I bought my iPhone in August. I left the IT department for greener pastures this summer and no longer have control over our Exchange server. The IT Manager told me he had enabled IMAP, so I thought I was good to go on my iPhone for corporate e-mail (came from a Treo 750 and a Blackjack both running ActiveSync). Not so. Apparently, he enabled IMAP but didn't poke a hole in the firewall for SMTP. I understand why, as he doesn't want us to become a SPAM relay and get blacklisted by every domain in the known universe. Fine. Unfortunately, I can't use cwmx.com or my ISP's SMTP server, as our IT Manager ALSO has Reverse DNS Lookup turned on. In other words, our domain e-mail addresses see that I'm not really sending from "user@companyx.com" like my e-mail address says, decides the sender is spoofed, calls me spamination, and rejects the e-mail. Well, crap.
I've been trying Synchronica Mobile Gateway. It works okay, but two things suck: (a) it goes down... ALL... the time. It's down right now, and I haven't received a single e-mail since 7:18 A.M. (b) it places that stupid 'This message was sent via Synchronica Mobile Gateway' on every single e-mail. This is unprofessional and it worries me that people will look down on me because I gave my username/password to a third party outside our organization. While we don't have a specific policy against that, I'm sure they'll be writing one to target me before this is all said and done. I've looked into IPXsync, but unfortunately, it's vaporware at the moment.
Does anyone know of any other alternatives? Are any other companies doing what Synchronica is doing? I think most are not because they know that at some point Apple will come in, license ActiveSync for iPhone, and all their work/money will be wasted (that's my #1 complaint with Apple, that it consistently craps on developers).
Any advice, experiences, etc?
Update: I just switched to trymobilegateway.com isntead of syncml.biz for e-mail retrieval and its working again, faster than ever. I recommend this change for other folks.
