我在 ubuntu-nginx vps 服务器的公共 html 文件夹中托管多个域。我目前已将 ssmtp.conf 文件设置为从其中一个域（例如 example1）成功发送邮件。
是否有任何方法可以对 ssmtp.conf 文件进行一些修改，以便也可以从属于其他域的电子邮件帐户发送邮件？例如，example2.com。
提前致谢。
我当前的 ssmtp.conf 文件如下所示：
#
# Config file for sSMTP sendmail
#
# The person who gets all mail for userids < 1000
# Make this empty to disable rewriting.
[email protected]
# The place where the mail goes. The actual machine name is required no
# MX records are consulted. Commonly mailhosts are named mail.domain.com
mailhub=smtp.example1.com:25
# Where will the mail seem to come from?
rewriteDomain=example1.com
# The full hostname
hostname=example1.com
# Are users allowed to set their own From: address?
# YES - Allow the user to specify their own From: address
# NO - Use the system generated From: address
FromLineOverride=YES
