I’m here to write about some fake MTA packages, not mail servers.
Over the years, I’ve used three mail transfer agents on the same server that hosted my websites, one real and two fake. The first one was real, Postfix. The second was sSMTP and the last one I used was msmtp. A fake MTA is limited and it should be limited if it’s only going to be used for comments or contact form messages on a non-professional website.
My comments go through Disqus, so there’s no issue with them. All of my contact form messages were routed through my Gmail account. I no longer use a fake MTA or any kind of mail server. I’m now using a “mailto” link, dressed up with the MailtoUI interface. I was getting too much spam directly targeting my contact form on my contact page.
I do my web development on Windows 10 these days and I found a fake sendmail for Windows shortly after I installed the other software packages I needed. When testing, I found it worked as well as msmtp on Linux.
Of the three, only msmtp and sendmail for Windows are being actively developed and updated. You can find an updated version of sendmail at GitHub. The sSMTP fake MTA hasn’t been updated in a while (I switched for that reason) but I can’t tell you when without installing it and I don’t want to do that.
I don’t get enough contact email to matter these days, therefore I don’t want to use full-fledged mail server ever again.
