Summary0005678: mailhook fails for large commits
DescriptionThe mailhook fails for large commits, with two problems:
* the generated mail is too large
* some python module can't be imported

This shouldn't happen. Even tough huge commits are rare, they are necessary sometimes (e.g. to check in larger dependencies).

Tried locally, the following two shell commands should fix it.

# postconf -e message_size_limit=200000000
# service postfix restart

The question is, are 200MB a good value *in general* ?

Also, I couldn't reproduce the ImportError, since 'future' is actually not imported (anymore).

The 200000000 limit was obtained by trying to notifying the whole wallet-webex.git history via e-mail.

However, even by setting this value on one controlled server, it is not expectable that *other* e-mail servers will pass that big amount of data through.

CG suggests to set this value to 16MB, which is a threshold that other email servers will allow too (or at least, it is the one for

4fa6e73 (gv-maintenance.git) message_size_limit is set to 16MB.

For changes bigger than 16MB the mail-hook will just fail!
