If you need to send emails, you could:
a. use Sendgrid or Mailgun or whatever to send emails if they don't block exit IPs from connecting to their SMTP relays
b. Run your own SMTP relay on a $3.5 VPS to forward emails
You could also run an SMTP-to-something else protocol bridge to work around it. I use a fake SMTP server that relays every message it gets over XMPP to work around that problem.

Thanks, Neel and yl had already messaged me privately. I replied to them yesterday. I had already solved the problem, unattended-upgrades and logcheck mails reach me again.
Actually, I should know that we should avoid exit IPs for DNS, mail and other things. I configured nullmailer as usual, then it takes the first IP and interface it finds. I was sending mail as a client through|to my DNS provider's SMTP server 'easydns.com'. They recently started using abusix before smtpauth as well. Only a /27 are exit IP's per server. Now the mail goes out on a completely different subnet and network card.
Well I could have pinged Mark Jeftovic @ easyDNS too, please whitelist _my_ IP for _my_ mailbox. Or sending mail out via the SMTP server from IN-Berlin, like my iRMC (BMC) do.
