Hi there


I've been having issue connecting to our mail server, mainly with slow SMTP connections using iPhone over 3G on the Vodafone network. The issue is borne on both 3G and 2G. To make an authenticated connection with our SMTP/IMAP server takes up to two minutes to send a simple email with the word "test" !  So we looked at getting to the cause of the issue - .... hmmm - smell my finger - hmmm stinks of Vodafone....

After some delving, IP addresses are dynamically assigned when connecting to the Vodafone network with the iPhone. (Clearly i thought this would be the case).  After some more delving, these do not have a reverse DNS entry. Pardon me?  No PTR?  Meaning, you are now happily connect via Vodafone 3G, and you look like a spammer!  How brilliant. Grrrrrrr.....

Why cannot Vodafone provide PTR? Isnt it a fundamental and basic requirement of APNIC? Just a standard naming convention for its IP allocation for mobile devices would be good! Some PTR, any PTR, voices of Basil Faulty hitting car with branch - "your a naughty boy"

It could be as simple as 120-121-85-255.vodafone.co.nz  - standardised naming convention throughout is IP pool. 

I dont think im the only one with this issue - this would most likely apply to others running their own network or mail server, those who want to keep their IMAP mailbox folder structure intact.


Whats the story here Vofafone?  My mail server hates you, and right now so do i. Perhaps you could be more up with the play and less of behaving like a expensive draconian Nanna again.


Bravo !
