UPDATE: Not anymore. It seems that only emails sent by the web server were delivered using qmail. After seeing this post, they replaced it with AXIGEN. See the comments below (romanian). It’s nice to know that you can make a difference.

Gecad is the company that produces the AXIGEN email server.

AXIGEN is a secure & powerful mail server which includes services such as SMTP / POP3 / IMAP / WebMail / WebAdmin with multiple AntiVirus and AntiSpam protection, allowing system administrators to have full control of the email traffic

After seeing Arny’s comment here [RO], I decided to go on the AXIGEN site and request an evaluation. When I got the email, it’s source looked like this (email addresses edited) :

So, they indeed use qmail. Why don’t they use their own email server? More important, why others should use their commercial product if Gecad uses an open source mail server? Is AXIGEN this bad? :P
Scuze pentru cititorii români, am zis că merită să citească despre asta un public mai larg ;)
