Our server seems to be working fine receiving and sending email, but when I've tested with some online SMTP server testers, it always times out.
www.wormly.com
MX Lookup Tool - Check your DNS MX Records online - MxToolbox (diagnostics, smtp test)
On the WHM, Email Deliverability, we have green marks on all.
Both wormly.com and mxtoolbox.com show timeout errors.
Does a normal Exim cpanel server also do this?
I have another mail server running Webmin/Virtualmin and Postfix and it passes both server tests with no problems.
thanks for any guidance.
