"RSET" Error with Attachments in Webmail (Horde)
The RSET error some of our customers are experiencing when attempting to send an email with an attachment larger than 1Mb is related to a programming issue between the hosting control panel software we use (cPanel) and one of the mail programs (Horde webmail).
There is a team from both providers working on a solution. In the meantime, we recommend using the RoundCube version of webmail. This works with no issues.
To change from Horde to RoundCube, follow the steps below.
1) Log into your webmail as usual
2) Click the little drop down arrow in the top right hand corner next to your email address.
3) In the menu that appears, select RoundCube instead of Horde
Once the developers have a solution in place, we will let you know if you wish to switch back to Horde at that time.
