dovecot – Postfix: With SASL on Thunderbird can connect to Postfix but Node.js app can’t. With SASL off the reverse is true. Why is this?

Environment: Postfix 3.3, Dovecot 2.2, Node.js – Postfix/Dovecot is running next to a Node.js app inside of a Digital Ocean Droplet.

Question: With SASL on Thunderbird can connect to Postfix but Node.js app can’t. With SASL off the reverse is true. Why is this?

Background: With these 4 lines added to Thunderbird connects up to Postfix/Dovecot and sends and receives normally.

smtpd_sasl_type = dovecot
smtpd_sasl_path = private/auth
smtpd_sasl_security_options = noanonymous
smtpd_sasl_auth_enable = yes

Unfortunately with SASL turned on the Node.js app cannot connect to the server. It produces this error when Node attempts to send.

auth(3552): pam_unix(dovecot:auth): check pass; user unknown
auth(3552): pam_unix(dovecot:auth): authentication failure; logname= uid=0 euid=0 tty=dovecot rhost=
postfix/smtpd(3540): warning: unknown( SASL PLAIN authentication failed:

On the flip side when those 4 lines are commented out in Node.js can connect up and send mail without a problem.

Unfortunately with SASL turned off I lose the ability to send and receieve email in Thunderbird. I get this error in an alert box in Thunderbird.

An error occurred while sending mail. The mail server responded:
454 4.7.1 <>: Relay access denied.

applications – How do I enable a forced stop & disabled Bluetooth Share app on Android 4.0.4 (Ice Cream Sandwich)

Over enthusiastic to disable many distracting apps on my Sony Xperia U (ST25i) I went “settings>apps>all” and disabled away. Where no disable option was available, I clicked on force stop. With Bluetooth Share I stupidly took it to be a social networking app and disabled it, later force stopping it. Dumb, I know, but how do I get it back? I’m fairly new to all of this, obviously, so please be very specific in responding. Many thanks.

iphone – Xcode Error: Unable to install app (Error Code: Code: -402620383)

I am using my free developer account (AppleID) for learning to develop iOS apps with Xcode. My iOS version is 13.5 and I am running Xcode 11.5 on Mac Catalina version 10.15.4.

I created a simple app that prints some text on the screen on my iPhone X and when I tried to run the app, Xcode returned an error: “Unable to install app”, error code: -402620383. When I clicked for more details, I got a more detailed description of the error: “The maximum number of apps for free development profiles has been reached.”

After much search on the Internet, I tried the following fixes and none of these worked:
1. Creating a new apple ID and link that to Xcode.
2. Unpaired my iPhone X/deleted the provisioning profiles in windows/devices in Xcode.
3. Checked in the windows/devices and simulators and there were no apps installed.

The interesting thing is that I tried running the app on my wife’s iPhone X (running iOS 13.5 as well) and it worked. Digging a little deeper, I noticed device management under settings/general is missing in my iPhone but present in my wife’s iPhone. The profile of the app I was trying to install in device management. Maybe that is the cause of the problem. I really don’t know what to do and would appreciate help on this, thanks!

If someone stole my symantec VIP credential ID, would they be able to generate the same one-time passcode as the app does?

Let’s say I’ve installed the Symantec VIP app on my device. If someone stole my Symantec VIP credential ID, would they be able to generate the same one-time passcode (OTP) as the app does?

“Additional content download” requested on some higher spec android phones after reinstalling/deleting game app data- what criteria would there be?

I had two phones both fine and then something changed so that on the higher spec it has to download additional content which is a real pain as it takes at upto and over 10mins depending on network and cannot use mobile data. The older spec has no extras requested, the curious thing is the game started offering a low Res version but my low spec by default uses the standard res version.

Im wondering what it is about the low spec that tells either Google play or the app developer what the phone can handle. I need to replace the low spec due to a broken port but would like to get a faster phone which still avoids this additional content.

The game is large, CSR2 and the low spec has 2GB ram, 16GB storage (no media is stored, no extra apps besides the game so space isnt an issue) running only android 6 with no more updates only security.

Ive asked game support and all theyve said is they recommend 2GB ram or more, android4.4 or better and 3GB or more available space to play the game (nothing about this additional content).

How do I find out what app is using a specific shortcut, in macOS Catalina

I want to use a specific shortcut to archive my Mail on macOS, Command+Shift+A, but even thought it lets me add it in the keyboard shortcuts section, it doesnt do anything when I go in Mail. i got a feeling some third-party app is using it, or something else, but for the life of me I can’t find it.

Anyone come across this and have any ideas?
