    Issue Mail to some addresses not sent - Postfix - Connection refused

    Thank you, StormFiber. Agreed. But that option may not be always possible. For example, a certain IP address leads to "Connection Refused". I cannot contact the sender neither via email nor phone, to ask them to inquire. I am left then with looking up the IP address source, only to find...

    Issue Mail to some addresses not sent - Postfix - Connection refused

    Thank you Peter. If the recipient server didn't want to talk to the sending server, the sender would usually receive a "rejection" message of some sort. But your suggestion is still a possibility.

    Issue Mail to some addresses not sent - Postfix - Connection refused

    Thank you for the feedback. Port 25 is open on my server and I can connect to the server from my local computer. I checked our server (domain) and it is 100% not blacklisted. I used this link:- http://multirbl.valli.org/lookup/ It's one of those things that bug ! One tried every possible...

    Issue Mail to some addresses not sent - Postfix - Connection refused

    Not sure about their end really. It's not always possible to find this out. But If I telnet their IP address, I get the same result .. (Connection refused) Is there a simple test to find out from my end whether their port 25 is open? If not, is there a way round it?

    Issue Mail to some addresses not sent - Postfix - Connection refused

    Hello, I am having this strange problem. Emails can be sent to some addresses but not others. OS: CentOS Linux 7.6.1810 (Core) Product: Plesk Onyx 17.8.11 Update #95 /var/log/maillog says this:- Mar 21 17:13:54 server416 postfix/pipe[1981]: BD72B21DB1: to=<user@domain.com>...

    Resolved Changing Hostname +Maillog +Good Practice?

    Monty, Thanks a lot for your response. I can now exclude change of hostname as a cause, taking into consideration the 'checks' you mentioned:- There are a few things however that you should check: Make sure the new hostname is a FQDN that can be resolved Make sure the entry in...

    Resolved Changing Hostname +Maillog +Good Practice?

    Hi, This is a quest for knowledge and would greatly appreciate advice from experienced Pleskians. In a previous post, I encountered the problem of "empty maillog". While working on a new rebuild, I remembered that the problem started after changing hostname via Plesk like this:- Tools &...

    Hi Monty, Sorry about the delay, it has been hectic trying all sorts. "Plesk repair all" didn't find errors (STRANGE!) Plesk support must be done through our slow_uncooperative webhost. Their advice is that it might be quicker to re-build the server than get a response from Plesk. It would...

    Resolved "message content rejected" + outbound.protection.outlook.com + google.com

    Monty, I am grateful for your responses. I will follow the 5 steps as per your suggestion. The server has the correct time. I am now more concerned about maillog being empty than the main issue because it is needed to check things. The file /etc/rsyslog.conf contains the lines: # Log all...

    Sorry to bother you with this extra point: I have just noticed that /var/log/maillog is empty. Have tried to restart server, to no avail. I restarted syslog + postfix services: service syslog restart service postfix restart Then maillog is filled with entries dated June 28 ! Nothing is...

    Thanks. I will do pastebin shortly and let you know when it's done (never used it before). The file main.cf is too large for plesk to accept (more than 10000 characters). Have tried to upload it but it won't accept extensions cf + txt or even withput extension. So I removed all the commented...

    Issue No such user in mail authorization database

    Unfortunately it hasn't worked! I am thinking of deleting all email accounts and re-create them again. Problem is that even when I create a new email, sending works but it cannot receive!
