Bug#823064: libmail-srs-perl: decode address with smashed case returns no decoded address

[Adrian Zaugg]

Package: libmail-srs-perl
Version: 0.31-5
Severity: normal
Tags: upstream

Dear Maintainer,


Decoding an SRS tagged address with all lower case issues an error message and no decoded address. 

The doc at http://www.libsrs2.org/srs/srs.pdf, section 4.1 says: [...] "Consequently the Mail::SRS implementation is not case sensitive." A similar description can be read in the source's comments in SRS.pm.

Hence libmail-srs-perl should decode an address even when the case was smahed.

Example:

ente:/home/adi$ srsc
FORWARD test at original-to.example.tld forwarding-service.tld
SRS0=oOhFyc++V0Szn3mOry/ivIMV=P5=original-to.example.tld=test at forwarding-service.tld

ente:/home/adi$ srsc
REVERSE
srs0=oohfyc++v0szn3mory/ivimv=p5=original-to.example.tld=test at forwarding-service.tld
ERROR: Parse error in
`srs0=oohfyc++v0szn3mory/ivimv=p5=original-to.example.tld=test': SRS:
Case insensitive hash match detected. Someone smashed case in the
local-part. at /usr/share/perl5/Mail/SRS.pm line 421, <GEN86> line 1.

I do not get the decoded address back with a reverse call of a lower
cased SRS address. Without it, it gets difficult to accept such bounce messages in a mail server config.

I would expect the decoded address and maybe a warning, not an error.

The version of libmail-srs-perl is the same in all Debian suites.


Best regards, Adrian.
