Troubleshooting Problems when Sending Email

I started getting numerous messages like this one this afternoon:

This message was created automatically by mail delivery software.A message that you sent could not be delivered to one or more of itsrecipients. This is a temporary error. The following address(es) deferred:  {email address}

    Domain {my website address} has exceeded the max emails per hour (300/250 (120%)) allowed.  Message will be reattempted later

   I thought this must mean a have a virus on my computer that is spoofing my email address but after a very long conversation with my antivirus provider, I was told this is more likely to be a problem coming from my email provider.  I have since changed my email password, but I do not know what else to do.

We are seeing this error a lot lately. We do not send mass emails, nor are there many people using this domain. How do we resolve it?

I am unable to send emails to certain accounts but I am able to send to others.

FOr one I am getting the error message:

SMTP error from remote mail server after end of data:

host mx.bellaliant.net

550 Message rejected

While the other just automatically got sent to my outbox

Hello,

I am unable to seccessfully send email to other accounts.  I am using outlook 2013 and I do receive the "test" message in my own inbox.  Port 25 appears to be blocked as I do not receive any sort of response.  I have tried port 587 with auth checked and no SSL,  I receive "test" msg in my own inbox but any sent email are never received.  When checking telnet  on port 587 I receive the response from ehub36.webhostinghub.com.  If I try to set up my outgoing mail server as secure36.webhostinghub.com and use port 465 with ssl and smtp auth I still receive my own test message but again, no one receives my actual email.

Please advise went I am missing/doing wrong or can you please advise a solution.

Very much looking forward to a solution.

Regards,Eric

I am unable to successfully send emails.  They show as sent but the recipient never receives them.  I send emails to another one of my accounts and I am able to confirm non-receipt.  My port 25 appears blocked so I have tried using port 587, auth ticked, no ssl and no result.  I have checked port 587 with telnet and the response is "220-ehub36.webhostinghub.com ..." and so I have also tried changing my outgoing mail server to "secure36.mydomain..." port 465 with ssl and auth tick for smtp server and still no luck.

I have tried this on three computers, two of which are new DELL laptops.  All running Outlook 2013. No AV on the new laptops and the other PC is able to send fine it's other email accounts.  When I use port 587 or 465 as described above I do receive the Outlook "test message" to myself but no other emails are successfully received.

Your assistance is appreciated.

I've been getting errors stating the recipients do not exist and it is a permanent error. On their end, they also receive the same messages trying to email me.

This does not happen to other recipients in a different domain.

Here is a copy of  the message: (please help!)

receiving this error when try to send to this email only. Can you tell me where the problem is? I don't see any issues with the email?:

There are non-ASCII characters in the local part of the recipient address ??drq@healthylifestylestampabay.com. This is not yet supported. Please change this address and try again.

I have a desktop PC, as well as an iPhone 7 and an iPad Air all configured accurately for IMAP for quite some time as I’ve never had an email issue until now.  This past week, for some reason, I ceased to be able to send emails on either of my IOS devices.  Incoming email arrives just find.  Email on my desktop continues to work for both sending and receiving through Outlook in Office 365.  I read through the two scenarios of what could cause sending issues to occur and neither seemed to apply to my IOS devices.  When I try to send on either device, I immediately receive an error msg:  Cannot Send Mail. A copy has been placed in your Outbox.  The recipient <email address> was rejected by the server.  I’ve tried to send to several different email addresses to no avail.  I checked my IOS devices’ settings to your protocol for an IMAP account with SSL and they all appear to be accurate.  On Apple’s support site, it said that when nothing else works, try deleting the account and reinstall.  I did that, but no change in the outcome.  I then called Apple support for assistance and they said the problem has to be on my email provider’s end.  The settings I’ve used for my IOS devices included selecting IMAP, User Name is my email address.  Host Name for incoming mail server is secure57.webhostinghub.com. Outgoing Mail server is SMTP with secure57.webhostinghub.com.  “Use SSL” is selected.  Authentication selected is password which I double-checked to be accurate through my desktop and Webmail.  Server Port is 993 and S/MIME is not selected.  Any ideas what might be wrong?  Thank you so much for your help.  Mike G.

Hi there,

For the last three weeks, my email server is playing out - sometimes it works, but most of the time the outgoing emails bounce, and occasionally incoming emails don't make it.  I use the mail program on my MAC, and until this happened I had no problems.

Any ideas?  Here below a typical bounce message:
