Swiftmailer at 1and1 hosting

Question

I have troubleshooting with sending emails at 1and1 hosting.

I use swift mailer lib message I receive is stream_socket_client(): unable to connect to mrvnet.kundenserver.de:0 http://mrvnet.kundenserver.de:0 (Connection timed out).

Does anyone have similar troubles? Any solution?

PS. At my localhost everything is OK.

Answer 1

I fix SMTP after contact with their support team.

SMTP parameters:

HOST: mrvnet.kundenserver.de
PORT: 25
AUTH: without auth

Answer 2

Contacted support, they asked me do not use encryption (neither ssl nor tls, both not acceptable), so my options are:

host: smtp.1and1.com  
port: 25    
login: somemail@somedomain.com    
passwd: somestrongpassword=)      

as you may mention i use 1and1's mail (same settings for gmail would not work)
