Zurmo CRM a free open source CRM system supports (as of Jan 2017) only SMTP outgoing mail.
on YOUR_CRM_DOMAIN/app/index.php/emailMessages/default/configurationEditOutbound I set the following attributes. The values in the parenthesis are taken from 1and1.com help page "E-mail Software Setup Credentials"
Host * (imap.1and1.com)
Port * (587)
Username (e.g. user.email@user.domain.com)
Password (e.g. mypassword)
Extra Mail Settings (tls)
Send a test email to (e.g. random.user@gmail.com)
When attempting to send the test outgoing mail, I get the error message
Message failed to send
Error Code: 0
Error Message: Connection could not be established with host smtp.1and1.com [Connection timed out #110]
What should be the correct values to make Zurmo CRM email work on 1and1.com shared hosts?
