The requirement was “basic” SMTP AUTH… so PLAIN/LOGIN functionality, no need for TLS, and use the existing user accounts on the linux machine. Local email needs to still function (mail from cmd line) but anything from a “remote” user would require a username/password to be verified before allowing the machine to send the email.

Notes:
======
1) need to allow sendmail to talk to more than just localhost (allow network connections)
- firewall (open ports, or disable for testing)
- “dnl DAEMON_OPTIONS(`Port=smtp,Addr=127.0.0.1, Name=MTA’)” line in the sendmail.mc instead of “DAEMON_OPTIONS(`Port=smtp,Addr=127.0.0.1, Name=MTA’)” …. adding the dnl in front of the command basically comments it out.

2) need to install from source (for our RedHat 7.3 machine, I used these versions):
- cyrus-sasl (v1.5.24)
- sendmail (8.11.6)
* these versions were selected because they matched the rpms/version that were already installed on machine. I needed to be rebuild to provide support for PLAIN and LOGIN AUTH methods… which I understand are not typically available via RPMs.

3) Important lines in the sendmail.mc:
————————————————————————————————
define(`confAUTH_OPTIONS’, `A’)dnl
TRUST_AUTH_MECH(`LOGIN PLAIN’)dnl
define(`confAUTH_MECHANISMS’, `LOGIN PLAIN’)dnl
————————————————————————————————
make sure that none of these have a dnl in front of them… that would cause them to be ignored (considered comments).

4) There needs to be a file: /usr/lib/sasl/Sendmail.conf (note the upper-case S in filename) with the following line (only line):
- “pwcheck_method: PAM”

5) Not sure if this is actually required, but during my travels, I found that I need the file /etc/sasldb to exist and it can only be read/writeable by root so:
- touch /etc/sasldb (to create it if necessary)
- chown root:root /etc/sasldb (to change it to owner/group root)
- chmod 600 /etc/sasldb (to ensure that only root user can read/write file)

6) I did confirm that these changes will only require AUTH on connections from external mail clients (doesn’t affect mail cmd-line on the host).

7) If you want to test via “telnet host 25″ the sequence of events would be:
-> EHLO hostname (doesn’t matter what you use as hostname)
-> AUTH LOGIN
<- 334 VXNlcm5hbWU6
-> anNueWRlcg== (Base64 encoded username, ie: jsnyder thru the base64 encoder)
<- 334 UGFzc3dvcmQ6
-> dGVzdGluZw== (Base64 encoded password for username above)
<- 235 2.0.0 OK Authenticated (this is a good sign... no need to continue)
-> QUIT

Useful commands:
==============
- m4 /etc/mail/sendmail.mc > /etc/sendmail.cf (converts the sendmail.mc file into the necessary sendmail.cf for sendmail to use)

- sendmail -d0.1 -bv root (shows if SASL support is available in sendmail in the list of “Compiled with:” items)

- sendmail -d0.20 -bv (shows location it is expecting sendmail.cf … “Def Conf file:” line).

- sendmail -O LogLevel=33 -bs (runs a quick instance of sendmail with logging turned up to level 33, and then you can enter “ehlo localhost” and it should give you back the options for the server… should include the line: “250-AUTH LOGIN PLAIN” when everything is configured correctly).

Based on these numbers, here are some basic averages (based on 58 days):
phone conversation a day: 6.1 up slightly from the first 4-week average of 5.2 mins
data sent per day: 0.134 up slightly from 0.114 MB
data received per day: 2.120MB up modestly from 1.828 MB

Couple of observations… I have “settled” into a routine with the device. I purchased the Griffin Technologies iTrip AutoPilot and have been listening to podcasts (tWiT, BOL, the404, StackOverflow, gdgt weekly, OpenWebPodcast) during commute. This unit (model 4046-TRPAUTOC) supports charging the phone + FM transmitter, with the extra benefit of Prev/Next/Play&Pause all on the lighter-plug (very useful!).

Apps installed:

• Pandora Radio
• ShifD
• AIM (just in case)
• Twittelator
• BreakLite
• LumenLite
• Apple iTunes Remote

I have found, that I am using it primarily for reading email and rss feeds (google-reader), and was keeping up with the Olympics news on it as well. I also use the music a fair amount, and I am hoping to find a couple of good podcasts that I can listen to on the commute time (to learn something while I drive :-).

