What is the spamscore of the emails? You could start with making your spam policy more strict. The tutorial you are linking to blocks all email from a tld (so .com, .net, etc), I wouldn't suggest doing that. You can block a specific domain under Email -> Blacklist -> Add blacklist record -> User: yourdomain.com, Email: @example.com
From the last log it looks like you are sending mails to mail.ru and they have temporarily blocked your server. I am not sure that blocking the domain will solve the source of the problem
I try this under ispconfig menu Mail :Content filter Postfix Header and Body Checks Yes ns3xxxxx.ip-94-23-7.eu /<.+?@.+?.ru>/ REJECT ==> seems do not wok Menu Mail / Postfix / Blask List Email Blacklist Yes nsxxxxxxx.ip-94-23-7.eu mail.ru Recipient Do not work ==> This ch**t create some pb on the server, Kill mysql server or my web server
You should stop postfix. At the moment your server is sending so much spam, that it blocks other services. Furthermore your IP will loose all reputation and you will not be able to send mails anymore in the near future. Stop sending mails Set in your /etc/postfix/main.cf Code: defer_transports = hold default_transport = hold Then "postfix reload". Now all mails should go to queue (mailq) and not being sent. There you can delete (postsuper -d ID) or release (postsuper -r ID) them Find the source of sending mails. Probably some php code (wordpress plugin, etc..) Remove problem, revert postfix conf change, release good mail and hope your reputation will recover
I add this at the end of main.cf message_size_limit = 0 ################################### smtp_header_checks = regexp:/etc/postfix/smtp_header_checks defer_transports = hold default_transport = hold ==> do not work, ===> the mail is always sent via an email but does not exist [email protected] on server currently I checked in all the database (in past it has been created, no pb) That's the problem I stop potsfix ==> mail stop Code: eb 24 22:24:47 xxxxxxx postfix/qmgr[10970]: 777C51D5109A: from=<[email protected]>, size=12528, nrcpt=1 (queue active) Feb 24 22:24:47 xxxxxxx postfix/qmgr[10970]: CDA731D40A30: from=<[email protected]>, size=12410, nrcpt=1 (queue active) Feb 24 22:24:47 xxxxxxx postfix/qmgr[10970]: EB2421D484C5: from=<[email protected]>, size=12522, nrcpt=1 (queue active) Feb 24 22:24:47 xxxxxxx postfix/qmgr[10970]: 061BD1D4A41C: from=<[email protected]>, size=12540, nrcpt=1 (queue active) Feb 24 22:24:47 xxxxxxx postfix/qmgr[10970]: BB18E1D54262: from=<[email protected]>, size=12522, nrcpt=1 (queue active) Feb 24 22:24:47 xxxxxxx postfix/qmgr[10970]: DE3901D5B8BA: from=<[email protected]>, size=12391, nrcpt=1 (queue active) Feb 24 22:24:47 xxxxxxx postfix/error[11056]: 8366D1D4E51D: to=<[email protected]>, relay=none, delay=25616, delays=25610/5.7/0/0.17, dsn=4.3.2, status=deferred (deferred transport) Feb 24 22:24:47 xxxxxxx postfix/error[11040]: 1153A1D58E4A: to=<[email protected]>, relay=none, delay=9729, delays=9723/5.7/0/0.17, dsn=4.3.2, status=deferred (deferred transport) Feb 24 22:24:47 xxxxxxx postfix/error[11038]: C52A01D4BB55: to=<[email protected]>, relay=none, delay=33781, delays=33775/5.7/0/0.17, dsn=4.3.2, status=deferred (deferred transport) Feb 24 22:24:47 xxxxxxx postfix/error[11027]: 5B7591D47768: to=<[email protected]>, relay=none, delay=38058, delays=38052/5.7/0/0.17, dsn=4.3.2, status=deferred (deferred transport) Feb 24 22:24:47 xxxxxxx postfix/error[11059]: 4B4FC1D5FD72: to=<[email protected]>, relay=none, delay=420, delays=414/5.7/0/0.17, dsn=4.3.2, status=deferred (deferred transport) Feb 24 22:24:47 xxxxxxx postfix/error[11057]: 036C81D477A4: to=<[email protected]>, relay=none, delay=38055, delays=38049/5.7/0/0.17, dsn=4.3.2, status=deferred (deferred transport) Feb 24 22:24:47 xxxxxxx postfix/error[11001]: 163FB1D4F518: to=<[email protected]>, relay=none, delay=24707, delays=24701/5.7/0/0.17, dsn=4.3.2, status=deferred (deferred tra
