我已经安装了siwapp发票软件。它安装成功，但当我尝试使用定期配置文件或甚至向我的客户发送发票时，出现错误说：
Warning: fsockopen() [function.fsockopen]: unable to connect to localhost:25 (Connection refused) in /home/olepress/public_html/my/lib/vendor/symfony/lib/vendor/swiftmailer/classes/Swift/Transport/StreamBuffer.php on line 233

我试图搜索它，有很多问题类似于我的问题，但我不太确定我们是否使用相同的软件。试图玩这个软件的源文件，我发现这个配置文件包含：

我在这里错过了什么吗？我该如何解决这个问题？

检查该应用程序的配置：您必须配置要使用的邮件服务器（smtp服务器）。在使用其他软件时，为其提供发送邮件的服务器的地址。
答案 1 :(得分：0)
如果您使用的是linux，请尝试在服务器上安装sendmail，（debian / ubuntu sudo apt-get install sendmail，（rhat / centos yum install sendmail）。
如果您拥有Gmail或ISP等外部SMTP服务器的凭据，则应该能够在找到的配置文件中指定主机详细信息和凭据，请参阅sending mail in siwapp的文档。
您可以使用类似于以下配置的SMTP：
prod:
...
mailer:
param:
delivery_strategy: realtime
transport:
param:
host: smtp.gmail.com
port: 465
encryption: ssl
username: your_gmail_username@gmail.com
password: your_gmail_password
要使用PHP sendmail，请使用以下配置：
prod:
...
mailer:
param:
delivery_strategy: realtime
transport:
class: Swift_MailTransport
要编辑的配置文件是siwapp/config/factories.yml
希望有所帮助。

我知道这个帖子已经老了，但我终于找到了解决这个非常严重错误的方法。
siwapp的安装说明有点......很多，整个画面很难得到。我已经平均编译了这些笔记
将factories.yml文件复制到配置文件夹
cp <siwapp_root>/apps/siwapp/config/factories.yml <siwapp_root>/config/factories.yml
修改您的产品部分
prod:
...
mailer:
param:
delivery_strategy: realtime
transport:
param:
host: smtp.gmail.com
port: 465
encryption: ssl
username: your_email_address@gmail.com
password: your_password
替换地址和密码的值。
将缓存清空/ cache / *（但不要删除目录本身！）以删除旧配置。我之前遇到过这方面的麻烦，所以建议您最好备份缓存目录......
tar -czf siwappcachebkp.tgz <siwapp_root>/cache/*
要手动配置电子邮件，如果由于某种原因重建缓存失败，则需要专门修改此文件：
<siwapp_root>/cache/siwapp/prod/config/config_factories.yml.php
在文件的末尾，您会发现硬编码到地图的邮件连接详细信息;输入正确的值，你就会好起来。
