Hi i have installed manually the last version of roundcube due to i cant have the latest version by cpanel because my server have centos 6 and cannot update to the latest cpanel version that comes with the new rouncube version. The situation is that when i try to forward an email with ***SPAM*** i cannot deliver it, and the rouncube window remains on Sending... and finally get a timeout or recieve a message like: Error SMTP: 550 This message was classified as SPAM and may not be delivered. A rare thing is thats when i login to the stock roundcube (the old one) that is on my cpanel server and try to forward the same message that i'm trying to forward on the manually installed roundcube by me, and the message is sent with no problem. Is possible to configure exim to avoid scan outgoing messages for spam? I know that rouncube is a third party software but it's very rare that the old rc that comes with cpanel con forward messages flagged as spam and the new one installed cant.

  Hi, First - I cannot recommend enough that you should upgrade as soon as possible Centos 6 EOL is just around the corner and nowadays - depending on your setup - it's relatively easy migrating to a new server. Now to your issue: - How did you install and configure Roundcube? - In your Exim Configuration Manager, if you look under Apache Spamassasin tab, have you enabled outgoing spam scanning? (Disabled by default)?

  I don't have much experience with customized webmail installs on cPanel - but maybe replacing the server names with "localhost" will help. Just a guess. Also, I can see that you have enabled "Do not forward mail to external recipients based on the defined Apache SpamAssassin". Have you tried disabling that?

  Ok - probably because of SSL/TLS verify (as it cannot verify localhost). Did you try disabling the "Do not forward mail..." ?

  HI @samuelmf Sorry to hear you're still having this trouble. Because you installed a custom version of roundcube the installation is not something that is supported by cPanel and its behavior will be completely different than cPanel's roundcube as it's not integrated. What I would imagine is happening is Roundcube's own spam filtering or a plugin is looking at X-Spam headers and making decisions on allowed actions based on their presence. What I would suggest you do to troubleshoot the custom roundcube installation further if you're unaware which portion of the software is doing this is to go through their support documentation here: They also have a mailing list here:

  @cPanelLauren seems that i've discovered the cause for the problem when forwarding messages, the problem apparently is caused by wordfence wordpress plugin, i've disabled it and now i can forward emails. Just for test pourposes i've enabled it again and the hang "sending..." message back again and get timeout. I disabled wordfence and now i'm able to forward messages I will look on the wordfence rules to put my domain on whitelist
