Bug#346260: exim4: autoreply problem with $reply_address and non-7bit chars

[Andreas Edler]

Package: exim4
Version: 4.50-8
Severity: normal

With the vacation_transport shown below a sender gets an error message
stating:

 Expansion of "${reply_address}" in vacation_transport transport
 contains non-printing character 195

An example from line of a mail on which occurs this error is:

 From: =?iso-8859-1?Q?Florian_Mei=DFner?= <email at address.removed>

Here the configuration snippet:

 vacation_transport:
 driver = autoreply
 from = "${local_part}@${domain}"
 headers = "X-Vacation: Vacation-Autoreply"
 once = /var/spool/exim/db/autoreply
 once_file_size = 8192
 once_repeat = 60m
 subject = (...)
 text = (...)
 to = "${reply_address}"
 user = mail
