Did you read the reject message and do what it suggests? Most reject messages aim to let legitimate senders figure out how to resolve the problem while still making life difficult for spammers.
I see your ISP is Digital Ocean. There are several large providers who reject all email from Digital Ocean. You may want to search for "Digital Ocean mail server" and other similar terms.
If you're sending from a pingmytag.com email address, your SPF record says you can send from mailjet.com, but not from 178.62.95.5.  Sending all your email through mailjet should avoid the problems with delivery from a Digital Ocean email address.
I hope that helps.

Hello, my emails are not sending or receiving apart from emails connected to my Wordpress site. All emails I try to send bounce back with the following;
SMTP error from remote mail server after MAIL FROM:<services@pingmytag.com> SIZE=1529:
    550 5.7.1 Unfortunately, messages from [178.62.95.5] weren't sent. Please contact your Internet service provider since part of their network is on our block list (S3140). You can also refer your provider to http://mail.live.com/mail/troubleshooting.aspx#errors. [BN1NAM02FT042.eop-nam02.prod.protection.outlook.com 2024-06-10T08:28:48.894Z 08DC875301BE0C92]

I have tried sending emails to multiple different emails to see if it is just an issue with certain emails but all sent emails get returned.

please could somebody help. thankyou

Moiun zusammen,

folgendes Problem. Ich habe meine Synology neu aufgesetzt und die Daten per Backup zurück gespielt. Alles schick soweit. Nun habe ich die Mailstation drauf die per Roundcube die Mails abfragt. Nun zu meinem Problem.

Roundcube fragt die Mails nicht mehr ab.

Senden funktioniert (habe noch einen POP3 im Outlook da kommen die Testmaisl aus Roundcube an). Ebenso wenn ich im Outlook das Konto Teste bekomme ich keine Fehlermeldungen. Aber warum holt Roundcube die Mails nicht mehr ab? Hat irgend jemand eine Idee? Ports sollten passen.

can we add attachments to the roundcube mails
is this possible!?`
can we do so

Hi there,

I have a strange "bug", that a customer can't open a single email with the message
"The message part is too big to process it. [Download]".


I installed many Roundcube instances, so it's not new for me. In this case, also, the newest 1.6.7 version. PHP 8.2, nginx (fpm) with good memory, post and upload limits.

But if I remove in the file:
/program/actions/mail/show.php
this one:


It works on client side again:


Someone has an idea why?
Database -> up to date
Debian 12, PHP-FPM 8.2, nginx + rules -> OK (memory_limit: 128M, upload: 4G, post_max: 6G)
In config: 150M as max. message size
Dovecot/Postfix: Same config like all other servers where it works - if I connect directly to mail servers I see all email messages without problems (for example Thunderbird)
Encoding is also set well...

Thanks and best regards!

I have a postfix / dovecot /roundcube running on a ubuntu 22.04
I have some user which get mail with a false warning on SPAM
=>     [***** SPAM 6.2 *****] xxxx
With a score higher than 4 which is the value I set in the conf.

I have add the mail of the sender in "/usr/share/spamassassin/local.cf"

Quoteshortcircuit USER_IN_WHITELIST       on
shortcircuit USER_IN_DEF_WHITELIST   on
whitelist_from notif-colissimo-laposte.info

reboot the server

But mail from the sender still arrive with a SPAM score higer than 4...

any idea why ?

Thanks

Roundcube only requires PHP 7.3 or greater https://roundcube.net/about/#serverrequirements It will work fine with PHP 8.2.

Roundcube 1.6 should work fine with PHP 8.2 and 8.3 (there might be some deprecation notices in logs with 8.3).

Hello! What version of runcubetail do you have installed?

There are two options to fix everything:
- download the current version of rundcubemail (at the date of the post it is 1.6.7)
- change the line in the installer/chesk.php file (this is approximately line 115) to define('MIN_PHP_VERSION', '8.3.0'), which will force roundcubemail to work with PHP 8.3

Whoops.
I searched and didn't see this post.  So I posted my own thread on it.

I would love to run PHP 8.3, but Roundcube tells me I have to run PHP 8.1.

I feel your pain.
