доброго времени суток. А подкажите плиз дилетанту от tls смогу ли я использовать для postfix ssl сертификат с пометкой "X509v3 Extended Key Usage: TLS Web Server Authentication, TLS Web Client Authentication" ?по результатам издевательских (над сертификатом) тестов - это не совсем ясно:
пыталась проверить с помощью msmtp - не получается (в логах - no certificate, то есть сертификат не был отослан на сервер, соотв и fingerprint проверка не срабатывает и отказ на relay получаю), а вот при попытке отослать тоже самое через s_client - все шоколадно.. можно ли извратиться так чтобы этот сертификат работал и с обычными smtp клиентом?
Заранее благодарна за любой совет!результаты тестов:
1) неудача с msmtp:

ops, sorted out - просто данный сертификат не совместим с msmtp :) и отлично вписался в IIS smtp virtuatl server (стоит послать инфу в msmtp_users видимо..)
