Laptop SMTP server vs UUCP over TCP

either/or with

I am looking into the cutting the web mail services out of the picture 
and using
my laptop to directly receive and send emails.

Has anybody done this?

=============================================================== From: Benjamin Stewart ------------------------------------------------------ It's a great idea, but I think you're in for several challenges there. I'm sure folks more knowledgeable than I will weigh in, but here's my lay understanding: - For the receiving end, your SMTP server has to ALWAYS be on and connected. Otherwise messages will bounce. That's probably going to be a problem with your laptop! - For the sending end, you may find that many/most public servers are going to refuse to relay mail from a dynamic IP address assigned to (e.g. ComCast) customer networks. There's probably a lot more spam than ham coming from those dynamic addresses. If you can overcome those challenges, have at it, and tell us what you did!

=============================================================== From: John Aldrich ------------------------------------------------------ Quoting Benjamin Stewart : Some good points. One possible way around the dynamic IP problem is to pay for a static. Some companies will sell you a single static for a small up-charge, some will only sell you a block and want to charge you $100/month just for the privilege of having a static IP, on top of your normal internet bill. Another complication is, some internet providers will not allow you to run a server on their network unless you pay for a business account and will ask you why you want a static IP and then tell you you have to pay for a business account.

=============================================================== From: Andrew Rodgers ------------------------------------------------------ Much cheaper and easier to create a virtual server for this, and connect to it using IMAP or SMTP relaying. Check out digital ocean or linode.

=============================================================== From: Justin W Elam ------------------------------------------------------ Have a hosting provider host your domain and email from services like 1and1 Rackspace Google Apps Microsoft Live Fastmail Zoho and so on Your mileage may vary, good luck -- ------------------------------------- Justin W Elam E-mail ::: - ###

And as soon as you head towards a UUCP gateway you may as well be paying someone for a host and using POP or IMAP to retrieve your mail. There are distributed messaging systems out there, RetroShare uses the Bittorrent hash table to resolve keys to IP addresses, and this can happen fairly quickly after you plug a computer in a new place, but I haven't got the store-and-forward bits working yet in a useful way.

=============================================================== From: Dave Brockman ------------------------------------------------------ -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I have used UUCP over TCP. I hope I never have to see UUCP in any flavor ever again. I don't think you will have anything to gain, and you still have to have something with an MX to actually receive the email, and then UUCP it to you, or wait for you to UUCP it from them. SMTP requires a static IP address, an MX record in DNS, a matching reverse PTR in RDNS, so you really need 3 static and stable IP addresses to receive email. Two DNS servers and your MX itself. Having an MX record < 60 minutes will get you flagged as a spammer and rejected at connection anywhere you really want to send email. If your laptop is not connected 24/7 with a static IP address, I don't see how you would actually receive email on it.... I encourage you and everyone on this list to self-host your own email. I know at least one Datacenter in town that doesn't have any extra black boxes or fiber taps....

=============================================================== From: Darren Breidigan ------------------------------------------------------ Playing with sendmail gave me the idea but, I realized that I've been sending to a static address. (Puts head down and continues to work on important project)

=============================================================== From: Darren Breidigan ------------------------------------------------------ That was the next question. The assumption is that you need a domain for this (HostGator/GoDaddy) and point it to your server. The idea behind the UUCP was to send PC to PC email without a web provider and maybe tucked into a VPN/SSL setup or even a VIDALIA router.

=============================================================== From: Mike Harrison ------------------------------------------------------ Darren: Back in the days when were were doing lots of UUCP (pre-1995/1996), it was for mail servers that were not always online. Bandwidth and connection time was expensive and limited. There were a handful of places in Chattanooga that did UUCP, some using bespoke one of a kind UUCP to pre internet email gateways. For example, I built one for Chamblis Bahner for UUCP to cc:Mail. I seem to remember building one for some Word Perfect email product. The "Chattanooga Online" original TBBS BBS to the "Internet" email gateway was UUCP to a company called "Holonet", and we were using a satellite downlink for newsgroups. UUCP was seldom done over a VPN or a "Vidalia/onion/tor.." router, I never saw it done. In a lot of ways it was like FidoNet (or FidoNet was a UUCP variant, either way) and we were just so happy at the time that it worked.. Still, it was a good solution then, and if done well could be a good solution now in specific circumstances. Traditional UUCP email addresses (Bang Paths) are a pain to translate back and forth to. Using SMTP is a LOT easier, and can also be used on a "store and forward" configuration, although finding a provider that will do it well is a good trick. The USA and "1st world" has standardized on "always on" connections to mail servers. These features are disabled (but can be turned back on) in modern versions of Sendmail and many others don't support them at all. The TURN, ETRN and other commands are seldom used, as are configurations that tell an SMTP server to accept and queue mail for another domain. Thanks to spam, we have become much less willing get in the middle and mail servers are more "direct".

=============================================================== From: Know Juan ------------------------------------------------------ Hosting your own mail server is a pain in the neck, good luck! Along these lines, this might be of interest:
