Mail::Pop3Client messing up PGP email messages

Popcorn Dave has asked for the wisdom of the Perl Monks concerning the following question:

Fellow monks,

I'm working on a project where I send an encoded web based form as an e-mail and want to retrieve it via a web based client on the other end.

The encryption is working just fine on both encoding and decoding - that is if I look at the message in my e-mail client. However when I try getting the message using Mail::POP3Client, it appears to be losing some line breaks along the way as shown by the PGP snippets below.

What I'm getting

-----BEGIN PGP MESSAGE----- Version: Crypt::OpenPGP 1.03 hQIOA3d7Jqbzm
+ZZ1EAgAggmlYb1TnK+xTIw4jmxEfIn78S+6tNccDK3576FRJxKZ
--clipped--
KoaBzlX71FsQUXLNPPjy9OyG/ikB6U4SZJ0LrRetb+KlAhKdvo8ygZKajilHsEm8 Z9lEE
+16m =3D1k9I -----END PGP MESSAGE-----

What it should be:

-----BEGIN PGP MESSAGE-----
Version: Crypt::OpenPGP 1.03

hQIOA3d7JqbzmZZ1EAgAsGxJsR3nzBWKi9JDUpMGhRoCnPTPPHp/61nMKnsL8EWI
--clipped--
BeX+Hm9fh/UAeeHPClTq2JuDY1EEqg==
=YcK/
-----END PGP MESSAGE-----

As you can see, the -----BEGIN and the Version should be on seperate lines ( as they show up in my e-mail client ) but they aren't.

I keep getting error messages of a bad checksum, which I am thinking is directly related to the message formatting being messed up. Can someone either reccomend how to solve the problem at hand or is there a different module I should be looking at for retrieving e-mail?

Try Net::POP3 for retrieving your messages. It plays well with MIME-tools. Igor 'izut' Sutton your code, your rules.	[reply]

Thanks for the suggestion! That's retreving the e-mail the way it should be formatted. However... Upon further investigation of my problems, in the encrypted text I'm retrieving, the last 3 = are replaced with =3D, thereby messing up the CRC of the encrypted text. GPG throws a CRC error when I try to decode it manually. However, like I said before, when I retrieve said e-mails in Thunderbird, the =3D is just =. Any ideas on what's causing this mix up? It doesn't seem to be the encryption as that's coming through just fine. Thanks!

That sounds like maybe the message is PGP-signed, then MIME-encoded. If that's the case, to check it you'll have to MIME-decode it (which will change the `=3D` to just `=`) then check the signature. -- sgifford's Web page	[reply] [d/l] [select]

Without seeing code it is hard to guess, but some options are UTF8 issues, *nix/Win32 newlines, and some other encoding problems.	[reply]

That was my original thought too, but I think sgifford may have hit the nail on the head with the MIME decoding idea. Useless trivia: In the 2004 Las Vegas phone book there are approximately 28 pages of ads for massage, but almost 200 for lawyers.	[reply]
