Guys! Thanks to some posts in this thread I tried Postbox as I was also looking for an alternative to Mac OS X Mail and originally considered Thunderbird. Even though Mail worked good I was looking for a more complex alternative to handle my mails professionally. After trying Postbox for a couple days I won't be switching back to Mail. Postbox integrates flawless with my gmail account and gets my mails organized just the right way. No more different sent mail account to search when using desktop application as well as iPad. Even return receipts I can request again, one of the lacking features in Mail.
Give it a try, I'm very happy with Postbox.![]()
I am also a paying Postbox customer but I've switched back to Mail due to Postbox sharing Thunderbird's behaviour of not always showing inline graphics inline on both received and sent email. That is a deal breaker for me and I suspect that it won't be fixed in Postbox until it is fixed in Thunderbird. I liked everything else about it with the exception of the limited support for plugins.
