Postfix简介： 在IBM的GPL协议下开发的MTA（邮件传输代理）软件，Postfix更快更容易管理，更安全，同时与sendmail保持兼容。 官网地址：http://www.postfix.org/ 邮件服务器发信原理图： postfix构建组成图： 要点： Postfix mail queue（Postfix队列）: 1 maildrop queue maildrop queue 是通过Postfix sendmail 命令发送但是还未被Postfix pickup 服务加到postfix 主队列的邮件所处的队列 2 hold queue smtpd access 策略或者是cleanup的检查可以将部分邮件长时间的放置在hold queue队列 3 incoming queue 所有进入postfix队列的邮件都会由cleanup放置到incoming queue里。 4 active queue 准备发送的邮件队列 瓶颈：CPU、I/O 5 deferred queue 一些发送失败的邮件队列 Postfix收件流程图： Postfix基本配置： Postfix的配置项大概有100个，所以这还真是个问题 1、myorigin 参数指明发件人所处的域 2、mydestination 参数指明Postfix接收邮件中收件人所处的域 3、myhostname

Since I did not find solution to the problem description here , I decided to use sysread and syswrite for dialog with smtp server. Below is my test code: sub test { my ($dbh) = @_; my $server = "smtp.mail.ru"; my $ip = $server; $ip = inet_aton($ip); $ip = inet_ntoa($ip); $ip = &ip2long($ip); my $port = 465; my $pid = 0; my $is_ssl = 1; my $answer; my $user = 'my_mail@mail.ru'; my $buff = 8192; if (&choose_proxy($ip, $port, $dbh, $pid)) { if (&connect($ip, $port, $is_ssl, $pid, $server)){ data_read($buff); my $ehlo = "ehlo mydomain.com\n"; data_send($ehlo); data_read($buff); my $auth = "auth

I have written a perl script to send email using the gmail's smtp server: smtp.gmail.com - use Net::SMTP; my $smtp = Net::SMTP->new('smtp.gmail.com', Port=> 587, Timeout => 20, Hello=>'user@gmail.com' ); print $smtp->domain,"\n"; $sender = "user@gmail.com"; $password = "mypassword"; $smtp->auth ( $sender, $password ) or die "could not authenticate\n"; $receiver = "user@gmail.com"; $subject = "my custom subject"; $smtp->mail($sender); $smtp->to($receiver); $smtp->data(); $smtp->datasend("To: <$reciever> \n"); $smtp->datasend("From: <$sender> \n"); $smtp->datasend("Content-Type: text/html \n");

I am attempting to write a powershell script to send email with a few attachments to 30 people. The emails are personalized, so they must be sent individually. The script works just fine without attachments. However, when using attachments, every other instance of Send-MailMessage fails with: Send-MailMessage : Unable to write data to the transport connection: An existing connection was forcibly closed by the remote host. It does not seem to matter how long I wait/pause between sending messages. Even if I wait several minutes, the first instance will always succeed, the next will fail, the
