After a couple of hours of head-scratching I thought I'd ask the question...
Since my ntlworld email account was migrated to the new platform I've been successfully using my wi-fi Palm PDA to access my email whilst at home. A couple of weeks ago I lost the ability to send via smtp.ntlworld.com although this had previously been working. I checked my settings and there appears to be nothing wrong (server: smtp.ntlworld.com, smtp authentication enabled using my .....@ntlworld account and the correct password, SSL enabled, Port:465). Whenever I attempt to send mail the PDA times-out, saying there is no response from the smtp server. To reiterate, this is when I am connected via wi-fi to my router at home, which is connected to Virgin Media (cable). I have checked and double-checked the settings and can see no problem (laptops in the house work properly with the same settings).
The one thing that did occur to me was that Versamail (the Palm POP3 client) cant connect to Gmail over port 465 (it does work with port 587), unfortunately port 587 on smtp.ntlworld.com has the same problem.
I can't use VM webmail as, unlike Gmail it lacks a simple way to directly access it via a mobile-friendly page.
I do have a solution to the problem-I send via smtp.gmail.com (I have my Gmail account associated with my ntlworld account so messages appear to com from my ntlworld account), but I'm just rather confused
Perhaps once the ntlworld smtp server is migrated fully to the gmail platform I'll be able to use port 587 to connect to that one (and I'll be able to use it from wherever I happen to be????)
Many thanks in advance for any replies.
