Hello!
I'm a Senior Linux Admin, with an background in email delivery. I have been working with Linux servers for the past 20+ years, and have deployed, configured and managed quite a number of email servers.
I can troubleshoot and, as you put yourself, make it work no matter the difficulty of the issue or the price to be agreed, If too complex.
I'm looking forward to the opportunity of doing this job.
Best regards,
Frederico
