My mail server is a postfix one: it works well with other cms like egroupware or xoops.
Moreover, when i try to register a new user, the mail is correctly send.
Nevertheless the feedback form doesn't work: on the server, i have the following error message

connect from localhost.localdomain[127.0.0.1]
Nov 18 21:24:26 fedori postfix/smtpd[31170]: disconnect from localhost.localdomain[127.0.0.1]
Nov 18 21:25:00 fedori postfix/smtpd[31147]: timeout after DATA from localhost.localdomain[127.0.0.1]

After doing some research on the net, i found i am not the only one: I must add that my vezPublish version is 4.0.1 so the issue quote about the 4.0.0 version should not be involved ...

Regards

Arnaud

Steps to reproduce

Install ezPublish using SMTP parameter for mail.
Go to Contact (feedback form) and test it !
