  • He needs to use a mta that supports arc sealing and setup his Google workspace to accept the arc from his server. Pretty sure Google also supports connectors for email so he could even just have Google accept all emails from his ip. I suspect he is cheaping out and doesn’t want to pay Google for a business grade service.

    I don’t care what he did in the past, it is obvious he is not an up-to-date email admin. Using free consumer accounts as your primary email, is not a defendable position for anyone other than the self employed.







  • Ok so this one is someone trying to move to “the cloud.”

    They had a database they used. It was on a server in the office. We were tasked to clone the db server to a hosted VM. Due to order of creation this got put on a new host without anything yet on it.

    They needed a site to site VPN to keep privacy, that was all fine. However after the clone and during testing, their guy there said that this one part was really slow. We take a look and everything is good with performance of the server and of the VPN. I have to pop on to take a look.

    It was in an office app and written in VB. (I forgot which one.) It was indeed slower on the hosted server. So I took a look at the function (he got it up for me) and I could instantly tell the issue.

    This part was a lookup page that searched for you input. The function retrieved the entire table, then filtered the results in the client. I explained that transferring the whole table over the internet would be slower than on the local lan.

    This guy said he originally wrote this, but “forgot VB.”

    In the end they decided not to update the app or keep the server in the office, but instead they rented some VDIs in the same data centre as the db.





  • Probably unrelated, domain spoofing is common, but miss-configured mail servers will accept those emails and process auto replies. They can also abuse input forms to try and send out emails, but that typically does not have much control over content.

    If you are getting more emails than you can deal with, than can be used to try and mask other emails by burying them in a large email volume. In that case you should be looking for emails from important accounts you do own (eg banking.)
