问题描述
我正在尝试使用smtp-sink来捕获mail命令（var namespace = XmlService.getNamespace("http://www.w3.org/2005/Atom");
var entries = root.getChildren("entry",namespace);
）发送的邮件。
这在我的工作计算机（RHEL7）上正常工作：
mailx但是，在GitHub Actions（Ubuntu）上，电子邮件仅绕过# Set the env variable `smtp`,which the `mail` command will use:
$ export smtp='localhost:8025'
# Set up the smtp-sink process listening on the port above:
$ smtp-sink -D 'mail_log.txt' -M 1 localhost:8025 1 &
# - will dump to mail_log.txt
# - "-M 1" makes it quit after receiving 1 email
# - the final "1" at the end is the backlog,doesn't matter too much
# - The "&" at the end sets the process up in the background
$ mail -s 'Test' <username> <<< 'This is a test'
$ cat mail_log.txt
X-Client-Addr: ipv6:::xxxx:xxxx:xxxx:xxxx
X-Client-Proto: SMTP
...
Received: from <host> ([ipv6:::xxxx:xxxx:xxxx:xxxx])
by smtp-sink (smtp-sink) with SMTP id xxxxxxxx;

From: <username>@<host>
To: <username>
Subject: Test
Message-ID: <xxxxxxxx.xxxxxxxxxxxxxxxx%<username>@<host>>
User-Agent: Heirloom mailx 12.5 7/5/10
...
This is a test
并最终进入邮箱。这是工作流程：
smtp-sink为什么SMTP捕获在GitHub Actions运行器上不起作用？
我还尝试使用Python的smtpd module代替jobs:
test-smtp-sink:
runs-on: ubuntu-latest
steps:
- run: sudo apt-get update && sudo apt-get install -y bsd-mailx
- run: |
export smtp='localhost:8025'
smtp-sink -D 'mail_log.txt' -M 1 "$smtp" 1 &
mail -s 'Test' runner <<< 'This is a test'
- run: |
mail # Checks mailbox - should be empty but instead contains the test email
cat mail_log.txt # File doesn't exist
：
smtp-sink再次在我的本地计算机上运行，但在GH Actions上，电子邮件绕过了该电子邮件，并再次出现在邮箱中。
