"P.S. - if you want to see what good code does look like in an MTA, take a glance at the source for exim one day. It is very clear and well structured, I think."
Full of bugs, 2 code execution bugs last year. www.cvedetails.com/product/19563/Exim-Exim.html?vendor_id=10919
Why should software be in a state of permanent development?
"I can't take any of the DJB projects seriously because they're always in a state of permanent abandonment and maintainers are impossible to find. They serve as art pieces more than practical, useful software."
There are plenty of "maintainers", just search for the qmail mailing list, if that is impossible then I'm not sure what to say to you, but what you say is bunk.
"I worked at a hosting company a few years ago that still used qmail (and Apache 1.3, and this was in 2010); there was a slight misbehaviour in qmail which we needed to change, which resulted in one of our sysadmins (who didn't really know C) spending days reading, changing, compiling, testing, and debugging code which, with Postfix, would have been a one-line config change. And who knows if it's robust? He stopped working on it once he had a solution that passed his test without segfaulting immediately."
Anecdotal, please provide a link to the qmail mailing list with evidence.
"The only issue that has the possibility of being legitimate in is the Benghazi stuff. Technically, it could have been a deliberate move to make emails related to Benghazi un-searchable during the investigation. Of course, this only actually matters if those emails contain anything significant/damning, and they probably don't."
Are you saying that she setup a non-gov email so she could make benghazi emails un-searchable before benghazi even happend? CT much?
My whole family uses Ubuntu. There really very little hand holding, it just works. I actually spent more time hand holding with my partner had a Mac. When that machine died, we decided to go back to Ubuntu and a Lenovo thinkpad. It was a good choice.
This is called Unsolicited Commercial Email (UCE), which by definition is spam. If you are sending someone email with hopes to sell them something, it doesn't matter how nice you are, it is still spam. Cold emails are spam.
Call me weird, but I like mybatis over jpa. You can create an xml file with your sql or use a java annotation to define it. Everything else is just pojo after that.
