    desperately seeking help


    I have a site that provides free photos but I am having a serious problem with mail being sent from the site- about 1/2 of the emails sent never reach the destination- but 1/2 do? Any emails sent by horde will go through but 1/2 from the site using php mail() any ideas? Out of 50 registers a day only 23 will actually work

    AFAIK, PHP mail() uses sendmail; what does horde use? That might give you a clue.

    Actually imp (horde), php, perl or anything else is going to use the system mailserver regardless of what's installed. We use Plesk which uses qmail instead of sendmail so a call sent to sendmail just hits a softlink to redirect to qmail.

    In any case, it sounds like an authentication problem or possibly a misconfigured mailserver that is being rejected by anyone performing dns lookups. More and more people are requiring a reverse so if the ptr on the mailserver IP is missing or not correct, a lot of servers are going to reject the mail outright. If that was the case, the bounces should contain an obvious error code though.
