We are using google apps to host our email services and got our application to send emails out using gmail servers. The limitation to this approach is that we can send only 500 emails per day.<p>What are you guys using to send emails? Are you hosting an email server yourselves?
Dreamhost hosts my mailbox. I have a nice setup that runs server-side where SpamAssassin automatically trains CRM114 and the two check each others' results and make sure they don't produce opposite conclusive answers. I use mutt as an MUA and Postfix as an MTA, with DynDNS's outbound mailhop service to get around the firewalls imposed by various lame ISPs.
google apps myself, I haven't hit the limit. Just create more users and append a # (noreply1,noreply2) to the end of them. I thought I read that was google's answer for when your breaking the limit.<p>Question for you, what are the limitation, besides this, you've had with google apps mail servers?
I've got a somewhat related question:
If a bunch of guys that were used to Exchange and the internal calendaring/syncing with phones/etc. left, and wanted to break their MS bonds and embrace oss, what would they use?
Basically - is their a compelling alternative that would still work with Blackberry?
I use courier right now. But I've migrated from courier to dovecot for pop3/imap, and I'm planning to migrate from courier to postfix for smtp. Courier is just too limited.
