I wanted to share an issue we've seen multiple reports of this week, where MDaemon customers have started receiving bouncebacks from Google mail servers.
Valid email is being refused due to PTR record failures, and it's happening for all Gmail domains including customer registered domains that are used with Google services.
I recently ran a survey among our partner program members (all IT support companies) to find out which, if any, of the various social channels they use 'frequently', to help us understand how best to keep in touch.
Of the 324 respondents the results were as follows:-
One of the nice things about using a different browser to Internet Explorer, are the hidden functions that you find are added to make them stand out from the crowd.
Google Chrome has long been my favourite browser for many different reasons but it was only recently that I came across a very useful built-in feature that can turn any web page into an application shortcut.
If you're anything like me, you probably don't have enough time in the day to be checking all of the industry blogs you really should if you want to keep properly up to speed.
Ours is a great way to locate news on releases, technical tips and marketing support among other things, but like all the others, it does require checking frequently in order that you don't miss anything.
If you use our email server software, MDaemon Messaging Server, and you've ever called our support team with issues relating to being unable to send emails, you may have noticed that we often perform a spam blacklist check.
To perform these checks we use just one of a range of useful tools over at the mxtoolbox.com website. We've been using this site for several years as in addition to the blacklist checking you can also do things like query a domain's Mail DNS and SPF records, check whether the SMTP port is answering and even obtain an explanation of message header information. An essential tool to add to your favorites if you are a mail administrator!
It's generally accepted that a message size of around 20MB is too large to send via email, and you'll find in lots of cases that mail servers will actually refuse to accept files that are this big.
There are, however, many servers that don't limit the message size, which means if you try and share that high-quality 150MB video of your cat performing Dancing Queen, both your network and the recipient's will work overtime trying to deal with it.
