Before you read on I shall mention my solution costs US $14.95 one-time if that doesn’t appeal to you then this wont be worth reading. I totally get it if anyone doesn’t want to, its annoying that Apple didn’t implement this within Mobile Me, who the **** wants an @me address anyway! Anyway.... here is How To Like you, I wanted to use MobileMe with a custom email address, following another post on this forum I got it working with GMail, taking advantage of their SMTP servers, however their was one cosmetic bug, and that was all the emails I sent showing up as I didn’t really like this and thought it looks fairly nasty so I tried to find a service that can force messaging going through their SMTP server to change the "from" field. (To my custom address). This is the Google/Microsoft "bug" as seen in hotmail (with my email addresses blanked out but you get the idea) As I understand it will affect anyone using Hotmail or Outlook I also wanted to maintain the push functionally of Mobile Me so editing the SMTP server was the only option. What’s the catch? You have to sign up to a service called fastmail and to use their SMTP servers pay a one time fee of US $14.95 one-time, with the exchange rate in the UK being so good at the moment I thought this was a pretty modest asking. I also wanted to maintain the push functionally of Mobile Me so editing the SMTP server was the only option. Step 1: Forward all email from the domain you wish to use to your Mobile Me account in my case firstname.lastname@example.org forwards to email@example.com Step 2: Configure Mobile Me on your iPhone as you would normally, send an email to your custom domain and make sure its being forwarded to the Mobile Me email. Step 3: Register an account at Fastmail you will need the member plan https://www.fastmail.fm/mail/?MLS=LN-*;UDm=49;MSignal=SI-*N-1*Mem Step 4: Log into your new fastmail account via http://www.fastmail.fm/beta/ Go to Options -> Personalities Double click your default personality. There should be a checkbox "SMTP force From" Make sure it's checked Click "Save Personality" Your settings will look something like this Make sure its set as your "default personality" if you dont see the "SMTP force from" option you’re not in the BETA version of the website make sure the URL is /beta/ Step 5: Almost there, grab your iPhone and Go to Settings Mail, Contacts, Calendars under accounts select your mobile me account Account Info SMTP Add Server... Configure it as Server On Hostname: mail.messagingengine.com Username: (your fastmail login including @fastmail.fm) Password: (your fastmail password) Use SSL: On Authentication: Password Port: 465 make sure all SMTP servers are turned off apart from mail.messagingengine.com Step 6: Ok now try and send an email, everything *should* be working and contacts will see all emails as your custom domain. Congrats A couple of notes ----------------------------- Its normal for EMails within the Mail client to show the address as you@mac/me.com this will be changed once it gets to fastmail's servers. So unless someone can find an SMTP server that does the same free of charge, this is a full featured no bugs solution (as far as I can tell) I want to thank zhak for helping me request the feature http://www.emaildiscussions.com/showthread.php?t=53336 And Fastmail for implementing my feature request http://www.emaildiscussions.com/showthread.php?t=53342 PS: Im not affiliated with Fastmail in anyway, if anyone can find a free SMTP server that will force add a custom email address then just use these instructions in conjunction with the free SMTP server. I realize this looks like an advert for their services im just sharing how I got working and if people feel that its worth the money they can use it as well. Finally if you want an email to test this with, http://www.guerrillamail.com/, make a quick account their and send it email, the from field should show your custom domain. If you want to make sure the bug is gone open a Hotmail account (serious effort involved) No more sent on behalf of, note neither @Mac or @Me ends in @......tl.com, ive just blanked out some of my email to protect my identify.
