sending emails with ruby where the address has a gmail style '+' filter

When I try and send an email say me+test@gmail.com it throws (Net::SMTPSyntaxError) "501 5.1.3 Bad recipient address syntax" is it me or is the syntax checker a little too str开发者_StackOverflow社区ict?

Has anyone come across this before/have a patch for net/smtp?

Very quick thought (without research so apologies if I miss the mark!): try single quotes around the address 'me+test@gmail.com' to make it a literal string?

Otherwise, this post seems to address the problem with Exception Notifier Plugin and Rails 2.2.2+.

The problem was upstream - using sendgrid.

Are you sure that's coming from ruby and not from the smtp server? – flyfishr64
