[Cialug] Gmail rejects

[Matthew Nuzum]

In my experience, using Gmail as a smart host, which requires you to login
with your gmail username, causes all e-mails to appear to come from the
gmail user the server logs in as. Because of this, I stopped using Gmail as
a smart host. If the outbound e-mail volume is small (less than 12k emails
per month), Sendgrid has a good free tier and there are plenty of tutorials
for using them as a smart host for common MTAs.
