Коллеги, помогите пожалуйста с проблемой. Есть доменная почта на Яндексе, условно обозначим именем yagroup.ru С таким же именем yagroup.ru внутренний домен. Подняли почтовый сервер Debian 11, postfix 3.5.18 на втором уровне домена с именем gkgroup.ru Ситуация следующая, при отправке на внешнюю почту яндекса, с таким же доменным именем как и внутренний домен (yagroup.ru ) сервер стучится на кд, в итоге получаю Connection refused, status=deferred и висящее в очереди письмо. Во всех остальных случаях всё прекрасно работает… [spoiler=mail.log] May 23 13:17:22 mail postfix/submission/smtpd[3036]: connect from localhost[127.0.0.1] May 23 13:17:22 mail postfix/submission/smtpd[3036]: Anonymous TLS connection established from localhost[127.0.0.1]: TLSv1.3 with cipher TLS_AES_256_GCM_SHA384 (256/256 bits) key-exchange X25519 server-signa> May 23 13:17:22 mail postfix/submission/smtpd[3036]: 4QQTH65NNZz3cq6H: client=localhost[127.0.0.1], sasl_method=LOGIN, sasl_username=petrov@gkgroup.ru May 23 13:17:22 mail postfix/cleanup[3052]: 4QQTH65NNZz3cq6H: message-id=<30b74af0cab6e948c7a51a2d1b307d9e@gkgroup.ru> May 23 13:17:22 mail postfix/qmgr[2057]: 4QQTH65NNZz3cq6H: from=<petrov@gkgroup.ru>, size=659, nrcpt=1 (queue active) May 23 13:17:22 mail roundcube: <tl39kq6a> User petrov@gkgroup.ru [192.168.0.50]; Message <30b74af0cab6e948c7a51a2d1b307d9e@gkgroup.ru> for petrov@yagroup.ru; 250: 2.0.0 Ok: queued as 4QQTH65NNZz3cq6H May 23 13:17:22 mail postfix/submission/smtpd[3036]: disconnect from localhost[127.0.0.1] ehlo=2 starttls=1 auth=1 mail=1 rcpt=1 data=1 quit=1 commands=8 May 23 13:17:23 mail postfix/10025/smtpd[3063]: connect from localhost[127.0.0.1] May 23 13:17:23 mail postfix/10025/smtpd[3063]: 4QQTH72QbLz3cqfS: client=localhost[127.0.0.1] May 23 13:17:23 mail postfix/cleanup[3052]: 4QQTH72QbLz3cqfS: message-id=<30b74af0cab6e948c7a51a2d1b307d9e@gkgroup.ru> May 23 13:17:23 mail postfix/10025/smtpd[3063]: disconnect from localhost[127.0.0.1] ehlo=1 mail=1 rcpt=1 data=1 quit=1 commands=5 May 23 13:17:23 mail postfix/qmgr[2057]: 4QQTH72QbLz3cqfS: from=<petrov@gkgroup.ru>, size=1954, nrcpt=1 (queue active) May 23 13:17:23 mail amavis[2179]: (02179-01) Passed CLEAN {RelayedInternal}, ORIGINATING/MYNETS LOCAL [127.0.0.1]:49942 ESMTP/ESMTP <petrov@gkgroup.ru> -> <petrov@yagroup.ru>, (), Queue-ID: 4QQTH65NNZz3cq6H,> May 23 13:17:23 mail postfix/amavis/smtp[3057]: 4QQTH65NNZz3cq6H: to=<petrov@yagroup.ru>, relay=127.0.0.1[127.0.0.1]:10026, delay=0.76, delays=0.2/0.03/0.02/0.51, dsn=2.0.0, status=sent (250 2.0.0 from MTA> May 23 13:17:23 mail postfix/smtp[3064]: connect to yagroup.ru[192.168.0.2]:25: Connection refused May 23 13:17:23 mail postfix/smtp[3064]: connect to yagroup.ru[192.168.0.3]:25: Connection refused May 23 13:17:23 mail postfix/smtp[3064]: connect to yagroup.ru[192.168.0.4]:25: Connection refused May 23 13:17:23 mail postfix/qmgr[2057]: 4QQTH65NNZz3cq6H: removed May 23 13:17:23 mail postfix/smtp[3064]: 4QQTH72QbLz3cqfS: to=<petrov@yagroup.ru>, relay=none, delay=0.05, delays=0.01/0.03/0/0, dsn=4.4.1, status=deferred (connect to yagroup.ru[192.168.0.4]:25: Connect> May 23 13:18:33 mail postfix/postsuper[3147]: Deleted: 1 message [/spoiler] [spoiler=dig gkgroup.ru MX] ; <<>> DiG 9.16.37-Debian <<>> gkgroup.ru MX ;; global options: +cmd ;; Got answer: ;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 18341 ;; flags: qr aa rd ra; QUERY: 1, ANSWER: 0, AUTHORITY: 1, ADDITIONAL: 1 ;; OPT PSEUDOSECTION: ; EDNS: version: 0, flags:; udp: 4000 ;; QUESTION SECTION: ;gkgroup.ru.
