When attempting to send an email via webmail, you may encounter a "Sending Message..." notification for several minutes, and the message will fail to send. Additionally, you might see server errors while navigating through webmail.
Description:
This issue is typically caused by a broken webmail signature. The signature may contain an outdated webmail session ID (highlighted by cpsess##########) in the image URL.
To investigate this, you can inspect the image URL:
- In Firefox, right-click the image and choose View Selection Source.
- In Chrome, right-click the image and select Inspect to view the URL.
Workaround:
The solution is to remove the broken images or links from your webmail signature. In RoundCube, you can edit your signature by following these steps:
- Navigate to Settings > Identities.
- Edit or remove any problematic images or links from your signature.
