    Hey All,
    I've been running in circles because of a particular step which i have successfully reproduced every time and when undone, things resumed working. The step in question is
    A little bit of background, I'm running a freshly spun Deb Stretch on DO droplet. After adding the limit increase file, MariaDB refuses to start. Upon deleting the file, MYSQL can be started. I copied and pasted the texts and configs and left almost nothing to manual typing and yet this happens.
    Any ideas why? Perhaps Maria updated something which prevents the limit file from being added?

    Which errors do you get in syslog or mysql log file when you try to start mysql?

    Hi All,
    Sorry for the long pause. I was trying and going out of my mind. Everything i compiled, downloaded, installed all had problems. As it is now, i've even refreshed my OS and all the tools i use i.e. winscp, putty etc. Now it seems ISP config can be installed. But i'm facing a totally different issue now. The mailserver does not seem to be functioning properly. Should i open a new thread and close this one?

    This is from mxtoolbox
    I'm using rainloop webmail, i've also done the proper setup in the /?admin section of rainloop. Thank you for your responses Till and ztk!

    make sure your mailname matches IP RDNS entry, MX entry points to correct IP, IP can be looked up and is reachable.
    Check if your port 25 is blocked for in/out bound ( probably the case? )
    You mentioned you reinstalled? Have you removed the comments for submission ports in postfix master config? Is port 587 blocked?

    Hi All,
    1. I have no idea where to check for the rdns whether it matches. I use cloudflare. But MXtoolbox showed it resolves to the correct ip.
    2. According to, my port 25 and 587 is open.
    3. I have uncommented both lines in the postfix master config.
    Any ideas where i went wrong?

    yougetsignal checks incoming ports but not outgoing port.
    Can you netcat/telnet the xxx. IP on smtp port?

    Connection abort after 15 seconds looks like a timeout value and no communication issue to me.

    reverse DNS is the hostname you see when looking up an IP - using $traceroute ip or $host ip for example

    Hi All,
    Ztk, I putty-ed the ip on port 25 and nothing comes up and neither does it timeout either. what do you think indicates?

    nothing comes up... but it should - if you used the telnet feature. I don't remember well how long it takes or if it does give a message at all, long time ago I used putty.

    How does your file look like - and is there anything interesting in the while restarting postfix?
