Hello,
I have a problem with sending emails through Roundcube, I get error:

SMTP Error (-1): Connection to server failed.

What could it be?

I've read that it could be problem with port 587, should be open. I've checked:

netstat -tlpn | grep :587
tcp        0      0 0.0.0.0:587             0.0.0.0:*               LISTEN      1889/smtpd

But then I've checked also port 25 and I get:

tcp        0      0 111.xxx.xxx.xxx:25        0.0.0.0:*               LISTEN      2574/smtpd
tcp        0      0 222.xxx.xxx.xxx:25        0.0.0.0:*               LISTEN      15169/master
tcp        0      0 333.xxx.xxx.xxx:25        0.0.0.0:*               LISTEN      15169/master
tcp        0      0 444.xxx.xxx.xxx:25        0.0.0.0:*               LISTEN      15169/master
tcp        0      0 555.xxx.xxx.xxx:25        0.0.0.0:*               LISTEN      15169/master

Because I have 5 domains with 5 different IP, sholudnt resualt for 587 look the same? For each my IP? If so how can I set this?

Re: Roundcube SMTP Error (-1): Connection to server failed.

I don't see any error's related to roundcube/imap in mail.log

Yes, the service iRedAPD is running:

# service iredapd start
iredapd is already running.

What about this error in mail.err (my last post)?

Re: Roundcube SMTP Error (-1): Connection to server failed.

Maybe smtp service is not running, or not running well and cannot handle request correctly.
Without detailed log, i cannot help much, sorry.

Dear Friend,

I have exactly the same problem. I have upgraded my ubuntu server from 14 to 16 and I had to upgrade roundcube in order to have it functional again. i am unable to send emails now and I have this in mail.log:

SMTP Error: Connection failed: Failed to connect socket: Connection refused in /opt/www/roundcubemail-1.1.5/program/lib/Roundcube/rcube.php on line 1648 (POST /mail/?_task=mail&_unlock=loading1484956101491&_lang=en_US&_framed=1&_action=send)

Can You help me?

Re: Roundcube SMTP Error (-1): Connection to server failed.

I have just checked that receiving mails also doesn't work... sad Connect to the server via email client also not possible... There is nothing listening on ports 465 and 587 for example. I have checked netstat.

Re: Roundcube SMTP Error (-1): Connection to server failed.

Check if there's any error / warning / fatal message in Postfix log first.