I am documenting it here, incase someone else wants to do the same thing.

Basically, you need to edit the prefs.js file for Netscape (C:\Documents and Settings\*username*\Application Data\Mozilla\Profiles\default\*.slt\prefs.js)

Adding the following lines:

user_pref("network.protocol-handler.app.http", "iexplore.exe");
user_pref("network.protocol-handler.app.https", "iexplore.exe");
user_pref("network.protocol-handler.expose.http", false);
user_pref("network.protocol-handler.expose.https", false);


Also, important to note that you need to have Netscape closed when editing this file… otherwise the changes will not take effect. Easiest way to ensure this, make sure that netscp.exe isn’t running in Task manager.

The phone arrived to the ATT store on July 25th, but I was on a plane to Texas when it was delivered. So I had to wait until Tuesday the 29th in the evening to pick it up. First impressions (like so many others)…. WOW, Apple does a great job with first impressions of the device (from opening the box to the installed apps/etc, web access, emails, etc).

I have been using the iPhone 3G now for about two weeks, and it (and it’s data plan) have changed the way I use my cell phone. I definitely appreciate having internet and gps just about anywhere… especially when I have that 15-30mins of downtime while the boys are at an activity or wrapping up something. I enjoy being able to tweet, read blogs with Google Reader, and get a quick update of my emails while out and about. I imagine (tho haven’t needed yet) the GPS could be handy especially with google maps to find where I am in a different city (and locations for food/products).

List of apps that I have installed so far:

• Pandora (streaming music)
• SHIFD (shifting notes/links/locations between devices)
• AIM (instant messaging client, haven’t really used/needed)
• Twittelator (twitter client)
• JawBreaker (game)

I also have a link on the apps page(s) to take me to the Yahoo! Olympics pages to the Medal count and latest news from the 2008 Beijing Games. So that I can keep up with the Olympics.

Nit-piks

• Installed Apps are stopped when you switch to “home” or other app (Makes Pandora use a little less than ideal…. the iPod app, allows you to keep the music going)
• Safari can only really have 8 windows open at once (this is probably a good thing, and forces me to bookmark or email off pages that I am reading and want to keep open longer). Just not an obvious limitation until you run into it… and you can’t open any more links because you hit the max “window” count of Safari.
• Camera app, button location for taking the picture is centered right above the “home” button…. and I invariably hit “home” instead of take a picture. So then I have to wait for the camera app to start up again before I can take the picture I wanted (this time being careful to press the button on the screen and not the “home” button). This is probably just a “getting used” to the device quirk, I hope.
• switching between landscape and portrait mode isn’t flawless…. either it doesn’t switch or it takes longer than I think it should to realize I wanted it to switch to landscape mode.
• Can’t get ipod/pandora music out via bluetooth to my Motorola S9 headset. Apple seems to have decided that the only time you need bluetooth audio is while on a phone call. So there is no A2DP or AVRCP functionality in the bluetooth stack on the iPhone 3G.
• The vibrate feature doesn’t seem to be “enough” to realize there is an incoming call. I am not sure if it is me, or something with the phone, but I have missed more calls with this phone in two weeks than I ever did with my HTC 8125. And I have always left my phone in vibrate… so I thought I was “trained” to respond to the vibration. Possibility is the issue isn’t the phone but more likely the case. Another possibility is that it is actually the reception with 3G and this phone…. and I am not getting the call through… but later getting the notification I missed the call (and new voicemail). I am going to be watching this one more closely, and may need to turn on the ringer for a while to see if I can pinpoint the cause.

So all in all, it is a great device and offers me a number of features/functionality that make me more productive in those “in-between” moments and also a little more connected. The reception/missed calls issue is really the only significant issue and I am hopeful that it can be resolved with placement of the case, or very low ringer. I am hopeful that Apple will consider implementing more bluetooth functionality, as well as the ability to have *some* apps at least run in the background so that you can multitask more on the device. Otherwise, I am very happy with my new iPhone.
