sendMail | 批量发送钓鱼邮箱

I'm using nodemailer for email submission and running from my localhost. I have email services created manually in the following dir /api/email/services/Email.js

I'm trying to send verification emails when someone fills a form on my website and I'm achieving this using nodemailer.

And my node.js code looks like this:

I have the following code used to send e-mail with attachment, Python 3.6. It works fine, i (somemail@other.com) can receive the email, when i open the mail i see the CC recipient is there, too. But the CC recipient hasn't received the E-Mail. When i look at postfix logs, i see that mail was sent only to me, it was not attempted to send to CC recipient (cc-somemail@other.com)

When i try to send E-Mail from roundcube, hosted locally where the mail server is located, using same text, subject, attachment, the mail is received just fine by both of us.

Im really stuck here. Ive learnt how to use Selenium to scrape a price and in the above example it is for a fuel / gas / petrol website. I can get the price to print in my Terminal:

print("Best Petrol Price in Perth today is:", elem.text)

Though I am stuck in how to reference that price into the body of an email - Im using smtplib and Gmail. Credentials redacted and emails replaced with dummyholders.

Here is my code:

I have an AWS Amazon Linux 2 box. I am using a python script (Python 3.7) to send an email using Sendgrid as the SMTP service. I can send the email using $ python3 send_email.py but, when I use crontab ($ crontab -e then * * * * * python3 ~/apps/send_email.py), the error in the log file /var/log/cron is (CRON) EXEC FAILED (/usr/sbin/sendmail): No such file or directory. The crontab is working as expected (I've tested other cron commands and they work fine), but the email part is what's not working.

Here's what I've tried to fix it:

1. Run the command as a root crontab (ie $ sudo crontab -e)
2. Run the the crontab as a user crontab (ie $crontab -e)), but with sudo python3 ... in the crontab command.
3. Add the path directory at the top of the crontab file in case those directories couldn't be resolved
4. Installed Postfix to install something in the /usr/bin/sendmail directory but, since I don't need it to run the Sendgrid-powered email using $ python3 send_email.py, I'm not sure why I would need it through cron. I could be totally wrong on this, though. With Postfix installed, it resolves the (CRON) EXEC FAILED (/usr/sbin/sendmail): No such file or directory error in the cron log - the log entry in that case is (ec2-user) CMD (python3 ~/apps/send_email.py) - but I don't receive an email. Probably because Postfix isn't configured for the SMTP I'm using (Sendgrid).
5. (EDIT) I have configured Sendgrid to work with Postfix via the Sendgrid docs but it still won't send me an email although it looks like nothing is erroring out in the Postfix logs...

Hope you are well. I am in the middle of working on an application that uses express and nodemailer. My application sends emails successfully, but the issue is, is that I cannot send the emails off one at a time in a manner that I'd like. I do not want to put an array of addresses into the 'to' field, I'd like each e-mail out individually.

I have succeeded in this, however there is an issue. It seems Microsoft has written some kind of limit that prevents applications from having more than a certain number of connections at a time. (link with explanation at end of document of post.)

I have tried to get around this by a number of expedients. Not all of which I'll trouble you with. The majority of them involve setInterval() and either map or forEach. I do not intend to send all that many e-mails - certainly not any to flirt with any kind of standard. I do not even want any HTML in my emails. Just plain text. When my application sends out 2/3 e-mails however, I encounter their error message (response code 432).

Below you will see my code.

• As you can see, I'm at the point where I've even been willing to try adding my incrementer into setInterval, as if changing the interval the e-mails fire at will actually help.
• Right now, this is sending out some e-mails, but I'm eventually encountering that block. This usually happens around 2/3 e-mails. It is strangely inconsistent however.

This is the first relevant section of my code.

I am using nodejs with nodemailer for sending emails to users.

I have a list of users like this :-

I'm trying to work out how to fix this ActiveMQ Artemis error.

Seems the occasional message is too big for SimpleString, and isn't sending, and it goes to the DLQ.
