attachments are not received but send

[Leeheng86]

Hi!
I also have the same issue like #54 , my program will check gmail per hour automatically and reply with different attachment. It is almost 10% to 20% recipients report that they did not get attachments, but in my sent mails attachments are fine.

I know it is hard to reproduce circumstance(even myself) , my question is does ruby-gmail has any logging function for recording interaction between gmail server and program?

I will try if i can reproduce this.
Thanks.
