    Cannot connect with smtp, my test or send always fails

See also Web hosting configurations

Some web host limit the use of SMTP. First thing to do is to ask to your local technical support.
Do they provide full access to smtp and if so are there specific settings ?
If not, do they provide access to SENDMAIL, so use the addon mailpress_connection_sendmail
If not, do they provide access to native PHP Mail, so use the addon mailpress_connection_phpmail
If not, few chances you can successfully use MailPress.

So you have read everything, and want more ...

There is still a lot of information to read at the plugin wiki.

I am interested on how you use MailPress, what is(are) your favorite addon(s), how many mails you send per month, if your use of MailPress is so specific that you want to tell us, you may have developped your own addon. 

Even if there is a "Donate" button on the plugin page, MailPress is totally free so share your tips, tricks, addons ... everything that could help ! 

Thanks for your support and ....
