Smtp problems while sending to some addresses - error: rcpt not accepted from server
After site migration to another serwer we have problems with sending emails with PHP via SMTP (some customized PHPMailer). We can send emails to most of addresses but some giva as errors like below. Does anaybody has any suggestions whats wrong? Is it SMTP servers issues or script problem? Shouldn't SMTP return some specyfic errors?

Error was in configuration of SMTP server. Server administrator changed some settings (unfortunately he didn't provide exact solution).

I think you're mixing up two issues here. There are two stages in your delivery - from PHPMailer to your mail server, and from your mail server to the recipient's mail server. From your first debug log, I can see that the first stage appears to be working fine - messages are accepted correctly. The second two examples are from your mail server's log, not PHPMailer output, so they are happening in the second stage.
This means that your problem isn't in PHPMailer nor your script, but in your mail server, or its own network connection. Mail servers come and go, and part of the point of the way SMTP works is to cope with errors, outages, and delays, which is why it's a good idea to use a local mail server with PHPMailer (as you're doing) so that it can deal with issues like this without you worrying about it. This does mean that you should keep an eye on your mail server config and its network connection (via the logs), and it's also a good idea to implement a bounce handler, which is not a small task, so that your app can get to hear about delayed errors like these.
The certificate verification failure (I'm not sure why you described that as a success) is likely to be caused by outdated CA certificates; updating your OS packages, or installing a fresh copy of trusted root certificates (read the PHPMailer troubleshooting guide for more on that). The last one just looks like an unreliable mail server - your own mail server should retry the delivery later on - that's what mail servers are for.
Two other minor things: you only need SMTPDebug = 2 for this kind of problem; anything higher is unnecessarily noisy. You're also using an old version of PHPMailer, so upgrade.
