Edit report at https://bugs.php.net/bug.php?id=76663&edit=1 ID: 76663 Comment by: a at b dot c dot de Reported by: standus at post dot cz Summary: fwrite(): send of X bytes failed with errno=32 Broken pipe Status: Not a bug Type: Bug Package: *General Issues Operating System: CentOS, linux, windows PHP Version: 7.0.31 Block user comment: N Private report: N New Comment: "No other way exists to verify email address than ask smtp server." The only way to reliably verify an email address is to send an email to the address asking the recipient to reply (maybe include a link that they can use to confirm they received it). You might get back an error claiming that the address doesn't exist. But not getting an error doesn't prove the address does exist.

Its different think. No other way exists to verify email address than ask smtp server. ------------------------------------------------------------------------ [2018-07-25 18:54:29] spam2 at rhsoft dot net you need to understand that there is no problem with fwrite it is just the messenger you can't treat others mailservers like you do - frankly you can't even use unconditional sender-verify that way unless you want get blacklisted stop to argue - what you are doing is utterly bullshit and you get what you asked for - for normal usage after a successful fopen that never does happen and when it happens it points out a serious problem you want to know about would you mind to tell the ip of your machine so that it can be added to blacklists? ------------------------------------------------------------------------ [2018-07-25 18:19:05] standus at post dot cz I already tried try catch but its the same, not solved. It will still produce Notice. ------------------------------------------------------------------------ [2018-07-25 18:14:52] standus at post dot cz I dont need answer for architecture or solution, I reported problem with fwrite function. ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
