username: aimsul
server: stevie
domain: aimsul.org (addon domain sullivan.gs )
I am unable to send email from either the account set up on my main domain or from the one on my addon domain. I can receive email just fine, and I can sign into webmail and that also works, however sending email from another client does not work. I have successfully sent and received email before using Thunderbird and also the Mac mail application. I did not change any settings but today I could not send email (except, as I said, through webmail). In a fit of pique I deleted Thunderbird and reinstalled and recreated my accounts using the configuration information supplied in cPanel, to no avail. The Mac mail app also won't send. I have now tried the same settings on a different computer using Pegasus mail and I get the same thing-- receiving is fine, but no sending.
Pegasus tells me: Connection timeout (no response from host). Socket timeout.
Thunderbird tells me: Sending of message failed. The message could not be sent because the connection to SMTP server mail.aimsul.org timed out. Try again or contact your network administrator.
Evolution says: Welcome response error: connection reset by peer.
I also tried various permutations of aimsul.org (/sullivan.gs) and stevie.heliohost.org with and without SSL to see if that was the issue, but basically there is no sending going on at all, except from webmail.
One more thing, I noticed that between my starting typing this message and now, all my subdomains and addon domains have disappeared.
I did have:
sullivan.gs (add on domain)
work.aimsul.org (subdomain)
aimsul.co.cc (parked)
And they are now all gone in cPanel. (Trying to access them is alternately getting me a 500 error/actually connecting; I don't know what to make of all this any more.)
Thank you for your help.
