I have Postfix with smtp-auth, port 587, all works good I'm having problems setting an iPhone with smtp-auth sending, hoping some iPhone experts can point me in correct direction
on this iPhone, under SMTP, it has 'primary' SMTP server, correct host, port 587, SSL; under 'additional' there are ISP SMTPs (ADSL, cellular) servers, but, all entries are disabled, only 'primary' is enabled Emails are retrieved OK {same host as SMTP, IMAP, SSL) When i tried sending, sending failed, got this error on iPhone: 'copy placed in outbox,sender rejected by server' There is no apparent log entry at the SMTP server from this attempt; Later, after iPhone device returned 'home' the outbox email got delivered over WiFi/ISP's SMTP So, it seems to me, there is another SMTP entry, of ISP, that takes precedence?? again, under SMTP, only primary server is enabled (the one i'd like to use), other SMTP servers are disabled, but, email was delivered via ADSL ISP's smtp server to my Postfix server Perplexed, Voytek
