如果使用云服务器搭建邮箱服务器的话，根据相关规定。需要申请开通25端口，阿里云管控很严格，所以我使用的是自己的IDC机房服务器搭建，如果使用电信的网络需要申请开通25端口
1、关闭防火墙
2、关闭selinux
3、内网IP ：192.168.2.222 公网IP 221.12.155.245

配置证书：
安装使用阿里云免费ssl证书脚本
https://www.itgeeker.net/zimbra-8-x安装使用阿里云免费ssl证书脚本/
首先当然要去阿里云申请的ssl证书下载其他类型证书，解压缩后有两个文件上传到相应目录，这里是/opt/zimbra/ssl/aliyunssl/，文件名类似18131-domain.key和.pem
对比Let’s Encrypt和Wosign的证书，这里会涉及到转换阿里云的RSA密钥到PKCS#8的格式，两者的区别，在于开头和结尾的内容。zimbra是不能验证RSA秘钥的
我们可以通过openssl命令把阿里云的私钥转成zimbra能接受的格式。
openssl pkcs8 -topk8 -inform PEM -in 18131XXXXXXXXX.key -outform PEM -nocrypt -out privkey.pem
完整脚本如下：
#!/bin/bash# Note: create by itgeekerdomain=mail.itgeeker.netsu - zimbra -c 'zmproxyctl stop'su - zimbra -c 'zmmailboxdctl stop'mkdir /opt/zimbra/ssl/aliyunssl/echo "up load aliyun ssl other to this folder first !!!!!!!"cd /opt/zimbra/ssl/aliyunssl/openssl pkcs8 -topk8 -inform PEM -in 18131XXXXXXXXX.key -outform PEM -nocrypt -out privkey.pemmv 1813131_mail.geekerconsulting.com.pem cert.pemchown zimbra:zimbra /opt/zimbra/ssl/aliyunssl/*su - zimbra -c 'cd /opt/zimbra/ssl/aliyunssl/ && /opt/zimbra/bin/zmcertmgr verifycrt comm privkey.pem cert.pem 'echo "Backup Zimbra SSL directory"cp -a /opt/zimbra/ssl/zimbra /opt/zimbra/ssl/zimbra.$(date "+%Y%m%d")echo "Copy the private key under Zimbra SSL path"cp /opt/zimbra/ssl/aliyunssl/privkey.pem /opt/zimbra/ssl/zimbra/commercial/commercial.keyecho "Final SSL deployment"su - zimbra -c 'cd /opt/zimbra/ssl/aliyunssl/ /opt/zimbra/bin/zmcertmgr deploycrt comm cert.pem'echo "restart zimbra"su - zimbra -c 'zmcontrol restart'

https://gist.github.com/alanljj/2f90ca543dc2f2e45319ac13c30bbf72
验证zimbra ssl证书命令：
su - zimbra -c '/opt/zimbra/bin/zmcertmgr viewdeployedcrt'
更新
通过上面的方法虽然没有提示任何错误，但可能无法更新证书，使用验证命令，仍然会显示老的证书。那么就需要以下的复杂流程了。
zimbra证书的三个文件，目录/opt/zimbra/ssl/zimbra/commercial/：
- commercial_ca.crt
- commercial.crt
- commercial.key
zimbra ssl证书制作方法：
commercial_ca.crt – 阿里云下载证书1813131_domain.pem的第二部分，也就是第二个—–BEGIN CERTIFICATE—–到—–END CERTIFICATE—– 也就是中级证书(mid-digicert-ca) + 根证书（root-digiert-ca）
两者中间不能有空行
阿里云免费ssl的根证书分享，不同发证机构根证书会有所不同：
-----BEGIN CERTIFICATE-----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-----END CERTIFICATE-----https://gist.github.com/alanljj/26b12b591173b3ba7c3c51edea09cad6
commercial.crt – 1813131_domain.pem的第一部分，也就是第一个—–BEGIN CERTIFICATE—–到—–END CERTIFICATE—–部分。
commercial.key – 就是1813131_domain.key，用上面的RSA密钥到PKCS#8 转换方法先转换，然后改名字就可以了。
开始部署
上传三个文件到/opt/zimbra/ssl/zimbra/commercial/目录，上传前检查、检查、再检查是否已经正确，如果老的文件已存在，先删除老的三个文件（技术奇客有碰到未删除，生成的文件格式不对导致无法更新ssl证书的情况）
验证证书。进入/opt/zimbra/ssl/zimbra/commercial/目录后，使用zimbra用户执行：
/opt/zimbra/common/bin/openssl verify -CAfile commercial_ca.crt commercial.crt
部署证书。 使用zimbra用户执行 ：
/opt/zimbra/bin/zmcertmgr deploycrt comm commercial.crt commercial_ca.crt
重启zimbra服务。
su - zimbra -c 'zmcontrol restart'
查看新证书。
su - zimbra -c '/opt/zimbra/bin/zmcertmgr viewdeployedcrt'
