我在本教程中使用了此Gmail设置，并且效果很好：

# Email configurations: (Sendmail + Gmail)
Login to your gmail account, enable imap.
Let the access here first: https://www.google.com/settings/security/lesssecureapps
Go to: https://accounts.google.com/b/0/DisplayUnlockCaptcha
sudo apt-get install sendmail mailutils sendmail-bin
folder and configuration file::
sudo mkdir -m 700 /etc/mail/authinfo/
sudo su
cd /etc/mail/authinfo/
sudo nano gmail-auth
AuthInfo: "U:root" "I:myemail@gmail.com" "P:mypass"
the hash map:
sudo makemap hash gmail-auth < gmail-auth
configure your sendmail:
sudo nano /etc/mail/sendmail.mc
paste just before the first MAILER definition line: (` and ' inconsistency is OK!)
define(`SMART_HOST',`[smtp.gmail.com]')dnl
define(`RELAY_MAILER_ARGS', `TCP $h 587')dnl
define(`ESMTP_MAILER_ARGS', `TCP $h 587')dnl
define(`confAUTH_OPTIONS', `A p')dnl
TRUST_AUTH_MECH(`EXTERNAL DIGEST-MD5 CRAM-MD5 LOGIN PLAIN')dnl
define(`confAUTH_MECHANISMS', `EXTERNAL GSSAPI DIGEST-MD5 CRAM-MD5 LOGIN PLAIN')dnl
FEATURE(`authinfo',`hash -o /etc/mail/authinfo/gmail-auth.db')dnl
Now rebuild the sendmail configuration and restart it:
make -C /etc/mail
restart sendmail
Configure Sharetribe to use Sendmail:
exit root user CTRL+D
nano ~/sharetribe/config/config.yml
mail_delivery_method: "sendmail"
但是，我想要通过电子邮件而不是Gmail品牌的品牌。因此，我继续更改上述代码，以便能够使用SMTP发送电子邮件：
mail_delivery_method: "smtp"
smtp_email_address: "myuser@example.com"
smtp_email_port: 465
smtp_email_domain: "smtpserver.example.com"
smtp_email_user_name: "myuser@example.com"
smtp_email_password: "mypass"
尽管我尝试了很多事情，但它行不通。服务器是Digitalocean VPS，但电子邮件是由DNS配置中的主机处理的。是的，我的品牌电子邮件可以与Outlook一起使用。这也是防火墙配置：

这是一些调试信息，可以查看我尝试发送电子邮件时会发生什么：

那么如何使用SMTP从品牌域发送电子邮件？
或我可以跳过所有这些，并尝试配置SendMail以使用我的品牌域而不是Gmail？
我正在使用品牌电子邮件。我可能会看到港口可能的问题。检查此行
# we have `:enable_starttls_auto => true` and we use 465. It works
smtp_email_port: 465
与:enable_starttls_auto => true一起，我们也有:ssl => true的生产。RB
在我们的情况下，我们使用Zoho，因此我们转介了此文档
传出服务器名称：smtp.zoho.in
端口：465带SSL或
端口：587带有TLS
请为您的提供商检查此部分。您可能需要尝试为非SSL的587端口。
