Mail not sending with PHPMailer over SSL using SMTP

Question

I am trying to use PHPMailer to send e-mails over SMTP but so far have had no luck  I ve gone through a number of SO questions  PHPMailer tutorials and forum posts but still cannot get it to work  I ll document as many of my failed attempts as I can remember to save time  but firstly here is the code I am using    lt  php     session start        error reporting E ALL       ini set  display errors   On         require  includes class phpmailer php        include  includes class smtp php         mail   new PHPMailer           name     POST  name         guests     POST  guests         time     POST  time          message     lt h1 gt    name   has booked a table for    guests   at    time   lt  h1 gt          mail- gt IsSMTP       telling the class to use SMTP      mail- gt Host          ssl   smtp gmail com      SMTP server      mail- gt SMTPDebug    1                         enables SMTP debug information  for testing       mail- gt SMTPAuth     true                      enable SMTP authentication      mail- gt Port         26                        set the SMTP port for the GMAIL server      mail- gt Username      myEmail gmail com      SMTP account username      mail- gt Password      myPassword             SMTP account password      mail- gt SetFrom  myEmail gmail com    James Cushing         mail- gt AddReplyTo  myEmail gmail com   James Cushing         mail- gt Subject       PHPMailer Test Subject via smtp  basic with authentication        mail- gt AltBody       To view the message  please use an HTML compatible email viewer         mail- gt MsgHTML  message       address    myOtherEmail me com        mail- gt AddAddress  address   James Cushing         if   mail- gt Send              echo  Mailer Error       mail- gt ErrorInfo        else           echo  Message sent            gt    Firstly  when I run this code now I get two different errors  On my local server I get the error  SMTP -  ERROR  Failed to connect to server  Operation timed out  60  The following From address failed  myEmail gmail com   Called Mail   without being connected Mailer Error  The following From address failed  myEmail gmail com   Called Mail   without being connected  I get moreorless the same error running the same code on my web server  but the first line is  SMTP -  ERROR  Failed to connect to server  Network is unreachable  101   Obviously it s worth pointing out that I m not using the literal  myEmail gmail com  but I ve substituted my own email out for this post   Things I ve tried  - Using the iCloud SMTP server  - Using a different port  - Enabling the OpenSSL extension in my php ini file  - Copying code from various PHPMailer examples  - Using Google s  DisplayUnlockCaptcha  system to enable connections  - Sending to and from different addresses  - Removing the   gmail com  from the Username property  - A number of other things I can t remember  This has now been driving me mad for about a day  so if anyone can solve it they will be a hero   Thanks

Don t use SSL on port 465  it s been deprecated since 1998 and is only used by Microsoft products that didn t get the memo  use TLS on port 587 instead  So  the code below should work very well for you   mail- gt IsSMTP       telling the class to use SMTP  mail- gt Host          smtp gmail com      SMTP server   mail- gt SMTPAuth     true                      enable SMTP authentication  mail- gt SMTPSecure    tls                      sets the prefix to the servier  mail- gt Host          smtp gmail com           sets GMAIL as the SMTP server  mail- gt Port         587                       set the SMTP port for the

Firstly  use these settings for Google    mail- gt IsSMTP     mail- gt Host    smtp gmail com    mail- gt SMTPAuth   true   mail- gt SMTPSecure    tls     edited from tsl  mail- gt Username    myEmail    mail- gt Password    myPassword    mail- gt Port    587     But also  what firewall have you got set up   If you re filtering out TCP ports 465 995  and maybe 587  you ll need to configure some exceptions or take them off your rules list   https   github com PHPMailer PHPMailer wiki Troubleshooting

I got a similar failure with SMTP whenever my client machine changes network connection  e g   home vs  office network  and somehow restarting network service  or rebooting the machine  resolves the issue for me  Not sure if this would apply to your case  but just in case   sudo  etc init d networking restart     for ubuntu
