What is the simplest vertical spacer in Outlook (HTML email)?

Asked 2022-Mar-13 at 11:32

What is the simplest vertical spacer in Outlook (and supported everywhere else)?

I have two elements, one on top of the other, both with display:block. I would like to space them without wrapping either in a table. I want a spacer that I can reuse anywhere with only simple adjustments to its height. I need to be able to set it to specific pixel heights. I also need to be able to override the height with a media query to make it responsive.

smtplib best way to rename multiple emails

Asked 2022-Mar-05 at 11:54

I have an smtplib function that loops through 2 excel files and then opens them and adds them as an attachment. Right now the have generic names, but I thought it would be pretty cool to grab info from the data and use it as the name of the document. For example I wanted to grab their location based on a "Location" column found in a dataframe if Ive filtered by the user.

Goal: Rename 2 documents currently called "File1.xlsx" and "File2.xlsx" to "location_email_reminder1_3-4-2022" and "location_email_reminder2_3-4-2022"

QUESTION

How to setup minimal smtp server on localhost to send messages to other smtp servers

Asked 2022-Feb-05 at 07:42

Honestly, I think I have a fundamental gap in understanding how SMTP works. I can't seem to find a good explanation of what is happening behind the scenes and I think this is preventing me from being able to do what I am attempting to do.

To explain, I'm trying to setup an application which sends notifications to users by connecting to an SMTP server. Fair enough. I figure, since I'm using my own domain, I have SPF/DKIM/DMARC configured, I can add an MX record for the host I set the application up on (my SPF record has the mx keyword to authorize any hosts in my MX records to send/receive mails). Then, I can have that same host run a super lightweight SMTP server that can accept mails from the application, and send them on to recipients.

Almost crucially, I want this server to basically just run on localhost so that only this application can connect and send mails through it, but so that it can't really "receive" mails sent to my domain (I have set the MX priority very low (well, a high number) for this app server). I figure since I'm running my own SMTP server, that I don't really need to authenticate against it (it's running on localhost), just take in any mail and send it on to recipient domains.

When sending on to recipient domains... does the SMTP server need to authenticate to say, the gmail SMTP server as a user in order to send mails over there? That seems weird, since it's not a user logging into gmail to send mails, it's an SMTP server that is authorized within SPF sending mail from my domain (From address from my domain as well) to where ever the app server user's email is based (in this example, the user would be e.g., some_user@gmail.com).

I tried using python's aiosmtpd command-line and telnet to send a mail from test@MY_DOMAIN.TLD to test@MY_DOMAIN.TLD and it didn't seem to deliver the message; I figured aiosmtpd would connect to the preferred MX servers for my domain (my "real" MX's) to transfer the message, which would then put it in my inbox. That didn't seem to be the case, and I'm not sure why.

Exact repro steps, where example.com is my domain, and terminals are running on a box with a hostname listed in my MX records.

It sounds like you want to run a mail transfer agent (MTA) that relays email to remote SMTP servers. An MTA will typically act as an SMTP server to receive messages, and then it will act as an SMTP client when it relays the messages to remote hosts.

MTAs generally operate in two different modes: (1) They will relay messages from authenticated users to remote hosts, and (2) they will receive messages from remote hosts to its users and store them somehow. The combination of those two modes - where the MTA will accept messages from remote hosts and relay them to different remote hosts - is called an open relay and is sure to attract spammers and place your server on spam blacklists.

aiosmtpd is not an MTA or an email relay out of the box - it is merely an SMTP server that will receive messages and do whatever with the messages you program it to do. By default it will do nothing - that is, it will receive the messages and throw them away. If you want to implement an email relay in aiosmtpd, then you need to implement the SMTP client portion of the MTA, e.g. by implementing an aiosmtpd handler that instantiates smtplib.SMTP to connect to remote hosts.

However, if all you want is an email relay, then you most likely don't need aiosmtpd at all - postfix is probably a better choice.

aiosmtpd can be a good choice if you need to implement mailing list software or perform some automation tasks based on incoming emails from e.g. cameras or scanners.

If you want to implement an email relay in aiosmtpd, then you need to ensure that both the software and your server are configured in a way that you don't relay unauthenticated messages from the outside internet.

