  • I’m not sure why people are trying convince me to change my mind on something.

    I have seen it in my logs with my own eyes. I wish I could be left alone without having to bother looking into it.

    Whatever the reason is. Someone is crawling through dictionaries of address. It is slow but steady. It started with abuse@ and other generic addresses and then started trying names. I blocked the sending SMTP server once I realized what was going-on.

    What am I suppose to do? Ignore it and just triage in inbox?



  • Does it?

    Do you think spammer will just stop at the first address and then call it a day?

    In my experience there is no such thing as a “catch all” domain address. The second your domain leaks then many spammer will just go into a frenzy and try hundreds or thousands of mail aliases.

    Especially since they can’t really spam Gmail as easily (since early 2024) they will even more aggressively spam any other domain.








  • Not OP but everytime I used the verbose output of ssh it didn’t help me one bit. Even adding outrageous verbosity I was still quite confused on what step failed and which didn’t.

    I’m probably just bad at understanding SSH but i don’t know it seems like ssh workflow includes many trial and error until it finds a way to connect.

    Imo the verbose output of SSH is often not very helpful if you don’t know very well ssh in the first place. Obviously it is still worth a shot and a good advice but don’t expect ssh to clearly state what is going on :)

    If you do self host I suggest reading carefully the Gmail guidelines for mails. They are the leaders in the field and they dictate the level of security required.

    DNS forward and reverse, DKIM, SPF, DMARC, ARC, DANE, bounce signature etc. Email is indeed a very complicated thing to host. I work on emails system all day and and I wouldn’t host my own mail.

    Even worse I’m hoping email disappear and another technology takes it place. Emails are unreliable and outdated, they need to go.




  • Good job !

    I highly recommend trying out the various online regex editor.

    These WISIWIG kind of editors are great because you immediately see what the regex is catching and for what reason.

    I took the first one in my search results but try different ones.

    https://regex101.com/

    Also I used GPT to get some regex for some specific strings and it can be helpful to get a quickstart at building a specific regex.

    In that case I was building a regex for a specific log from postfix.

    PS: just make sure to select the correct flavor of regex you are using in these online tools.

    Edit: Also one of my favorite YT channels has pretty cool videos on RegEx : https://youtu.be/6gddK-cOxYc
