizations. -

Who is Louella Slaton?  
- Why do I keep getting Louella Slaton's email: For some time now, I have been getting email directed to Louella Slaton. That's obviously a mistake both on grounds of gender and appellation, and therefor has been a cause of curiosity for me. Although I do sometimes use made up names for illustrative purposes in articles and other postings, the name "Louella Slaton" has never appeared in any post or correspondence of mine until today. -

Apache Spammers

Charging for email  
- Yahoo and AOL have the courage to start charging for mail: Yahoo and AOL plan to introduce a paid service that lets mass mailers skip their spam filters and go right to the users mailbox. While a lot of people are up in arms about this, I think we all know that something has to be done about junk mail. I think there are adjustments that will need to be made (AOL has already said that they'll waive the fee for non-profits, for example) and the pricing might need some creativity (a flat rate option could be helpful), but I think the basic concept is good. -

Why you need a true secondary DNS server   2010/01/04 anonymous
- Some people may wonder why secondary MX records, or DNS servers are necessary, and until you have had an equipment failure, or outage, you might still be wondering. Most shared hosting out there will give you DNS servers (primary and secondary) since your registrar requires this. -

All I want for Xmas is for Google to..Gmail   2011/09/17 TonyLawrence
- Things I wish Google would do in Gmail: Google has become a big part of my daily life: Gmail, Google search, Google News, Google Adsense and Google Adwords are daily usage for me. Other tools like Google Earth don't get used daily, but are certainly part of the empire Google is building on my desktop. -
