Hi Pavlo!

Thanks for sharing!

Sorry it took me so long to respond. Further comments below.

Do you have an example of this?

Perhaps I can add APIs for these offsets w/o the header hack in a future 
version (such as a 3.0 where it is ok to break ABI).

It seems many web servers offer gzip and deflate.

I'll think about this more, but I'm thinking I might add this to GMime.

I've already applied the gmime-filter-gzip patch for the Z_BUF_ERROR on 
EOF. Thanks!


Do you have more info about the Thunderbird workaround and the 
quoted_decode() workaround? (from what I can tell, quoted_decode() in 
2.4.32 seems to already have a similar fix)

Thanks again!
