php - Email treated as SPAM when has Links -


i've work day long on crazy problem.

i created html email sent massively. use phpmailer , tried mail function. both phpmailer, it's smtp feature , native mail function works well.

good - pass spam filter

the problem when put link in html code, email turns spam. not links. if put link href "http://www.google.com" passes filter. samething on company domain name "http://www.sequencedigitale.com", passes filter well.

<a href="http://www.google.com">this google website</a> 

wrong - don't pass spam filter

what turns me crazy when put same domain name server process email submission. have 3 domains names point on server, every of 3 don't pass filter.

<a href="http://careers.fieracapital.com">this doesn't pass filter</a> 

i checked on blacklist checkers , ip isn't block on 100% of lists.

the ip 184.107.100.61

the problem happened me on hotmail, outlook , on server runned plesk. passes filter on gmail.

any appreciated.

thanks.

carl.

email sent massively.

that's sort of spam is, can try make less spammy passes through more filters.

it's make address 1 that's smtp server (use reply-to if want replies). if can email server that's reputable, closer goal.

it's dependent on proprietary filters microsoft using, there's not whole lot can done.
