I'm developing an email client and just found that some emails do not have a "To" header field thus I don't 'know' who's the email intended for. Only a "From" and "CC" is provided and sometimes a "For" field. Is there any standard how to extract email address that the email is intended for ? (e.g. if To is missing look for For, if that's missing too look for turkeys :). See the sample below from an email I've just got.

Even worse it seems that some emails have a wrong "To" but the email was delivered to my inbox anyway due the "For" header. I'm not sure how I can detect that unless I look in DB to see if the "To" email is actually one of mine.

I have read (https://support.google.com/mail/answer/12096?hl=en) that any Gmail account can receive emails for its plus alias.
So for account#gmail.com when I send email to alias+account#gmail.com
I receive following reply:

Do I need to enable something? Or this functionality is no longer available?
You need to put it the other way around, so instead of alias+account#gmail.com, use account+alias#gmail.com.
My application uses PHPMailer to send email through gmail. It was previously working fine, but it appears maybe now gmail is categorizing my email as spam before it is sent out to the recipients. Below is an example of one of the messages that were rejected. I removed URL and Email addresses to protect the innocent. Is this as simple as making t he email body text better so it isn't seems as spam, or is there a more precise fix for this?

i have a problem with sending email from my server to hotmail and gmail. seems the mail is just dropped, no returned bounce email notices etc. the emails just vanish. I have looked around for solutions on the net but nothing seems to help. below are the email headers of one mail which is send correctly to another big provider, without any problem. As i cant make any sense of it as to why hotmail is rejecting these mails, i hope someone can make something of it and give me directions on maybe a solution:

I have dkim installed, tested all settings with mxtoolbox (dns, smtp etc) al seems to be right, but still Hotmail and Gmail is not accepting emails from my server (which holds about 25 domains, all sending through this server).
thanks!
Gmail ending up in spam is related to designated user not being able to send out through main server. case you have server: mail.server.com and you are sending mail with my.domain.com, the spf record needs to hold the ip6 of mail.server.com in spf. Obviously rDNS needs to be correct. For the hotmail problem, this is purely microsoft. you can check up with support from outlook.com, but only thing you get is "we dont block your server, although some emails are filtered. this can be caused by mitigation time, which can take up to 48 hours". Thats it. No messages are returned, simply dropped. Maybe msn.com outlook.com and live.com are experiencing the same problem.
I've been frequently receiving emails with the subject line "failure notice" and I've included one example below.
Should I be concerned about this and what, if any actions do I have available, as it looks like my email address is being used as the return path.
Note I have changed the details sightly to "mydomain.co.uk", the email that is not mine to "removed_not_my_email#yahoo.com" and my email to "my_email#mydomain.co.uk"

There is no verification on the sender in SMTP. Anyone can send email from whatever emailadress they can think of.
Spam & malware is distributed using this fact. Circumventing certain spamfilters because the sender-address/return-path seems legitimate.
The notice that 'content presents a potential 552-5.7.0 security issue' could mean that an executable was attached. Maybe harmless, but probably a virus or malware.
Not nice, but also not much you can do about it.
To avoid your email address being used, in the future, as source of this practice, protect your email address.
Don't post it on webpages in clear.
Use a temporary emailaddress when subscribing to sites and or mailinglists.
The Problem: All Wordpress registration emails (with the password) are getting blocked by google.
Details:
The site's email is currently being hosted by google apps. THOSE emails WILL send to gmail addresses. So the problem is specifically emails generated by Wordpress.
What I've tried:
I've installed several SMTP plugins, and they all allow me to generate test emails (via the plugin settings page) to my gmail account. However, they do not resolve the issue for new user registration emails.
I've also attempted to change the "from" email settings, but I'm not really sure how to do this. You can see in the email header pasted below, that I'd probably need an address that ends with #performancehosting.axiom9.com for this to make any difference.
Review:
It sounds like wp_mail() is the problem, I'm hoping someone can offer a solution. My suspicion is that it has something to do with the return-path in the email's header, but I'm not sure what to do with this information.
Here is the header from the email generate by Wordpress (which won't arrive at gmail addresses):

It turns out that there was a plugin which was probably to blame. I changed the site's configuration to use the default Wordpress "new user" email and it suddenly worked. It would still be interesting to understand more about the interface between Wordpress and PHP_mail(), but my problem is solved for now.
