Horde unable to send an email with an attachment over 1MB

Hello Friends,

How are you?

Today I am going to tell about a new bug in Horde. You normally get this issue while sending mails.


Now-a-days, if you try to send an email using Horde webmail client with an attachment larger than 1 MB, you will get below error message:


There was an error sending your message:
only RSET accepted now




Please be informed that it is a known Horde bug and it has already been fixed by Horde. So it just needs to get it into cPanel upstream.

cPanel team are aware of this issue and they are working on this to resolve this as soon as possible.

Please use Roundcube or Squirrelmail to send emails with an attachment(s) 1MB in size or larger to avoid such issue for now.

Hope this help you. 🙂

Thank you.
