Unable to send mail from within Webmail
I have a few customers complaining that they can not send mail from within there webmail clients. We offer three of the clients, Horde, Squirrelmail and Roundcube.
This does not seem to be effecting everybody, because I have a few of my own sites on this server and I have no problems sending webmail from with Horde or Squirrelmail.
cPanel 11.24.4-C33795 - WHM 11.24.2 - X 3.9
REDHAT Enterprise 5.3 i686 on standard
We are using the CSF/LFD plugin as well as mod_security2
Would like some help on fixing the problem if possible.
I did not check all of my own sites...bellow is a error I receive when attempting to send an email from within Horde. I do not have any other email address setup for this account, just using the main account username by default.
This is exactly what I'm getting on customer accountants also.
There was an error sending your message: Failed to add recipient: my send to email address here [SMTP: Invalid response code received from server (code: 550, response: Verification failed for <email@example.com> No Such User Here Sender verify failed)]
Can't send emails from Horde
Hi there, I am unable to reply to emails that were received using Horde. I always get the following error message:
There was an error sending your message: Failed to add recipient: person_I_am_replying_to@blahblahblah.co.uk [SMTP: Invalid response code received from server (code: 550, response: Verification failed for <firstname.lastname@example.org> No Such User Here Sender verify failed)]
Any suggestions very welcome.
