Send log as compressed attachment if it is large

[ghost]

Backups that add a lot of new files cause there to be a log which is so large that MTAs reject the email. It would be nice to have the log file gzipped and sent as an attachment in this case, or just make this a configurable option so this can be the default.

I have some thoughts here, but sending email attachments from a Unix shell is Not Fun^TM.

Thats a nice idea, i had already the same Problem when backupping a lot of changing RRD database files which caused a really hugh log.
(For now i just disabled the whole Borg output)

Sending an Attachment with Sendmail-Compatibility is indeed a pain... We need to build the multipart header by our own :-) but i guess there are already examples for that
