Do you not have a better method of reporting program defects than sending a suggestion through from the support page ? I sent through a report at the beginning of the month regarding the search indexing service crashing and have, to date, received no feedback whatsoever. There is also no obvious way...

Been around for a while:

Look in the MailEnable installation folder at Config/<postoffice>/Mailboxes. The sys files in there contain a field with an email address that you could probably use.

The remote server could be greylisting or have a receive limit. You would need to contact whoever runs the remote server as there is nothing ME can do about that.

Do you have SMTP retries set ? That would get around greylisting by retrying after a temporary failure.

Send email via SMTP on port 25

Your DNS entry has a SPF record but you don't seem to be checking. SPF would fail that email that is supposedly coming from you as the email server it came from would not be authorised to send for your domain. Check SMTP Properties under Sender Policy Framework to enable, and then set a filter to qu...

Our largest list is only around 3000 emails, and we use Enterprise edition, so I'm not sure how it would be in Standard edition.

Currently no "specific time" mailing, they go out when received so you would have to handle the timing issue externally.

Generally the SMTP activity/debug log files will have all the information about connections successful or otherwise.

This is what their own SPF record shows:

include:_netblocks1.mailhostbox.com include:_netblocks2.mailhostbox.com include:_netblocks3.mailhostbox.com

Try adding those to your SPF record.

If you are already getting the MailEnable denied message, which was not mentioned in your original post, then the connection is not being blocked on their side so you need to find the log file that will say why the block was being made.

Try, from their office, telnet <your ip> 80 (assuming you are running a web server) to check if the block is actually from ME or from some firewall setting on their side.

(Note that the telnet connection is not supposed to actually work, you should just get a HTTP 400 response)

Those IP addresses all belong to webhostbox.net who is obviously your domain host. You will need to include their spf record into your own spf record in order to cover all possible outgoing mx ip addresses. Just ask them for the entry you need to add to your spf record to include their mx ip address...

In Webmail select Options from the top bar then in General > Account Settings > Contact details use Add/Edit image
