E-Mail / Weird, no mail server but forward works

« on: August 29, 2022, 08:04:05 PM »

So I have a bad boy client......my brother....ugg.   He got me in trouble a few years ago when he started spamming people.  So I kicked him off my server.   Now fast forward 2 years and I decided to give him a another chance.  But this time, I set his email accounts to 0 by creating a custom package just for him.  Great, that worked.   But he was able to set up a forwarder from his domain email.  Uggg.......

So he can advertise his personal email on his websites and other nefarious locations.  Then his emails will be forwarded to his Gmail account.

I think this is a bad situation.

E-Mail / postfix main.cf different on 2 Stream servers

« on: January 03, 2022, 09:52:14 PM »

OK, postfix on my stream server has been a total nightmare for the past 3 weeks.

I have stream8 server.   Nothing but trouble.

So I spun up another stream8 server to compare postfix files.  And they are totally different.  Both running postfix 3.4.8 and both have major differences.

So what do I do at this point?  I think all of my complaints has caused developers to investigate and as a result, they have made significant changes to the main.cf file.

I need to know how to proceed with my original stream8 server which is only 3 weeks old.  My new stream8 server is a few days old.

E-Mail / smtpauth not working for me.

« on: December 07, 2021, 12:23:19 AM »

I have a problem using smtpauth from my ecommerce platform.

If I use mail.lakeservers.com I get an error:

warning: TLS library problem: error:14094415:SSL routines:ssl3_read_bytes:sslv3 alert certificate expired:ssl/record/rec_layer_s3.c:1544:SSL alert number 45:

If I use the server server.companiondriver.com  I get no error.  What is different about the two certs?

CSF Firewall / syslog group name

« on: December 04, 2021, 12:08:17 PM »

I was looking at csf config.  They recommend option 3 for restrict syslog.  this requires creation of user group.  My question is what user name for group.   Is it arbitrary or is it a system user like root?