In the try-catch block, you send a response res.send({ user: user._id }) without stopping the function. The function continues to execute and you try to send another response res.status(200).json({ status: 'OK' });

I'd recommend changing the try-catch block to this:

Under the covers, smtp.SendMail calls smtp.Client.Rcpt for each to recipient. The to slice directs who will actually receive the email. The addressees in the body of the email is purely informational - in fact they don't even need to match the real addressee info.

So to fix your addressing issue, you need to collect all to, cc & bcc addressees:

Install MailDemon

Ensure .NET 5.0 SDK or newer installed.
Download code, open in Visual Studio or VS Code, set release configuration.
Update appsettings.json with your settings. I recommend an SSL certificate. Lets encrypt is a great option. Make sure to set the users to something other than the default.
Right click on project, select 'publish' option.
Find the publish folder (right click on project and open in explorer), then browse to bin/release/publish/netcoreapp and make sure it looks good.
If you don't want to install .NET core, set your publish profile to "self contained".
FTP or copy files to your server.
For Windows, use Firedaemon and set the command to run your .dll or .exe from your publish step.
For Linux setup a service (put binaries in /opt/MailDemon):
Ensure you have setup DNS for your domain (TXT, A and MX record) Setup SPF record: v=spf1 mx -all Setup MX record: @ or smtp or email, etc. Setup A and/or AAAA record: @ or smtp or email, etc. Setup DMARC record, https://en.wikipedia.org/wiki/DMARC Setup DKIM, https://en.wikipedia.org/wiki/DomainKeys_Identified_Mail
Setup reverse dns for your ip address to your A and/or AAAA record. Your hosting provider should have a way to do this.

Hotmail.com, live.com and outlook.com have had an invalid SSL certificate for quite a while now. I've added them to appsettings.json. You may need to add additional entries for mail services with bad certificates.
Mail Demon contains an integrated mail list management website and mail list sending service. In order to use this service, you must setup your appsettings.json file and make some additional optional customization.
Make sure your smtp settings are correct in appsettings.json.
Setup appsettings.json, mailDemonWeb section. Set enableWeb to true. Set the authority to your scheme and host, i.e. https://yourdomain.com. Set your admin user/password. Set google recaptcha keys (https://www.google.com/recaptcha). Set ssl certificate (.pem public and private files along with password).
Use --server.urls parameter to set the kestrel binding for the web server.
Login with https://yourdomain.com/MailDemonLogin. Replace yourdomain.com with your actual domain name. Use the admin user/password from the appsettings.json file. Nothing will show up until you login.
Create a new mailing list using menu at top.
List name is meant to be more like a short variable name, somewhat human readable, but short and unique. List title is what subscribers will see.
Send your victims, I mean subscribers, to https://yourdomain.com/SubscribeInitial/[listname]. Replace yourdomain.com with your actual domain name. Replace [listname] with the actual list name.
Create new templates by selecting lists at the top, then using create template button.
The template name format is [listName]@[templateName] (without brackets). Just like lists, the template name is a short, human readable and unique name.
The template title is NOT the subject of the email, it is just informational for you only.
Full razor syntax, @Html, etc. is supported. The model for the templates is the MailListSubscription class.
Feel free to create and edit templates in visual studio and then paste them into the template text box.
Each template should have a layout. A layout is a template that you will never email, it just wraps other templates. You can name your layout [listName]@[layoutName] (without brackets). You can start with _LayoutMail.cshtml and customize and provide your own css link. You should also provide an unsubscribe link, along with a physical mailing address to comply with anti-spam laws.
Set the layout of your template like this: @{ Layout = "listName@layoutName"; }
To set the email subject, add a  to the body of your template, it will then be set as the email subject. This is required in order to send email. See SubscribeConfirmDefault.cshtml for an example.
To bulk send email from a mail list, select (or create) the template from the list to send, edit it, add your subject and save. Then use the send button to perform the bulk email operation. Errors will be logged.
There are three magic template names that can override the default behavior for a list: SubscribeInitial (see SubscribeInitialDefault.cshtml). This is the initial sign-up form. SubscribeConfirm (see SubscribeConfirmDefault.cshtml). This is the confirmation email with a link to activate the subscription. SubscribeWelcome (see SubscribeWelcomeDefault.cshtml). This is the welcome email to notify of the active subscription, along with an unsubscribe link.
Note that the MailDemon.db file contains all the lists, templates, subscribers, etc. Backup this file regularly!
You can also store your templates in the Views/Shared directory. Follow the same naming convention for a template name
