##How to create postfix SAN certificate
Create SAN (multi-domains) certificates for a postfix configuration
Edit postfix_pem_path and mail_server and deploy ssh key accordingly.
I should write a blog article once I have time, meanwhile do not hesitate to ask questions on the repo
Usage:
```
./create-cert-postfix domain1.tld domain2.tld domain3.tld
```
