E-mail Access: "You have received an invalid certificate"

[CJECulver]

While I can receive e-mail through my Bluehost accounts, I cannot send:

"You have received an invalid certificate. Please contact the server administrator or email correspondent and give them the following information:

Your certificate contains the same serial number as another certificate issued by the certificate authority. Please get a new certificate containing a unique serial number."

What's up?

It sounds like you're try to use SSL for your email, and that's not supported on BH. You need to be using ports 110 for incoming and either 25 or 26 for outgoing, with SSL turned off.

I have this happening as well when I try to send an email using the SMTP of a parked domain.
So lets say I have the main domain as www.mydomain.com and I have installed a parked domain called www.otherdomain.com.
While I can establish accounts and receive POP email via mail.otherdomain.com I obviously cannot send email using mail.otherdomain.com as SMTP server.
An attempt to do so is "rewarded" with the error message mentioned above.

I only can use the SMTP server of the main domain mail.mydomain.com.

Not quite happy with that but never dug deeper if it's a bug, a configuration question, or simply not possible by design.

Hi,

My mail was working fine (incoming and outgoing) through Thunderbird until about a week ago when I started getting this exact same error message. I continued to receive mail but couldn't send anything.

Since then I've tried to change the outgoing port to 26 as suggested in these instructions (http://helpdesk.bluehost.com/kb/index.php?x=&mod_id=2&id=161). No luck. My attempts have worsened matters so that now I can't access the accounts at all. This is the new error:

"Mail server is not an IMAP4 mail server."

Does anyone know what sort of mistake on my part would prompt something like that? :(

Very much appreciated!

Edit: The plot thickens...

I can access my e-mail and simultaneously disarm the IMAP4 messages so long as (what I think is) the incoming port is set to 143. It doesn't work with 110. :( Setting the port as 110, 25, 26, or 14 (the default according to Thunderbird) all lead to the IMAP4 message. I'm curious as to why...

I can send and receive mail again in Thunderbird with the following settings:

Server Type: IMAP Mail Server
Sever Name: mail.MYDOMAIN.net
Port: 143
User Name: MYNAME+MYDOMAIN.net
Use secure connection: Never
(Use secure authentication unchecked)

SMTP (Outgoing) Server Name: mail.MYDOMAIN.net
Port: 26
(Use name and password checked)
User Name: MYNAME+MYDOMAIN.net
Use secure connection: No

Is it OK to have things like "Use secure connection" unchecked? These are the other options aside from "Never" and "No":
TLS, if available
TLS
SSL

I get the same error each time I connect to the mail server:
"Mail server <mail server name> is not an IMAP4 mail server"
once for each account.
The above post is the closest I've see to this. Does anyone know why one gets this? I've searched for a post on this and this is the closest I've found.
