SSL_accept error from...

[Ralf Hildebrandt <Ralf.Hildebrandt@xxxxxxxxxx>]

I found quite some SSL_accept errors in my maillog:

Oct 18 11:58:42 mail postfix/smtpd[11534]: SSL_accept error from medusa.odn.de[212.34.160.34]: -1
Oct 18 12:27:00 mail postfix/smtpd[16425]: SSL_accept error from whirlwind.med.nyu.edu[128.122.2.137]: -1
Oct 18 12:51:47 mail postfix/smtpd[18901]: SSL_accept error from ns.turtle-trader.com[66.117.46.150]: -1
Oct 18 12:59:42 mail postfix/smtpd[20509]: SSL_accept error from medusa.odn.de[212.34.160.34]: -1
Oct 18 13:27:12 mail postfix/smtpd[24407]: SSL_accept error from node-cffb9331.sfo.onnet.us.uu.net[207.251.147.49]: -1
Oct 18 13:58:13 mail postfix/smtpd[28559]: SSL_accept error from mail.my-mail.ch[62.2.245.28]: 0
Oct 18 14:00:45 mail postfix/smtpd[29348]: SSL_accept error from medusa.odn.de[212.34.160.34]: -1

a) What do they mean?
b) Why sometimes -1 and sometimes 0?
c) Does this affect the ability to receive mail from e.g. medusa.odn.de?
   I guess it does:

Oct 18 14:00:44 mail postfix/smtpd[29348]: connect from medusa.odn.de[212.34.160.34]
Oct 18 14:00:44 mail postfix/smtpd[29348]: setting up TLS connection from medusa.odn.de[212.34.160.34]
Oct 18 14:00:45 mail postfix/smtpd[29348]: SSL_accept error from medusa.odn.de[212.34.160.34]: -1
Oct 18 14:00:45 mail postfix/smtpd[29348]: disconnect from medusa.odn.de[212.34.160.34]

Why you can't find your system administrators:
they've snapped, started muttering about "this damned post office", and left for the nearest gun store
