Make sure you have SMTP setup.

... if you don't use SMTP mails are sent by PHP mail function. Most spam filters consider mails sent by PHP as spam.

Have you checked if your server IPs are on spam lists?

main.inc.php

change ...

// add this user-agent to message headers when sending
$rcmail_config['useragent'] = 'Roundcube Webmail/'.RCMAIL_VERSION;

... maybe it helps.

are you sure your identity is setup correctly in RC, also may be check in the SMTP server logs and see if there is anything different when RC sends a message and when Outlook does.

Outlook Marks RC Mail as Junk
« Reply #10 on: September 24, 2010, 11:15:19 PM »
When I send mail from RC, the mail is filtered into the Junk folder in Outlook. If I send the mail from Outlook or Thunderbird the mail goes into the Inbox in Outlook. When my RC implementation goes live and all my RC users have this problem with their Outlook mail recipients, I'm sure to hear about it. This is a big issue since so many people use Outlook.

This seems like the right thread for this issue; however, I'm not getting the same errors mentioned here. The mail sends clean without errors. Any ideas?

you need to find out why outlook is putting it in the spam folder, what rule is the mail breaking?

Microsoft doesn't document their Junk filter rules as far as I can tell. I think it is a blackbox so as not to help spammers. Correct me if I'm wrong. I may have missed something out there.

I'm hoping someone else resolved this same problem and can shed some light on the subject.

After some experimentation, I was able to determine that if I send in plain text the e-mail will go into Outlook's Inbox.

This means that there is a problem with how RoundCube is formatting its html messages. This could be caused by incomplete CSS definitions or other reasons. I don’t know. I think since this is a problem that could potentially cause issues with so many RC users, it should be confirmed with other installations and investigated to determine the root cause. Do I need to report this somewhere?

Note: I also discovered that Outlook does cache the status of a sender for a little time so configuration changes need to be spaced over time.

Is there a way to send a message as both html and plain text?

When you send a html email it include a plain text copy for email clients that don't read html. When I send email from RoundCube to Outlook its goes through just fine.
